Size / Weight / Age

Maturity: L_m ? range ? - 24 cm
Max length : 58.0 cm TL male/unsexed; (Ref. 40637); max. published weight: 1.4 kg (Ref. 4699)

Occurs on sand, rubbly or mud bottom off beaches and in bays and sloughs; near seagrasses, usually shallower than 15 m. Adult females profuce 2 litters of up to 6 pups per year (Ref. 2850, 114953), sometimes around rocky reefs (Ref. 12951). Feeds on benthic invertebrates and small fishes.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Male grasps disc margin of female, flips under her, and inserts a clasper. Mating lasts about 5 minutes.
