Fun Fact:The Indian dead leaf butterfly doesn’t like to fly. Just like a dead leaf skims the ground when a gentle gust of air lifts it into the air; the dead leaf butterfly too occasionally flits around the ground only when he absolutely must. He chooses to stay-put, snacking on fallen fruits, moving only when food runs out or there’s danger nearby.
Fun Fact:Despite its “satanic” appearance, the leaf-tailed gecko is a very mild-mannered creature and is relatively harmless. Her young are pretty shy too. In order to prevent them from being eaten after birth, the mother lays her clutch of eggs inside the dead leaves of a plant, so that her little ones (which resemble tiny dead leaves) get camouflaged completely once they’re born.
Fun Fact:The bird dung crab spider is a master of deception. In order to play the role of “bird dung” with conviction, the spider sprays a thin jet of its own silk on the leaf and then applies some on parts of its body. It then lays down on the silk and waits. From the air, the spider now looks like a piece of bird poo, laying in a puddle of white, watery bird droppings.
Fun Fact:The moss mimic stick insect takes mimicry to a whole new level. The stick insect’s moss-like cuticles take on the colour of the tree it lives on. You may see insects of the same species in different shades of greens and browns. Another fun fact – the moss mimic stick insect’s eggs resemble plant seeds. She doesn’t lay them in clusters like other insects. Instead, she loosely fixes them onto different trees so that they can fall or be carried away by birds, hatch elsewhere and expand her kingdom.
Fun Fact:The tadpoles of the Malayan horned frog have a really unique physiology. Unlike other frogs, their mouths are upturned and they cannot eat underwater. They need to swim to the surface and feed-off anything that is floating on the water’s surface (compared to other tadpoles which live underwater and eat aquatic algae).
Fun Fact:The Orchid mantis’ camouflage is so effective; more number of butterflies, bees and other nectar-eating insects are actually attracted to the orchid mantis, than they are to the actual flowers!
Sex in the animal kingdom is messy and sometimes a man just doesn’t know how to take ‘No’ for an answer. While some females resort to the protection of the herd to keep insistent males at bay, others stand their ground and refuse to let the men touch them. But, what this species of avian does, takes the battle of the sexes to a whole new level.
Mating season can be a difficult time for everyone. Males can get very handsy during mating, forcing themselves on unwilling females. While some animals give in to the subjugation, others join forces with one male, forcing other marauders to keep away. But there are few animals that take things to the next level and develop unique physiological mechanisms to keep out unwanted advances. This is the story of one such animal.
For plume and penis
Male ducks are annoying. They’re a bunch of irritable, insistent and hormone-driven creatures that can become truly trying during mating season. Just ask the females and they’ll vouch for this.
Male Muscovy ducks, in particular, can be difficult partners for females. These ducks can turn from calm and collected to crazed and commanding in a second during mating. They are one of the few creatures in the animal kingdom who turn rapists during mating season.
When a female refuses to allow an unwanted male to impregnate her, the Muscovy duck uses his abnormally long penis to force himself into the female. The penises of the Muscovy ducks measure 40 centimeters long; which is approximately half their body length. During insemination, they forcefully eject the penis into the females, pushing through and navigating the vaginal walls, until they reach the egg.
The entire process takes such little time; the males everting their penis and entering the female in less than half a second; that females have no power to stop the males from inseminating them. The video below shows how long and fast a male duck’s penis can actually be, during mating. Take a look.
Labyrinthine ladies and their convoluted coition
Evolution of physiological traits is a matter of necessity. Female ducks choose their partners based on various criteria, right from the health of their plumage to the way the males complete the courtship ritual. But marauding males often circumvent tradition and go straight to the act; necessitating females to take matters into their own hands and protect themselves.
To prevent unwelcome males from inseminating them, female Muscovy ducks have evolved counter-clockwise vaginas, which are designed to trick males into thinking they were successful in mating with the females. So how does this work?
