Barathronus is a genus of deep-sea fish that are placed in the family Aphyonidae (blind cusk eels)[2][3] or family Bythitidae (brotulas),[1][4] depending on the source.

Life cycle

Barathronus are viviparous deep-sea fish. However, a juvenile Barathronus pacificus has been recorded in shallow waters.[5] Based on the stable oxygen isotope composition of otoliths, at least one species, Barathronus maculatus, has a pelagic larval stage, followed by an ontogenetic vertical migration to deeper waters.[6]
