Show Summary Details


This chapter discusses the seasonal distribution, vertical distribution; distribution relative to physical, chemical, and biological parameters; and geographical distribution of anglerfishes. Ceratioid anglerfishes are widely distributed in all the major marine faunal realms of the world between extremes of 70°N and 75°S. While most of the adults are restricted to lower mesopelagic and bathypelagic depths, those of some, for example Oneirodes carlsbergi, are concentrated at depths of only 300 or 400 m, while members of at least one genus (Thaumatichthys) have been captured off the bottom at depths in excess of 3600 m. At the same time, the eggs and larvae of all taxa are found in near-surface waters, thus the overall vertical and horizontal breadth of occurrence of these animals is truly vast. Taken by themselves, most of the 11 families and even some of the genera and species are almost as widespread as the full distribution of all species of the suborder combined.

Keywords: seasonal distribution; vertical distribution; ceratioids; anglerfishes; population distribution
