5 Fun Facts About Africa’s Great Migration

You may have seen it on television – it’s an event that National Geographic has always loved to film. A grand spectacle and a treat for the senses, the Great Migration in Africa is the annual movement of the world’s largest (non-human) land animal group from one part of Africa to the other, in search of food and safer breeding grounds*.

Wildebeests, antelope, zebra and big cats congregate for five months of rigorous walking, eating, birthing and killing. Here are 5 amazing facts about it:

  1. The Great Migration starts in Tanzania at the Serengeti and Ngorongoro Conservation areas and ends at the Maasai Mara National Reserve in Kenya. The migration starts in the month of November and the animals reach their destination in March.
  2. A recorded 1.5 million wildebeest, 200,000 zebra and thousands of antelope make the migration each year. The animals travel a staggering 2900 kilometres (1800 miles) in total, from Tanzania to Kenya and back during this journey.
  3. The Great Migration follows one of the most dangerous routes in Africa. Animals making the journey have to deal with hungry predators (lions, cheetahs & crocodiles), treacherous floods, the uncaring African sun, mean-spirited tsetse flies and physical tiredness. More than 250,000 wildebeests and thousands of zebras and antelopes die each year on the journey. This is excluding the thousands of calves who are left orphaned and vulnerable to predators after their mothers die. A recorded 3000 lions follow the herds on their journey, picking off the weak and the injured.
  4. More than a foraging mission, the Great Migration is a breeding expedition. Pregnant wildebeests move from Tanzania to Kenya for better environmental conditions for calving. An estimated half a million baby wildebeests are born annually during the migration. In the peak of the calving season (February), more than 8000 wildebeest calves are born in a single day!
  5. Although they look like they’re confused and panicked all the time, the massive herds of wildebeests, zebras and antelopes actually function together as one cohesive unit. They display a tactic researchers call “swarm intelligence”, where they carefully analyse, strategise and implement a  plan of action to get safely past any threat together. There’s no “I” in this family.

 

Bonus

There is still no established and accepted explanation for the occurrence of the Great Migration.

Some scientists believe the changing chemistry of the grass could be the reason for the movement. When levels of phosphorous and nitrogen in the Serengeti grassland reduces, the wildebeests may be encouraged to move elsewhere for more nutritious meals, acting as the catalyst for the Great Migration. Others believe that the migration may be the result of a co-ordinated effort helmed by a leader. But so far there has been no evidence of there ever being an alpha-wildebeest in any herd. Then there are those scientists who believe that the Great Migration is the consequence of instinct and DNA – a purely biological process that has no other reason.

Well, whatever the rationale, fossil records show that the Great Migration has been in occurrence in East Africa for over one million years.

5 Fun Facts About Crabs

Crabs are crustaceans, marine animals which have a thick exoskeleton made of a chemical called chitin (which is chemically derived from glucose). Crabs belong to the class Malacostraca, which means “soft shelled animal” and to the order Decapoda, which mostly includes marine crustaceans (like lobster, shrimp and prawn) that scavenge for food, as opposed to hunting them. This makes crabs soft-shelled scavengers.

Here are five fun facts about them: 

  1. There are two types of crabs in the world – true crabs and false crabs – classified so because of their differing physiology. True crabs have the traditional body structure of a crab – a short and shallow abdomen curled underneath the shell and 4 pairs of legs excluding the pincers. False crabs on the other hand, look a little like crabs, but not completely. They have longer abdomens and less than 4 pairs of legs. True crabs include spider crab, blue crab and ghost crab. False crabs include king crab, hermit crab and porcelain crab. There are a total of 5000 crabs in the world – 4500 true crabs and 500 false crabs. 
  2. The largest crab in the world is the Japanese Spider Crab, which measures 13 feet or almost 4 meters from one end of the body to another. In comparison are the Coral Gall crab, Pea crab, Marsh Fiddler crab and Flattop crab – all of which measure in at a teeny-tiny half an inch at adulthood. If you kept 4.5 standard sized mail boxes one-on-top-of-the-other on one side and a small pea on the other side…well, that’s how the size difference would look between these crabs.  
  3. A small species of crab called Lybia or boxer crab, carry stinging anemones in their pincers anywhere they go. Why?  Lybia are very small in size and they don’t have venom to protect themselves from predators. They use the anemones in a mutually-beneficial partnership where the anemone acts as their defensive, venom-filled gloves. If an animal were to attack the Lybia, the anemone would sting the predator, protecting the crab. In return, the crab takes the anemone to different water bodies, allowing it to feed-off various sources and gaining valuable nutrients not found in its native environment. 
  4. If a crab loses its limbs in a fight, it can grow them back in a matter of months. This is a feature that is also found in starfish and lizards. 
  5. Crabs walk sideways because their legs are positioned to the sides of their body and their joints bend outwards and sideways. The reason for this type of evolution traces back to the crabs’ feeding behaviour. As sand-digging scavengers, crabs never needed to move forwards or move fast. This meant they didn’t need forward bending legs (which are one of the reasons animals can walk or run fast) and could make-do with sideways legs and sideways walking. However, not all crabs walk sideways. Frog crabs and spider crabs belong to the handful of crab species that walk forwards. 

