📖 Overview
Demersal species on continental shelf to at least 35 m (but likely to be deeper); also found in brackish water, with young collected from tide pools . Mobile invertebrate feeders, feeds on benthic mobile invertebrates such as molluscs, crustaceans and worms associated with hard or nearby unconsolidated substrate ; also on small fishes . Ovoviviparous . Marketed salted; also used in the preparation of gelatin and good quality oil. Between 1995 and 2000, at least 5 specimens have been traded as aquarium fish at Ceará, Brazil .
