Double anglers

Double anglers are a family, Diceratiidae, of anglerfish. They are found in deep, lightless waters of the Atlantic, Indian and western Pacific Oceans.

They are easily distinguished from other anglerfish by their possession of a second light-bearing dorsal fin spine immediately behind the illicium (the bioluminescent lure present in other anglerfish).

As in other anglerfish, males are very much smaller than the females and, after a larval and adolescent free-living stage, spend the rest of their life parasitically attached to a female.

Species in this family are known almost entirely from adolescent females: only two larvae, one adult female, and one adult male have been found.