 

 

Bonus

There is a type of parasitic barnacle called the Sacculina, which injects itself into the crab’s body, takes control of the crab’s will and makes it do its bidding. Crabs infected by Sacculina can’t control their own body mechanisms and are forced to become walking, breathing incubators of Sacculina eggs. Read this highly-informative article to learn all about the relationship between the Sacculina and its crab host. 

Here’s what a crab infected by Sacculina look like:

5 Fun Facts About Hibiscus

Hibiscus, also called Rose Mallow, are flowering plants that belong to the order of Malvaceae – which are plants that grow in warm, temperate, tropical and sub-tropical regions. There are 679 species of hibiscus in the world. 

Here are 5 more facts about them:

  1. Hibiscus are edible and have a citrusy taste. Roselle, a type of red-coloured hibiscus found in West Africa is used to make a special type of prawn soup that locals eat as a delicacy during festive times. The Paites tribe in Manipur, India also uses hibiscus leaves in their cooking, for its uplifting flavour. 
  2. One of the primary reasons why people started brewing hibiscus tea was because of the hibiscus flower’s unique diuretic properties – it has the ability to stimulate urine production in the body, thereby helping the body throw out harmful toxins. 
  3. Hibiscus is the National Flower of 3 countries – Republic of Haiti, Malaysia and South Korea.
  4. Hibiscus flowers and leaves should never be consumed by pregnant women. Why? Hibiscus is an emmenagogue food – in addition to stimulating urine production, hibiscus flowers stimulate blood flow in the pelvic region. A pregnant woman regularly consuming hibiscus flowers, leaves or hibiscus-infused foods and beverages will confuse her body into setting the menstrual process in motion. This can lead to early labour or miscarriage! Even lactating mothers would be better off staying far away from hibiscus as consumption could lead to a stop in milk production. 
  5. Want to shine your dirty shoes before a big meeting? Go right into your garden and get a hibiscus. Hibiscus oil is a natural shoe-shiner and is used as a shoe polish liquid across Asia. 

 

Bonus

Women in Hawaii and Tahiti have an interesting custom. Single women who come of age, who are ready for marriage and who wish to be courted wear a hibiscus flower behind their right ear; while married women and betrothed girls wear the flower behind their left ear.

5 Differences Between Turtles & Tortoises

Turtles & Tortoises must have been the source of the “Find the difference” game, because they are two animals that most people can’t distinguish between. 

Turtles & tortoises are both reptiles which belong to the Testudines family of animals – animals which developed a bony/cartilaginous layer on their backs, which cover their bodies as a shield. They belong to the same group as crocodiles and snakes. 

A lot of times, many aspiring pet owners don’t know how to differentiate between a turtle and a tortoise and end up caring for them the wrong way. They give them the wrong food and expose them to the wrong living conditions. This results in many animal deaths. Those owners who try to do right by their pets by releasing them back into the wild, release turtles & tortoises in environments they actually aren’t supposed to, leading to more deaths. 

