Fin's Fish Guide
The False cusk (Parabrotula plagiophthalma) is a saltwater fish of the family Parabrotulidae that grows up to 5 cm.
Description
The false cusk is a very small, flabby deep-sea fish of the family Parabrotulidae reaching about 5 cm. The elongate, jelly-like body is dark and has a continuous fin fringe in which the dorsal, tail and anal fins merge; true pelvic fins are absent. Unlike most brotulas, which live on the bottom, this species hovers in the open water of the deep sea worldwide, including the Atlantic, from the surface to several thousand metres. It feeds on small zooplankton. Notably, it is a livebearer, with internal fertilisation. Because of its small size and life in the deep open water it is rarely observed and has no fishery importance.
