This is a Horned Lizard: they shoot blood from their EYES.
That is a Dumbo Octopus: They are awesome and live way underwater to the darkest of depths. Beware of the dumbo Octopus.
Yeti Crab: Yes, its real. It's actually a lobster though. Its funny how scientists do that to confuse us. Remember when you thought Koala bears were bears? I do.
Hagfish: I actually found three of these wormlike fish at a beach. They dig into the ground for stuff and come back up even slimier than before. They actually blind prey with slime before killing them. Unfortunately I never actually saw that happen.
Axolotl: They are amphibians not fish. The reason they look the way they do is that they reach maturity at the larval stage. They do grow in size however. They can actually breathe through their skin. They have long external gills and only live in a specific lake.
But of course, everyone has a favorite: mine are Narwhals. The myth of unicorns is actually based off of people seeing their horns and making up unicorns to explain what they are (much like mermaids and manatees). Never upset the male Narwhal (they are the ones with large horns) he will shishkebab you before you can even say you pissed your pants. Anyway, they are the most awesome animal and deserve to me treated as such. This is a song is made of AWESOME. But WARNING it will be stuck in your head forever.
