Life cycle
editBarathronus 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]
