背面の脊椎 (合計) : 0; 肛門の骨: 0. A small shark with a short, bluntly rounded snout, oval eyes, and narrow-cusped teeth; 2nd dorsal fin large; no interdorsal ridge (Ref. 5578). Yellow-brown above, white below; all fins conspicuous with black or dark brown tips also anterior and posterior dark edging on pectoral fins and upper lobe of caudal fin; a prominent black tip of first dorsal fin set off abruptly by a light band below it; a conspicuous dark band on flanks, extending rearward to pelvic fins (Ref. 9997).

生物学     用語集 (例 epibenthic)

Inhabits shallow water close inshore on coral reefs and in the intertidal zone (reef flats), near reef drop-offs and close offshore (Ref. 244, 58302). Also found in mangrove areas, moving in and out with the tide (Ref. 6871) and even in fresh water, but not in tropical lakes and rivers far from the sea (Ref. 9997). Occurs singly or in small groups (Ref. 244, 54301). Prefers fishes but also feeds on crustaceans, cephalopods and other mollusks (Ref. 6871). Viviparous (Ref. 50449). May become aggressive to spear fishers and has been reported to bite people wading in shallow water (Ref. 6871). Reported to cause poisoning (Ref. 4690). 2 to 4 young of 46 to 52 cm are born per litter (Ref. 1602). Generally marketed fresh (as fillet), may be dried, salted, smoked (Ref. 5284) or frozen (Ref. 9987). Fins are valued for shark-fin soup (Ref. 9987); liver as source of oil (Ref. 9997). This species is commonly seen in public aquaria (Ref. 54301). Maximum reported weight from IGFA was 13.550 kg (Ref. 40637). Minimum depth reported taken from Ref. 128797.

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生

Viviparous, placental (Ref. 50449). Litter size 2-4 pups (Ref. 244) after an 8-9 months gestation period (up to 16 months in some localities) (Ref.58048). Size at birth ranges from 33-52 cm (Ref. 244); 48-50 cm TL (Ref.58048). Distinct pairing with embrace (Ref. 205). Precopulatory and courtship involve the male closely following near the female's vent which could possibly be guided by their sense of smell (Ref. 49562, 47987).
