AHHH!! As if you needed another scary thing living in the ocean. Boys and girls, meet the anglerfish. Lovley, eh?
They are bony fish named for the way they hunt their prey, where in a fleshy growth from the fish's head (the esca or illicium) acts as a lure. This is considered angling.
Some anglerfish are pelagic (live in the open water), others are benthic (bottom-dwelling). Some live in the deep sea and others on the continental shelf . They occur worldwide. You may remeber seeing him with one of our fishy friends in Disney/Pixar's FINDING NEMO.
The eggs of the anglerfish are wrapped around the dorsal fins which are specially hooked. These anglerfish species have few but large eggs and the hatchlings are also large and well developed.
Here are some pictures of anglerfish babies:
An anglerfish eats anything smaller and bigger than it. Almost nothing can eat an anglerfish. They attract prey by dangling a fleshy, bait-like appendage in front of their heads. The appendage resembles a fishing pole and is attached to the end of the forsal fin's spine.
