Deceptive Sizing: 3 Newborn Animals Who Are Ridiculously Smaller Than Their Parents

Ah baby animals…these bundles of joy have been lighting up the wild for millennia. While everyone has been raving about their cuteness, not a lot of people have spoken about their size. Let’s face it, when it comes to size, some animals are impressive…impressively small. 

Here are 3 animals whose babies are way smaller than you thought they would be: 

 

Kangaroos

Kangaroo adults can reach heights of 5.25 feet (1.6 meters) and can weigh 90 kilograms (200lbs). But their newborn joeys are smaller than gummy bears, often smaller than 25 millimeters. 

 

 

Watch the incredible journey this little joey makes to reach the safety of its mother’s pouch:

 

 

Pandas

At their heaviest, adult pandas can weigh 160 kilograms (350 lbs). But their tiny cubs weigh only 1/900th of their mother’s weight! Now that’s really tiny. 

 

Panda 2

See that little pink floppy thing on the left side? yup, that little nugget is the cub.

Here’s a fun question; what do you call a group of pandas? An embarrassment! Ha ha, all jokes aside, a group of pandas is called “an embarrassment” because of the boisterous way in which panda cubs play when they’re together. It could embarrass any mum. 

Now indulge in some cub time by watching twin panda cubs embark on their first 100 days of life. 

 

 

Elephants

One of the most intelligent animals on the planet, elephants have longest gestation period in the wild. It takes their bodies 22 months to fully develop the calf (imagine being pregnant for almost two years!). But surprisingly, baby elephants when born are only 90 kilograms (200 lbs), while their heavy-weight mothers, aunts and sisters (and not to forget, their brothers and fathers) can reach ridiculously high weights of 3600 kilograms (4 tonnes)! 

 

 

Watch as this newborn calf, just hours old, meets his herd-mates, learns how slopes are not a baby’s friend and discovers the forest he is to grow up in.

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 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

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