The inverted and twisted vaginas of female Muscovy ducks are made of constricted muscles, which face in the direction opposite to the clockwise male penises. They contain dead-ends and empty cul-de-sacs which are designed to receive the sperm of unwelcome males. When a male forcefully enters a female, the female tightens her vaginal walls and guides the penises into the dummy chambers and dead ends. When the male ejects, he does so believing that he is ejecting into the female’s egg chamber, when in fact he is ejecting into an empty, dummy chamber which is located far away from the egg. This helps the female preserve the egg for a more deserving and chosen partner, while also removing the threat of a roving rapist.
A study conducted by Dr. Patricia Brennan from Yale University showed how the Muscovy ducks’ reproductive anatomy actually looks like. The results of the experiment showed how males find straight vaginas easier to navigate, but find it extremely difficult to evert when the vaginas are twisted. This could explain how female Muscovy ducks are taking back control over reproduction through ingenious reproductory evolution.
If it’s a mate she’s chosen for herself, the female relaxes her vaginal muscles, turning the inverted and counter-clockwise vagina into a straight tunnel-of-sorts, allowing the male to inseminate her egg with ease.
Dugongs are marine animals which belong to the family Dugongidae. They are part of the order called Sirenia aka sea cows, which also includes the manatees. They can be found dispersed across the Indian ocean, Pacific ocean and the region between East Africa & Australia.
Here are five facts about them:
Apart from manatees, dugongs are the only marine animals that are strictly herbivorous, eating sea grass, weeds and aquatic plants. All other marine animals are omnivorous.
The closest relative of dugongs is the Steller’s Sea Cow, which was driven to extinction in the mid-1700s.
A dugong’s gestation period lasts one year and females give birth once every 3-7 years.
Although they resemble seals and walruses in appearance, dugongs are actually more genetically similar to elephants. That’s because these animals evolved from the same ancestor.
According to the IUCN Red List, dugongs have a “Vulnerable” classification; meaning they are very vulnerable to becoming extinct if conservation efforts aren’t set in place. As of today, less than 7500 dugongs are alive in the world.
The name “dugong” comes from the Malay word “duyung“, which means “Lady of the Sea“. Before scientists officially documented this species, sailors & fishermen out at sea assumed dugongs (and their cousins, the manatees) to be mermaids, sirens and other mystical creatures. This was predominantly because of the way these animals swam.
Dugongs and manatees rise out from the underneath the water and perform tail-stands (where they stand & balance on the tip of their tails) when coming up for air. This prompted sailors & fishermen to assume they were the mythical sea-dwelling creatures they grew up hearing about.
Posssums are marsupials (pouched mammals) that are found in North America. They are the only marsupial species found outside Australia and New Guinea. They belong to the order Didelphimorphia, to which belong 95 species of possums.
Here are 5 fun facts about them:
Possums are renowned for their ability to “play dead”. In reality, possums don’t actually “play” dead. Their paralysis and almost-dead like state is an involuntary physiological reaction where their nerves and muscles literally freeze and stop working for hours due to stress. This in-built defense mechanism has allowed the possum to survive from pre-historic times.
Lyme disease is a tick-bite induced disease that results in terribly itchy and inflamed rashes, joint pain and fatigue. Possums in your backyard is a great defense against Lyme disease. It’s been found that possums prey on over 5000 of the ticks and fleas that spread the bacterium Borrelia burgdorferi, which causes Lyme disease.
Apart from the venom of the Coral Rattlesnake, possums are immune to all other snake venom. That’s why they regularly prey on snakes in the wild. A few years ago researchers created an anti-venom using possum peptides (short chain amino acids linked by peptide bonds), which they injected into mice. They then injected snake venom into the mice only to find the venom absolutely useless.
Rabies virus require very hot temperatures to develop and spread. But possums have very low body temperatures compared to other mammals and this makes them invulnerable to rabies. You can almost never find a possum with rabies.
