Size / Weight / umur
Maturity: Lm ? range ? - ? cm
Max length : 76.0 cm TL jantan/; (Ref. 9710)
Edge of disk no sharp angles, no dorsal fin. Well-developed caudal fin extends around tip of tail, doubly serrate spine near caudal fin base (Ref. 26938). Disk yellowish, with dark vermiculations and spots that form a variety of patterns on upper surface (Ref. 7251). Lower surface is yellowish, greenish or brownish white, tail with dark spots (Ref.6902).
Commonly found along sandy beaches to the water's edge, and especially in sandy areas in and around coral reefs (Ref. 7251). Raises front end of disc to attract prey seeking shelter (Ref. 7251). Feeds on shrimps, probably also on small fishes, clams, and worms (Ref. 12951). Known to be capable of inflicting dangerous wounds with its venomous spine. Easily approached (Ref. 9710). A live-bearing species, produces 3 to 4 young (Ref. 26938).
Life cycle and mating behavior
Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | Larva
Male grasps disc margin of female, swings under her and inserts a clasper. Mating pair is surrounded by other males that swim around and nudge them. Dugger (1987) (Ref. 51118) observed both male and female biting the pectoral fin of its mate (Ref. 49562).
