Etymology: Carcharhinus: Greek, karcharos = sharpen + Greek, rhinos = nose (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated. Tropical; 5°S - 30°S
Length at first maturity / Size / Weight / Age
Maturity: Lm 91.0, range 85 - ? cm
Max length : 150 cm TL male/unsexed; (Ref. 244); 150.0 cm TL (female)
soft rays: 0. Grey or light brown above, white below; dorsal, caudal, and pectoral fins with black margins, expanded apically to black tips on caudal fin lobes and pectoral fins; probably a conspicuous white band on flank (Ref. 9997).
Western Pacific: southern New Guinea, Solomon Islands, and northern Australia (including Western Australia, Ref. 7300).
A little-known reef shark found in shallow water on the continental and insular shelves, but may range in deeper water (Ref. 244). Feeds on small fishes and crabs (Ref. 244). Viviparous (Ref. 50449). Rather skittish and timid when approached (Ref. 244). Probably harmless or minimally hazardous to people (Ref. 244). Utilized for human consumption (Ref. 9997).
Viviparous, placental (Ref. 50449). Size at birth between 35 and 39 cm (Ref. 244). Distinct pairing with embrace (Ref. 205).