Primates aren’t the only species to be gifted with opposable thumbs. Possums have opposable thumbs called “halux” on their feet and they use them to climb atop the steepest trees and into the deepest sewers in search of food.
Contrary to popular belief, possums and opposums aren’t the same animal. They also don’t belong to the same species. For one, possums belong to the Didelphimorphia order in North America, while opossums belong to the order Phalangeridae in Australia. Both animals look similar, but behave completely differently. It was because of this similarity in physical features that led scientists to confuse the opposum for a possum.
Sea Sponges are multi-cellular creatures that do not have a brain and organ systems and depend on the constant flow of water through their porous bodies to get the oxygen and food they need to survive. There are over 9000 recorded varieties of sea sponges in the world today and they can be found at various depths right from the seashore to the abyssal zone, which is the deepest part of the ocean.
Here are 5 fun facts about them:
Fossil records of sea sponges indicate that sponges first made an appearance on the Earth 650 million years ago. This makes them one of the earliest life forms on the planet.
There are currently 480,931 marine species known and on record and an estimated 2 million that are as yet unrecorded and unknown (i.e. there is not enough evidence – be it visual proof or physical proof – to classify any unknown animal as a distinct species) in all the lakes, seas and oceans of the world. It’s believed that 75% of the world’s entire marine population (480K + 2 Million) accounts for sponges.
Since they don’t have any age-rings (like in trees), it can be hard to accurately estimate the age of a sea sponge. But analysis of growth rates indicates that some sea sponges grow 0.2 mm (0.000656168 feet) per year. Based on this, sponges as small as 1 meter (3.2 feet) wide may be over 4500 years old!
A sea sponge in the Caribbean – Tectitethya crypta – produces two chemical compounds which can treat certain types of cancer and HIV. The chemicals – spongothymidine and spongouridine – have been used to develop the HIV drug Azidothymidine (AZT) which can be used to prevent mother-to-child and needle-to-skin AIDS/HIV transmission. The same chemicals have also helped create medication for leukemia and herpes.
The biggest debate since the time of Aristotle has been – “Are sea sponges plants or animals?” Although they resemble plants in appearance and remain permanently fixed to the spot they grow on like plants, sea sponges are not plants. Why?
– Sea sponges can’t produce their own food like plants and rely on stray organic matter to float into their pores via the flowing water.
– Sea sponges have an immune system like other animals which reject dissimilar cells if transplanted into them. Scientists need to use immunosuppressants to successfully transplant dissimilar cells into their bodies.
– Finally, some sea sponges produce and release sperm to indulge in sexual reproduction.
These characteristics makes sea sponges inherently animal-like.
Today, you can find a feminine hygiene product called “Menstrual Sponges” on the market. Basically, these are sea sponges that are used as re-usable tampons. In many parts of the world (especially in developed, first-world countries), sea sponges are a favoured alternative to toxic, non-biodegradable and expensive sanitary pads and tampons. Here is a link to theTop 5 most preferred sea sponge tampons.
Centipedes & Millipedes both belong to the group “Myriapoda“, under the phyllum “Arthropoda“, which includes spiders, crustaceans and insects. We know they have a seemingly never-ending number of legs, with one having more legs than the other (20-350 legs in centipedes & 40-750 in millipedes). But is that the only difference between them?
5 differences you didn’t know existed between centipedes & millipedes
Centipedes are flat, while millipedes are cylindrical. Centipedes are yellow-gray in colour, while millipedes are reddish-brown or black in colour.
Centipedes have a single pair of legs in each segment/section of their bodies. Millipedes have two pairs of legs in each segment/section of their bodies. Centipedes’ legs are spread outwards and away from their body, towards their side. Millipedes’ legs are directly under them.
Centipedes are venomous, whereas millipedes are not.
