Western Atlantic: southern Gulf of Mexico and West Indies to Santos, Brazil.
Inhabits shallow waters. Ovoviviparous (Ref. 50449). Mobile invertebrate feeders, feeds on benthic mobile invertebrates such as molluscs, crustaceans and worms associated with hard or nearby unconsolidated substrate (Ref. 103985). 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 (Ref. 49392).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205).
