Though it sounds like something out of a horror movie, it's true: there are squid capable of leaping out of the water and flying.

 

One species is the Humboldt squid, a large, jumbo-sized animal known to be aggressive toward humans, though if you see one flying it's likely to be escaping from a predator rather than acting like one.

 

Flying squid accomplish flight much in the same way as flying fish, only they use their mantle fins as wings. Some flying squid have even been seen jetting water out of their funnels to create propulsion while in the air.
