Show Summary Details


This chapter discusses the internal anatomy, functional morphology, and luminescence of ceratioids, along with the biological significance of bioluminescence in these fishes. Specialized structures adapted to produce bioluminescence in ceratioids are restricted to females, the most conspicuous of these being the bait, or esca, located at the tip of the illicium. Other structures of females known or thought to luminesce include the esca-like bulb on the tip of the second dorsal-fin spine of diceratiids and ceratiids, the caruncles of ceratiids, and the jaw teeth, fin rays, dermal spines, and skin patches of various taxa.

Keywords: ceratioids; anglerfishes; internal anatomy; functional morphology; luminescence; esca
