The Angler Fish also fishes for its prey, this time with help from bioluminescent bacteria. The Wall Street Journal reports:

"A spine of the fish's dorsal fin has evolved to stick out like a fishing rod; its tip is home to a colony of bioluminescent bacteria. Attracted by the glowing lure, prey swim towards the angler fish and are devoured in its toothy jaws."

This 'angling' gives the Angler fish membership to the order of Lophiiformes -- savvy fish which use fleshy growth to lure prey.
