Largest animal that has ever lived
|
view preview
Blue whales are not only the largest animal alive right now, but they are believed to be the largest animal that has ever lived. They are listed as endangered by the IUCN, but a group of researchers hopes to designate 10% of the ocean as protected by 2020. Despite their slow reproduction times, researchers believe this will be enough to help rebound their number

A fish that spits
|
view preview
Besides what we probably have seen while watching The Little Mermaid - fish singing and playing instruments, Finding Nemo, Shark Tale - whale being cleaned at a whale wash! , or even Spongebob Square pants - making hamburgers that is, have you ever seen or heard of a spitting fish? Well, I have not, until today.. Apparently, the archerfish from the family Toxotidea, literally "spit" to catch their prey. It is like a frog, but upgraded, in the sense that it catches insects and land based prey without a weapon, or a physical means. It just teleports its prey from above water, into the water by knocking it out via shooting water droplets. The missile strength of the water droplet is created and altered based on how far and how big their prey is ...

If Squidward were real
|
view preview
The Banded Piglet squid is proof that not all deep sea creatures are nightmare-inducing. They swim "upside down" compared to other squid, leaving him resembling a Muppet with his tentacles as the hair, the syphon as the nose, and his patterning appearing to be a smile. These guys live at least 100 m below the surface. Because of those incredible depths, it has to create its own light from the photophores underneath its eyes. Unfortunately, because it lives so far down, not much is known about its life cycle or eating habits. ...

Sea otters hold each others paws when they sleep
|
view preview
Since sea otters sleep at sea, floating around like in the video, holding hands like that keeps the group together, so they don't drift apart in the night. Because of this, the otters feel more comfortable holding hands while asleep than drifting alone. Therefore, it serves both social and practical purpose.

Which animal has the densest fur, try to guess
|
view preview
With up to one million hairs per square inch of its body, the sea otter has the densest fur in the animal kingdom. (To put this in perspective, you’ve probably only got 100,000 hairs or less on your whole head!) Together with a huge lung capacity, this makes these water-loving creatures extremely buoyant. The pups are born so buoyant, they're incapable of diving underwater, and are often left bobbing on the surface in a sea kelp bed while their mothers hunt for food nearby.

Some fish celebrate Halloween everyday
|
view preview
While we're talking about Halloween, this is the Atlantic wolffish ( Anarhichas lupus), very appropriately and otherwise known as the ‘devil fish’. The hefty fish grows up to 1.5 metres long and over 20kg, and they’re named for those unmistakable fangs. If they're not scary enough, their throats are also lined with a spattering of small, serrated teeth.
