What is an anglerfish?
Quick Answer
An anglerfish is a deep-sea predator that uses a glowing lure to attract prey. The lure is a modified spine tipped with light-producing bacteria in many species.
The Full Story
Anglerfish are famous for the fleshy lure, called an esca, hanging from the head like a fishing rod. In many deep-sea species, the light comes from symbiotic bacteria that live in the lure and produce bioluminescence. The lure helps the fish draw in curious prey in darkness, where food is scarce. Some anglerfish species also show extreme sexual dimorphism, with much smaller males in certain groups.