Speaking of venom, centipedes use highly-toxic venom like hydrogen cyanide or hydrochloric acid to injure, immobilise and hunt small prey like insects, worms and in the case of the Venezuelan giant centipede, bats. Millipedes on the other hand, are predominantly vegetarians, dining on decaying leaves and rotten tree bark. They only eat insects if they are easily available and the millipedes don’t need to expend too much energy catching them.
Centipedes die if they don’t find a wet and moist place to live, whereas millipedes are quite versatile and can adapt to any environment – dry or moist. That leggy arthropod that just crawled out of your kitchen sink – that’s a centipede. It’s cousin you see scuttling around inside the storage boxes and wall cracks in the basement – that’s a millipede.
During mating, centipede males leave bundles of sperm next to female centipedes and move away. The females use these bundles only when they find the perfect nest to lay the fertilized eggs (if the timing isn’t right, female centipedes store these sperm bundles for a better day). Millipede males & females on the other hand, engage in sexual intercourse to reproduce. Male millipedes have been observed giving “massages” to females to get them in the mood for sex.
A jellyfish’s body is made of 98% water. They can dehydrate and disappear if they wash up on shore on a very hot & sunny day.
Jellyfish have the ability to clone themselves. If injured or cut in half, a jellyfish will heal itself and then clone itself to create two healthy organisms.
The Turritopsis nutricula jellyfish found in the Mediterranean Sea is capable of reversing its age once it reaches adulthood. How? When the Turritopsis nutricula becomes an adult, it starts changing its fully-grown cells into infant cells, essentially becoming a baby. This way, it remains young always. It is the only recorded animal to be completely and truly immortal.
In early 2000, fishermen in the Gulf of Mexico caught a monster-size jellyfish – almost 70 feet long and with sharp, extremely poisonous tentacles. This jellyfish was pink in colour and had never been sighted before. Scientists dubbed it the “Pink Meanie” and it is now one of the rarest and the second largest species of jellyfish in the world, reaching record lengths of 100 feet. The only jellyfish larger than this is the Lion’s mane jellyfish, which stands at 120 feet (that’s 3.5 times longer than a telephone pole!).
Jellyfish are more than 500 million years old, making them older than dinosaurs. Their ancient legacy can be attributed to their lack of a sophisticated physical body. Jellyfish don’t have any organs and only use their skin and a simple network of nerves to live. These combined make them very less physically demanding, requiring less to survive.
In 1991, NASA sent adult jellyfish into space on board the Columbia space shuttle. The objective was to find out whether space-born babies can survive a life both in space and on the Earth. It turns out that the baby jellyfish born in space developed extreme vertigo when they returned to Earth and most never learned how to swim in Earth-water after their extraterrestrial stint, because their newborn bodies never learnt how to recognise and deal with gravity. Researchers believe human babies too may face similar challenges if they are born in space. This makes relocation to Mars (or any space-bound journey) all the more challenging for humans.
Video: The world’s largest jellyfish has a very small, but very deadly predator – Anemone. Watch as this giant is ripped to shreds by a hundred little arms.
P.S: Featured image: Fried egg jellyfish – they live for only six months, born in the summer and dying in the winter.
Snail eggs are enjoyed as “white caviar” by people around the world. Did you know that a kilogram of snail eggs costs €4,000? These eggs are supposed to taste very earthy & strong.
The Giant African Snail is the largest snail on the planet, measuring 30 cms (almost 1 foot) long! Halfway around the world in China, you’ll find the world’s smallest snail – Angustopila dominikae – which measures only 0.86 cms long.
The digestive juices of snails are a great cure for bronchitis and acidity in humans. In a late 1990s survey researchers discovered that populations that eat snails regularly have a death rate that is 20X lower than populations that don’t.
Most land snails are herbivores and are practically harmless. On the other hand, all aquatic snails are omnivores, often the top of the food chain at the bottom of the ocean. Sea-dwelling snails use sharp harpoons and produce potent sulfuric acid to hunt.
