9) Vampire squid
While not as big as its cousin the giant squid, the vampire squid is much more fearsome…at least in name. The scientific name, Vampyroteuthis infernalis, suggests that it is not to be trifled with even though it only grows to about 6 inches in length. This animal’s namesake comes from the fact that it has spines covering its arms. It can also extend its tentacles to twice their normal length to capture prey or protect itself from predators. Its huge eyes (the largest per-body-mass of any known animal) allow it to stalk prey in the ocean’s depths. Not only does this squid glow, it can turn its glowing on and off, making itself invisible when it pleases in the dark depths. This squid is unique from others of its species because it has no ink sack and can swim extremely fast, darting in different directions to escape predators. These squid live as deep as 3000 feet.
10) Long-nosed Chimaera
Looking like a mix between a platypus and a streamlined jet, this deep-sea creature looks like a failed genetic experiment. Known in scientific circles as the Harriotta raleighana, this creature sports a poisonous barb that has venom lethal enough to kill a human. These creatures can grow to 5 feet long and lives at depths of 8,000 feet.
