Like something straight out of the movie Alien, a Singaporean fisherman found a live creature with dozens of arms wiggling and squirming on his boat, easily giving anyone the chills. What the fisherman caught is called a Basket Star, a close relative to the starfish. Its arms continue to grow, expand, and replicate, helping it catch prey.

An ancient species of fish that once swam with the dinosaurs, the Sea Lamprey is a jawless fish and looks a lot like an eel. Technically, they’re parasites and feed on the blood of their victims. So, basically, our worst nightmare.



RemoraSource: http://animaldiversity.org/accounts/Remora_remora/

A Remora, also known as a Shark Sucker, looks like someone stomped a boot on its head. But, that groove on their head is actually their sucking disc that they use to attach to sharks and other sea creatures to gain rides.


Malacosteus Niger

We don’t know exactly what this thing is, but we’re calling it a clear abomination if we’ve ever seen one. It was also caught by Roman Fedorstov, but we’re kind of wishing he’d never found it at all. It’s definitely going to haunt us for some time.

The Pacific Viperfish is one of those fish we wish we didn’t know existed. With massive teeth that they impale their victims with at high speeds, its not a fish to tangle with. Fortunately for humans, we rarely see these out in the wild as they swim deep in the ocean.
