Etymology: Rhizoprionodon: rhiza (Gr.), root; prion (Gr.) saw; odon (Gr.), tooth, referring to teeth with serrated (saw-like) bases, or roots [replacement name for Rhizoprion Ogilby 1915, preoccupied by Rhizoprion Jourdan 1861 in mammals]. (See ETYFish); oligolinx: Per Springer, Greek for “short furrow,” referring to short upper labial furrow. (See ETYFish).

生態學
海洋 礁區魚類; 深度上下限 0 - 36 m (Ref. 9997). 熱帶; 30°N - 18°S
Indo-West Pacific: Persian Gulf east to Thailand, Indonesia, China, and Japan. Recorded from the Gulf of Carpentaria (Ref. 6871) and Palau (Ref. 244). This species is very close to Rhizoprionodon taylori, but is geographically separated from it (Ref. 244).
印度-西太平洋: 波斯灣東至泰國，印尼，中國與日本。 記錄自卡奔塔利亞灣 (參考文獻 6871) 與帛琉了。 (參考文獻 244) 這種是非常接近 Rhizoprionodon taylori, 但是地理性地從它另外區分出來.(參考文獻 244)
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 43.2, range 32 - 65 cm
Max length : 84.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 121648); 77.5 cm TL (female); 最大體重: 2.8 kg (Ref. 121648)
背棘 (總數): 0; 背的軟條 (總數): 0; 臀棘 0; 臀鰭軟條: 0. Position of anal fin origin well in front of second dorsal fin origin, long labial furrows, and short pectoral fins (Ref. 37816).
在第二背鰭鰭起源，長的唇溝與短胸鰭正前方的臀鰭起源的位置.(參考文獻 37816)
A little known inshore and offshore shark found on continental and insular shelves (Ref. 244). Found to depths of at least 36 m (Ref. 9997). Probably feeds on fishes, cephalopods, and crustaceans (Ref. 6871). Viviparous (Ref. 50449). Commonly caught by inshore demersal gillnet fisheries, especially off Java (Ref.58048). Utilized fresh and probably dried salted for human consumption (Ref. 244). Also used for fishmeal (Ref. 9997) and fins (Ref.58048). Minimum depth from Ref. 58018.
知道的很少岸邊與外海的鯊魚發現於大陸棚與島嶼棚了.(參考文獻 244) 發現到深度至少 36 公尺。 (參考文獻 9997) 可能吃魚，頭足類動物與甲殼動物。 (參考文獻 6871) 胎生的.(參考文獻 50449) 生鮮使用與可能乾燥鹽醃供人類消費.(參考文獻 244) 也製成魚漿.(參考文獻 9997)

Viviparous, placental (Ref. 50449). With 3 to 5 young per litter (Ref. 244, 37816). Size at birth 20-30 cm TL (Ref. 9997, 37816). Distinct pairing with embrace (Ref. 205).印度-西太平洋: 波斯灣東至泰國，印尼，中國與日本。 記錄自卡奔塔利亞灣 (參考文獻 6871) 與帛琉了。 (參考文獻 244) 這種是非常接近 Rhizoprionodon taylori, 但是地理性地從它另外區分出來.(參考文獻 244)
