Due to its flat shape and coloration, the anglerfish among coral is difficult to distinguish as it rests on the seafloor.

Some anglerfish are also notable for extreme sexual dimorphism and sexual symbiosis of the small male with the much larger female, seen in the suborder Ceratioidei. In these species, males may be several orders of magnitude smaller than females.

Anglerfish occur worldwide. Some are pelagic (dwelling away from the sea floor), while others are benthic (dwelling close to the sea floor); some live in the deep sea  while others on the continental shelf.
