Pronounced Ax-oh-lot-ul. Its scientific name is Ambystoma mexicanum (yup, its home country is Mexico). An axolotol is not a fish, but an amphibian, a salamander. You probably know it for being featured in hugely popular video games. Known as "the Peter Pan of animals", the axolotI retains its youthful larval appearance into adulthood, rather than undergoing typical metamorphosis.  Axolotis have the "superpower" of regenerating their organs and body parts. They can regenerate an entire limb when lost or even a spinal cord.

Scientific name: Grimpoteuthis. This is a small creature, generally around eight inches, that lives in extremely deep waters, where it's very cold and there is an absence of light. It has fins on its mantle that look like the huge ears of Dumbo the Disney elephant. The dumbo octopus is part of the group of "umbrella octopuses" which also includes the flapjack octopus. It feeds on snails, worms, and other creatures they hoover up from the ocean floor. Unlike most octopuses, the Dumbo octopus doesn't have an ink sac because it rarely encounters predators in the deep sea. Their main form of defense is camouflage. It is cute, and it knows it.

Scientific name: Psychrolutes marcidus. Well, ugly is in the eye of the beholder... The blobfish is a deep-sea fish of the family Psychrolutidae. It can be found in marine waters of the Atlantic, Indian and Pacific Oceans. Although on land it might have a body like Jell-O and a big old frown, things are different in its normal habitat (which is 2,000 to 4,000 feet underwater). There, the pressure makes the blobfish look like any ordinary fish. If you lived down that deep, you'd probably be squished into a flabby pile of sludge, too.