Ever seen the slimy, mucous-like trail left behind by snails? Snails produce this mucous to protect themselves from the hard and dry ground they travel on. They spend 40% of their energy producing this mucous, which can really tire them out. That’s why many snails try to cheat their way out of this by using a slimy trail left behind by another snail.
Did you know snails have a mortal enemy?
Pouring salt on a snail is akin to signing its death warrant. Snail bodies are made mostly of water and other bodily fluids. When you pour salt on snails, the salt absorbs the liquids from the snail’s body through a process called “osmosis”. While a little salt will make the snail dehydrated, a lot of salt can kill it in minutes.
Farmers know this and routinely pour salt at the base of plants to prevent snails from wreaking havoc on them.
Here’s what happens when you pour salt on a snail (viewer discretion is advised)
When a snail starts drying up, its body produces a slimy substance to preserve any moisture that remains. The bubbles you see forming on the snail is the chemical reaction between the slimy mucous and the salt.
Zorse is a real animal. It is the cross-bred offspring of a zebra stallion and a horse mare.
The combination of the horse and zebra genetic material has given the Zorse a stunning genetic blueprint. A Zorse is always immune to the genetic diseases that are common to both its parents.
Although its fur colour can come from either of its parents, most of the physical features of the Zorse come from the Zebra father, making it a very strong & hardy animal, fit for the wild. However, its personality and temperament are exactly like its Horse mother, making it very easy to train. That’s why the Zorse is used as a pack animal in certain places of North America.
The Zorse has a 360-degree vision and can turn its eyeballs completely around to see. However, it has two blind spots – one behind the head and one directly below the nose.
The Zorse is by birth sterile and can’t reproduce. However, mating behaviours have been observed in the animals, both in the wild and in captivity.
Unlike Ligers and Tigons, which come from different combinations of lion and tiger mating, Zorse foals are born genetically the same irrespective of whether they are reared through a zebra stallion-horse mare mating or a horse stallion-zebra mare mating. However, since zebras are rarer and scientifically more valuable to breeding programs than horses are, no zebra owner voluntarily wastes time on having their female zebra give birth to a Zorse.
Chevrotain are super small in size. The various sub-species of the mouse deer range in size between that of a Chihuahua and a Jack Russell Terrier.
Although they resemble deer and have mousey faces, the chevrotain are not related to either of the animals. In fact, they belong to a separate, mostly-extinct species called Tragulidae, of which they are the only surviving members.
They have very long and sharp fangs which they use during battle for territory and mates. Their bites can put even Dracula to shame.
Female chevrotain are pregnant for most of their adult lives. They mate and get pregnant within a few hours of giving birth.
Chevrotains walk down into the river bottom and remain submerged for up to 4 minutes at a time when they sense the presence of predators. They may also create secondary burrows for themselves underwater where they stay until the danger passes. To see what this is like, watch the video below.
Okapi have tongues that are 30 cms long, which is approximately double the length of a standard television remote and three times the length of the average human tongue.
Okapi diet is as diverse as it is colourful. Okapi eat over 100 types of plants & fungi, red clay and charcoal. This type of diet ensures they get all the nutrients they need to be healthy.
New born okapi don’t poop until they are four to ten weeks old. Researchers believe this may be a tactic to avoid drawing predators through smell.
Mother okapi speak to their babies in infrasound, sounds that are too low for humans to hear.
Okapi release a black tar-like substance from their feet, which leaves marks when they walk. This could be a way of marking territory.
Okapi are extremely shy and live in secluded areas of the forest. Apart from calf-mother pairs, they seldom interact with any species, including their own. Till the time they were discovered in 1901 by British explorer Sir Harry Johnston, Okapi were called ‘African Unicorns’ because people thought they were a myth and didn’t really exist. It was only the indigenous tribes living in the Congo-Ugandan region who had occasionally seen the animals till then. Now they are found only in the Congo and are the country’s national animal.
