板鰓亜鋼(サメとエイ類) (sharks and rays) >
Carcharhiniformes (Ground sharks) >
Carcharhinidae (Requiem sharks)
Etymology: Carcharhinus: karcharos (Gr.), sharp or jagged; rhinus, an ancient name for sharks, from rhine (Gr.), rasp, both words alluding to a shark's jagged, rasp-like skin (See ETYFish); cautus: Latin for nervous or wary, the “Nervous Shark” mentioned in Whitley (1940), referring to how the “slightest splashing” in shallow water caused this shark to “dash away at great speed into deep water” (See ETYFish).

海 関連する礁; 深さの範囲 0 - 20 m (Ref. 106604). Tropical; 5°S - 30°S
Western Pacific: southern New Guinea, Solomon Islands, and northern Australia (including Western Australia, Ref. 7300).
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 91.0, range 85 - ? cm
Max length : 150 cm TL オス/雌雄の選別がない; (Ref. 244); 150.0 cm TL (female)
背面の脊椎 (合計) : 0; 肛門の骨: 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).
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).
