Issue
Earlier work included Aplochiton in the family Aplochitonidae. Aplochiton taeniatus is a specialized piscivore with a very large mouth and greatly enlarged teeth (McDowall and Nakaya 1988). Aplochiton marinus is considered a synonym of A. taeniatus. See McDowall (1971a) for a detailed description.