Fruit flies can’t stand carbon dioxide. It makes them woozy and unfocused.
Fruit flies’ chromosomes look like barcodes.
Fruit flies have 100,000 neurons, which is a very high number for flies and it is this large brain matter that makes fruit flies so intelligent.
Fruit flies love their beer and males often get drunk on both alcohol and fruit. Female fruit flies have been observed rejecting males who get drunk often. (here’s an addition: humans like the same beer and wine as fruit flies…go figure)
Fruit flies enjoy sex as much as the human whose house they are in. Turns out sexually-deprived males go into depression and look for alcoholic drinks/food, while their sated counterparts steer clear of alcohol.
Fruit flies are a boon to science. They have a whopping 14,000 genes in their bodies (humans have 24,000…so that should tell you something) and extremely fast life cycles (fruit flies can mature from eggs to adults in as less as two weeks), which makes them perfect for genetic experimentations. In fact, fruit flies have contributed to 6 Nobel Prizes between 1933 & 2017.
So, what did fruit flies help us understand?
Role of chromosomes in heredity
Role of radiation in genetic mutation
Control of embryonic development through genetic experimentation
Pretty fun to sing isn’t it? And a wonderful sight it would be too. Especially in the wild.
Nature has her fair share of spectacularly beautiful animals and plants. Super colourful and oh-so-inviting, your only wish would be to touch the creature and feel it under your fingers. But do so and that may be the last thing you ever do.
If there’s one thing you need to remember about the wild, it’s that Colours = Poison.
Say hello to Aposematism
What do they call an animal that uses bright colours to ward-off danger? An aposematic animal of course. Aposematism is the biological process of using colours as signals to repel predators.
Animals brighten their skin pigments or even change their colours as warning to other animals not to cross their path. Plants, flowers, fungi and seeds use bright colours which indicate high levels of toxicity (which animals learn indicate ‘Don’t Eat’).
Aposematic animals & plants work in weird, but wonderful ways. While some are genuinely poisonous and use unique colours to their advantage, others are non-poisonous and mimic their more dangerous cousins to confuse and scare-off their predators, who otherwise may attack them.
But here you have below the list of 5 animals who really are poisonous and who use colour as a warning sign in the wild. Remember, they may look enchanting and you may want to touch them or pet them. But trust me, it’s better you stay away.
Now, without further ado, here are our top pics for pretty but potent animals in the wild:
1) Amazonian Poison Dart Frog
This one is most certainly the poster boy for ‘colorful but potent’ category in the wild (hence the feature image ;D)
Poison dart frogs are one of the most toxic creatures on land. Dart frogs don’t make their own poisons, but store the poison of the insects and smaller animals they eat. They then process these poisons and combine them to make a very potent toxin…something which can be severely painful for humans.
Local Amazonian tribes use the tree frog’s poison to coat their darts, which they use to hunt monkeys and birds. The most toxic of all Amazonian tree frogs is Phyllobates terribilis.
The Monarch Butterfly and the Pipevine Swallowtail store and use their prey’s toxin as a defence mechanism when they are older. Birds know they can be deadly to eat and avoid them. But other than a handful of these winged critters, most butterflies and moths aren’t poisonous. But the same can’t be said of their offspring.
Many caterpillars have a poisonous coating on their body, which protects them from being eaten by predators when they are young & helpless. While some poisons only knock the predator out for a few hours, others kill. A case in point is the formidable N’gwa or ‘Kaa caterpillar, which is found in Africa and whose toxin, according to researcher David Livingstone, which is a mixture of snake venom and plant toxin, has the capacity to kill an antelope.
3) Hooded Pitohui
Did you ever think a bird would be on this list?
The Hooded Pitohui, scientifically called Pitohui dichrous makes its home in the lush forests of New Guinea. The size of a dove, the Pitohui is the only documented poisonous bird in the world.
