Another look at the goblin shark (Mitsukurina owstoni), a deep sea creature that's been sighted less that fifty times since its discovery. They're the only living representative of the family Mitsukurinidae.

Stargazer fish have their eyes situated on the tops of their heads and can bury themselves in the sediment with only their faces sticking out. Some species lure prey with a worm-shaped projection that comes out of their mouths. They are toxic and some can deliver a 50 volt shock!

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.

Meet the ribbon seal, native to the icy waters off the southern coast of Russia. With no confirmed predators (except humans who occasionally hunt them), these seals are known for being super relaxed, and will let you walk right up to them on the ice floes.

We know they kind of look and sound like a fancy dessert, but you won't find Little Egg Cowries on a dinner plate any time soon. In fact, you'll have a hard time finding them anywhere, because these spotty little sea creatures are masters of disguise. Through a process known as 'alimentary homochromy', they can change the colour, patterns, and shape of their flesh to perfectly mimic that of the coral and sea sponges around them.

A seagull on a glass roof looking really cute.

Seagulls are able to drink seawater to survive thanks to salt glands just above their eyes. These glands eliminate excess salt from the seawater and flush it out of the birds' nostrils in liquid form, an action that's often mistaken for a sneeze.

The cookie cutter shark (Isistius brasiliensis) is as fearless as they come! This small, 20-inch shark can take on giants like whales and larger sharks, and have even been known to mistakenly try to bite submarines. They dwell in the deep warm ocean and come closer to the surface as the sun sets to grab a quick snack off their unsuspecting prey. Cookie cutter sharks approach their victims from below, latch on with their suction cup style lips, bite and then twist (below). A nice, round hole is left as a souvenir. They get this easy meal by tricking other ocean residents with their distinctive brown collar, which may act as a lure that allows the cookie cutter shark to be seen as a smaller, not-so-scary fish. As frightening as they seem, the ...
