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.

Meet the pistol shrimp. It is known to be the loudest animal and can emit a sound up to 200 decibels which it uses to stun its prey using its pincers. Check out the video below:

Without krill, most of the marine animals in Antarctica would disappear. So what are they?

Krill are crustaceans, each about 5 cm long. In addition to their diet of phytoplankton, they have the ability to scrape ice-algae from the underside of ice formations. In turn, they are on the menu for hungry squid, penguins, seals and whales. In short, krill form an integral part of the Antarctic ecosystem.

Together, krill would number in the billions, yet their numbers are decreasing. Why? One reason may be the melting and loss of ice formation due to increased global temperatures. Another reason is humans' greed. Krill oil, high in omega-3 fatty acids, is packaged as health medication to maintain healthy cholesterol. How many krill are worth the lif ...

The wolphin is the extraordinary result of breeding a female bottle-nosed dolphin with a male false killer whale. In captivity there are two occurrences, both are in the Sea Life Park in Hawaii. Unlike other hybrids, the wolphin is fertile.

Genetic testing of giant squid corpses discovered all over the world has found that not only are they all the same species, they have surprisingly low genetic diversity. This suggests that some time in the recent past they were pushed to the brink of extinction, but managed to rebound and are now found throughout the worlds oceans.
