Found in bays, in sea grass beds, kelp beds, and near reefs on sand and mud bottoms (Ref. 12951). Digs in the sand to feed (Ref. 5227). Feeds on small fishes, crabs, clams, and other benthic invertebrates (Ref. 37955). Ovoviviparous (Ref. 50449). Venomous spine on tail.

Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
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).
