Carcharhinus tilstoni, Australian blacktip shark : fisheries
Elasmobranchii 板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) > Carcharhiniformes (Ground sharks) 白眼鮫目 (Ground sharks) > Carcharhinidae (Requiem sharks) 白眼鮫科 (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); tilstoni:In honor of Richard Tilston, naturalist-surgeon at Port Essignton, Northern Territory, near where holotype was collected in the 1840s (See ETYFish). Eponymy: Richard Tilston was a naturalist who trained as a physician at Guy’s Hospital, London (1841) and became a naval surgeon (1842). [...] (Ref. 128868), visit book page. More on author: Whitley.
Indo-West Pacific: currently known only from the continental shelf of tropical Australia. Very similar to Carcharhinus limbatus and reliably distinguished only by biochemical studies and vertebral counts (Ref. 9819). 印度-西太平洋: 現在已知只來自熱帶澳洲的大陸棚了。 非常類似 黑邊鰭白眼鮫〔Carcharhinus limbatus〕 與可靠的鑑別僅能藉由生物化學的研究與脊椎骨數。 (參考文獻 9819)
首次成熟时的长度 / 大小 / 重量 / 年龄
成熟度: Lm?, range 115 - ? cm Max length : 200 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9997); 最大体重: 52.0 kg (Ref. 6390); 最大年龄: 12 年 (Ref. 6390)
背棘 (总数) : 0; 臀棘: 0. Back dark grey, ashy blue or dusky bronze; belly white or yellowish white; a dark band extending rearward along each side to about over origin of pelvic fin; tips of pelvic fins with a persistent black spot (Ref. 9997). Body shape (shape guide): fusiform / normal. 背面深灰色的，灰蓝色或暗青铜色; 腹部白色或黄白色; 一个延伸的深色条纹向后沿着两边到大约腹鳍的起源上面; 腹鳍顶端具有一个持续的黑色斑点。 (参考文献 9997)
Found on the continental shelf from close inshore to about 150 m depth (Ref. 9997). Found throughout the water column but usually near the sea bed during the day and near the surface at night (Ref. 6390). Prefers teleost fishes but also feeds on cephalopods to a lesser degree. Viviparous (Ref. 50449). Forms large aggregations (Ref. 6871). Utilized for its meat and fins (Ref. 6871). The flesh has a relatively high mercury content (Ref. 6871).
Viviparous, placental (Ref. 50449). The average litter size is 3, with a range of 1-6, average total length at birth is 60 cm. Pups are born in January after a 10-month gestation period. These sharks breed once each year (Ref. 13440). Distinct pairing with embrace (Ref. 205).印度-西太平洋: 現在已知只來自熱帶澳洲的大陸棚了。 非常類似 黑邊鰭白眼鮫〔Carcharhinus limbatus〕 與可靠的鑑別僅能藉由生物化學的研究與脊椎骨數。 (參考文獻 9819)