So, how can we stop this vicious cycle? By learning more about them of course. Here are the top 5 differences between turtles & tortoises

  1. Turtles can swim, tortoises can’t. That’s why turtles have webbed feet (sea turtles have full-fledged flippers) and tortoises have feet that have toes (like that of an elephant) which they use to walk & climb. 
  2. With the exception of the Sonoran mud turtles and Box turtles, all other turtle species have a streamlined and flat shell. All tortoises have deep, domed shells. The streamlined shells of turtles are highly-aerodynamic and reduce drag in the water. Tortoises never needed to evolve a flat shell because they never needed to swim. 
  3. Turtles live on an average for 80 years. Tortoises for 150 years. There have been instances where turtles and tortoises in healthy captive conditions lived well beyond their natural lifespans, some reaching an estimated 250 years of age. 
  4. Turtles are omnivores and like to eat a mix of plants and meat like larvae, insects, small fish and jellyfish. Tortoises are mostly herbivores and love their green leaves, with only a handful of species choosing to eat meat. 
  5. Female turtles come on shore only to lay eggs and will return to the water immediately after. Female tortoises on the other hand, often stay a few days protecting the nest and will return to their territories much later. If you’ve seen a turtle/tortoise lay her eggs near your property and you want to do your bit to give these eggs a chance to hatch (and not get eaten by predators), read this really-informative article by the Tortoise Protection Group here

Bonus

Okay, here’s a fun fact that can turn everything you’ve just learnt on its head. 

Scientifically speaking, there’s no distinct species called “tortoise”!

Okay, before you drop your device in shock, let me just clarify that there’s more to it.

So, according to taxonomy (the science of classification), all animals that have shells which cover their body completely are called “turtles”. What this means is that all tortoises are in reality a type of turtle

Let’s break it down further. The species called “turtles” includes – tortoises, terrapins (yep, that’s a new one) and turtles.

  • Tortoises are turtles which live exclusively on land.
  • Terrapins are turtles whose shells resemble those of sea turtles (only smaller), but whose legs look like those on tortoises and they swim in freshwater.
  • Turtles are actually sea-turtles which live in the ocean and do not remain long on land. 

Basically, all tortoises and terrapins are turtles, but all turtles are not tortoises and terrapins.

I’m Celebrating My First Anniversary At WordPress & Stories So Wild!

Hey everyone! It gives me great pleasure to announce that today – October 9th 2018 – is My 1 Year Anniversary at WordPress.

It was a year ago that I decided to pick up my laptop and start blogging about a topic that I was most passionate about – wildlife. I thought I’d take this time (and use this post) to talk about my experience so far and the amazing journey I’ve been on during this eventful year. 

I have always loved wildlife. As long as I can remember, I’ve picked up books that dealt with animals, plants, rocks, water bodies…the list is endless. Be it stories by Enid Blyton or memoirs by Jane Goodall, each book held my fascination and still do so today. Although I don’t have an academic background in wildlife and I don’t have much field experience, apart from the ocassional safaris and treks through protected parks, I have always felt the only prerequisite needed to write about wildlife is – passion. And that’s something I have in excess of. 

My journey this year has been amazing and I’ve gone through such a growth curve. I’ve learnt what kind of material ticks in the blogging world, what type of writing format I’m good at, what type of work my readers love to read and most importantly, what type of content gets the word out about the wonderful plants, animals & arthropods that occupy our world. I hope I’ve been able to (and hope to continue to) do my bit to help reduce ignorance and increase empathy towards the wild. 

I have been inspired by so many writers, painters, bloggers, photographers – both on WordPress and those outside it – the list of people whose creative work has inspired my creative juices to flow, is endless. I have gained immense knowledge about the different kinds of science writing in the literary world and I’m now more aware about my responsibilities as a science writer. I am discovering new ways to discharge these responsibilities with care and finesse. 

I have experimented with multiple blog formats over the course of this year and I am now beginning to understand where my future lies in the world of wildlife blogging. For this, I have my readers to thank. Your feedback has helped me find my voice – a voice that works for both you and me – a voice that hopefully works in favour of the wild we are working together to protect, preserve and promote. 

I’d also like to thank my family – my parents & sister – for their constant encouragement, without which I would never have had the courage to channel my passion into words. This blog is a source of comfort and joy to me today. Your critique and directions have helped me hone my writing and they challenge me to take on more challenging topics of discussion each day. 

Finally, I’d like to end by thanking everyone of my readers & followers for being with me on this exciting journey. I hope we can walk arm-in-arm for years to come, learning about the wild we all love so much. 

Have a great evening!

Lots of love,

5 Fun Facts About Sea Sponge

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: 

  1. 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.
  2. 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.
  3. 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!
  4. 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. 
  5. 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.

