Land Shark!

Actually, land catfish. Scientists have been studying an African eel catfish that can move about on land and capture small insects.

These particular eel catfish, Channallabes apus, live in tropical swamps in Africa, where most of the water is confined to small, acidic pools.

"There's probably more food traveling on land than in these small puddles of mud," said Sam Van Wassenbergh of the University of Antwerp in Belgium. "That's probably why this fish has specialized to go out of water to search for food."

The catfish pick up speed in water and flop onto land, where their flexible vertebral column lets them move around like a snake. They also have a special organ for breathing air without using their gills, although scientists don't quite know how this works.
