Maturity: Lm ? range ? - 24 cm
Max length : 58.0 cm TL オス/雌雄の選別がない; (Ref. 40637); 最大公表体重: 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.