 

Bonus

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 the Top 5 most preferred sea sponge tampons

5 Beautiful Fungi From Around The World

Fungi are a group of organisms in the plant kingdom that include mushrooms, moulds and yeast. While some are plain-Jane in appearance, others look too beautiful to be real. But the fact is, they are real, they are beautiful and some are deadly. 

Here’s our list of 5 beautiful fungi from around the world:

Pixie’s Parasol Fungus

Found in Australia, New Zealand, Chile and New Celadonia, Mycena interrupa, aka, the Pixie’s Parasol grows on moist beech and eucalyptus trees. 

 

Fungi 1

5 Fun Facts About Rats

  1. April 4th is celebrated as World Rat Day. This day was chosen in honour of the date of incorporation of the Ratlist, a mailing list that’s dedicated to the care and upkeep of pet rats. 
  2. A rat’s whiskers are its “hearing” devices. The whiskers pick up vibrations from the ground and inform the rat the size of the object/creature coming towards it and the direction it is coming from.
  3. Rats have been observed making a high-pitched laughing noise when they play. 
  4. A rat’s teeth never stop growing. They can grow up to 5 inches per year. These teeth are so strong, they can gnaw through lead and aluminum sheeting!
  5. Rats have really good memories and can recognize faces & places. Their superb memory is one of the reasons why they don’t get lost in mazes and drain pipes. 

 

Bonus

In countries like Cambodia, Angola and Zimbabwe, Giant African rats are trained to detect landmines. In fact, these rats have saved countless lives through their super-rat landmine-detecting abilities. 

To qualify as a landmine-detector, the rats have to undergo a gruelling 6-9 months training and must pass an accreditation test. Read all about this interesting process here. You can also meet some of these heroes at Apopo

5 Fun Facts About Orchids

  1. There are more than 25,000 documented species of orchids in the world and they’ve been around since before the continental drift 200 million years ago.
  2. The smallest orchid in the world is in Ecuador. It is only 2.1mm long and it requires a microscope to examine. It’s petals are so thin and transparent, scientists believe they resemble the size and texture of human cells.
  3. There is an orchid called the Bee Orchid, whose petals and fragrance resemble a bee. The orchid uses its unique appearance and fragrance to attract male bees, to stimulate pollination.
  4. Orchid seeds are really tiny – smaller than a dust particle. That’s why some orchids take up to 15 years just to germinate. Many of the full-grown potted orchids found in stores are often decades old!
  5. Rare orchids can get really expensive. Some of the most expensive orchid plants are – Rotchschild’s orchid ($5,000 per plant), Fire lilies ($10-$20 per stem), Yellow And Purple Lady Slipper (Critically endangered – Priceless) and Ghost Orchid (Critically endangered – Priceless).

Bonus

That vanilla-flavoured ice cream you love so much? It’s derived from an orchid. The Vanilla planifolia is a type of orchid, whose leaves are used to derive the vanilla flavouring used in food and beverages. Additionally, when someone talks about “vanilla beans”, they’re actually referring to orchid seeds.

5 Fun Facts About African Wild Dogs

  1. Each African wild dog has a unique spotting/marking on its fur. These markings serve the same purpose as human fingerprints and help researchers and gamekeepers keep track of individual pack members.
  2. Unlike in other animal groups where males leave and females stay behind; male wild dogs stay in their birth pack for life, while females leave and join other packs after reaching sexual maturity. This ensures there is no inbreeding.
  3. African wild dogs follow a community-based rearing of their young. Every adult member of the pack is responsible for the safety & upbringing of the pups and both males and females share babysitting duties.
  4. Wild dogs packs are extremely loving and caring, often taking care of the injured members of their packs for years. Healthy, adult dogs give feeding priority to pups and injured pack members, even before feeding themselves.
  5. Wild dogs are extremely intelligent and plan hunts well in advance. In fact, it’s this intelligence, coupled with team work and endurance that makes them successful in 80% of all attempted hunts. In comparison, lions are successful only 17%-19% of the time.

 

Bonus

Humans have tried to domesticate wild dogs like they did other canids, but have remained unsuccessful. Why? Wild dogs have an inherent suspicion towards any animal apart from their own pack-members and they have an intense dislike towards being touched. All domesticated dog species on the other hand, were very friendly and liked being petted, even when wild.
