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.

生態學
海洋; 半鹹淡水; 深度上下限 0 - 150 m (Ref. 6871). 熱帶; 10°S - 28°S
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)
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 115 - ? cm
Max length : 200 cm TL 雄魚/尚未辨別雌雄; (Ref. 9997); 最大體重: 52.0 kg (Ref. 6390); 最大年齡: 12 年 (Ref. 6390)
背棘 (總數) : 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).
背面深灰色的﹐灰藍色或暗青銅色; 腹部白色或黃白色; 一個延伸的深色條紋向後沿著兩邊到大約腹鰭的起源上面; 腹鰭頂端具有一個持續的黑色斑點。 (參考文獻 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).
棲息於大陸棚了從岸邊到大約 150 公尺深.(參考文獻 9997) 在水團各處發現但是通常白天在海床附近與晚上接近水表面處.(參考文獻 6390) 偏愛硬骨魚也吃頭足類動物較少。 胎生的.(參考文獻 50449) 形成大群的魚群。 (參考文獻 6871) 用來做它的肉與鰭了。 (參考文獻 6871) 肉有一個相當高的水銀含量。 (參考文獻 6871)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
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)