It’s toxin is a neurotoxin which numbs and paralyzes the victims. Luckily, this toxin isn’t fatal to humans, although the effects can take hours to wear-off. Sadly, the same isn’t true for its prey which are insects.
The Hooded Pitohui is part of a 3-species family, which also includes the Variable Pitohui and the Brown Pitohui, which are poisonous too, but not to the level of toxicity as their hooded cousin. The toxin has been found to be the outcome of the birds’ consumption of the choresine beetle. Such a nuisance is this bird to the surrounding tribes, it had been nicknamed Pitohui or ‘rubbish bird’ by the locals, which then was adopted as its official name.
Here’s an animal that can (and has) kill(ed) a human. Puffer fish are one of the most venomous animals on the planet and a single sting can bring down the mightiest of men. Often, human deaths occur when people unwittingly consume puffer fish organs in their meal. In animals though, its often a result of the puffer’s hunting or defence strategy.
The toxin the puffer fish contains is called Tetrodotoxin, which is a highly potent neurotoxin. The toxin slowly blocks all the neural transmitters in the body, essentially paralysing the victim, one organ at a time. At its peak, the Tetrodotoxin closes the wind pipe, slows down the lungs and stops the heart from working. Soon, the brain dies due to asphyxiation and lack of blood flow, killing the victim. Scientists believe Tetrodotoxin is 200 times more lethal than cyanide!
Want to know something even more unbelievable? The Japanese have a very special dish called Fugu which is made of puffer fish and is served during very special events. And guess what? Chefs deliberately leave a bit of the poison on the fish as an adrenaline-inducing treat for the guests.
5) Cone snails
They look harmless, inviting even. But pick one up and you’ll be stung faster than you can say ‘Oh no!’. Cone snails are another sea dweller that even humans need to beware of, if they don’t wish to be hurt or worse, dead.
Coming in a variety of shapes and sizes, cone snails contain a variety of neuro venoms (depending on the species) and can range in toxicity that’s akin to everything from a bee sting to a fatal hit. These snails shoot out harpoons, which are teeth-like organs which they use when hunting underwater. Any animal that has the misfortune of brushing against the cone snail will be the unfortunate recipient of the harpoon.
One species of cone snail that are extremely potent to humans is the Conus geographus or the Cigarette snail, whose toxin is said to be so quick-acting that victims have only time enough to smoke a small cigarette before dying.
Another gastropod that is poisonous – Nudibranch. You can read all about them here.
In the next article, we’ll focus on the Top 5 Most Colourful & Poisonous Plants and Fungi.

5 fun facts about Rhea dads
Rhea dads take on the sole responsibility of building the nest. This includes finding the right spot, procuring the right materials and building a good quality nest (and they do this for every female they mate with – which can be anywhere between 2 & 12).
Rhea fathers are a lot like penguin dads. They incubate the eggs and hatch it themselves (they usually attract the females to the nest – a shallow hole in the ground lined with leaves and moss – and have them deposit their eggs there).
These birds are great at using decoys. They use rotten eggs, mouldy fruit and other animal bait as decoys to distract predators from the nest. These decoys are lined around the nest and are replenished whenever they are consumed. This helps keep the clutch safe from harm.
Once the eggs hatch (after 6 weeks of incubation), the Rhea father spends the next 6 months caring for the chicks. The chicks burrow into their father’s feathers and revel in his feathery warmth. So possessive is he of his clutch, he even keeps the mothers at bay by attacking them with a ferocious charge and vicious bite.
Often, when they aren’t fulfilled by their existing brood, Rhea dads charge adolescent males as stand-in fathers, while they mate with more females and create a new nest. They then rotate between the nests, caring for the young and making sure they are properly protected.
Want to know more about this not-so-deadbeat dad? Take a look at the video below:
When it comes to fatherhood, its safe to say that the Rhea male is extremely devoted. He is one of those exceptions, who joins ranks of those animal dads who outrank mom in the art of child rearing.
