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).

生态学
海洋 礁区鱼类; 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 / 年龄
Maturity: Lm 43.2, range 32 - 65 cm
Max length : 84.5 cm TL 雄鱼/尚未辨别雌雄; (Ref. 121648); 77.5 cm TL (female); 最大体重: 2.8 kg (Ref. 121648)
背棘 (总数): 0; 背的软条 (总数): 0; 臀棘 0; 臀鳍软条: 0. Position of anal fin origin well in front of second dorsal fin origin, long labial furrows, and short pectoral fins (Ref. 37816).
在第二背鳍鳍起源，长的唇沟与短胸鳍正前方的臀鳍起源的位置.(参考文献 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.
知道的很少岸边与外海的鲨鱼发现于大陆架与岛屿棚了.(参考文献 244) 发现到深度至少 36 公尺。 (参考文献 9997) 可能吃鱼，头足类动物与甲壳动物。 (参考文献 6871) 胎生的.(参考文献 50449) 生鲜使用与可能乾燥盐腌供人类消费.(参考文献 244) 也制成鱼浆.(参考文献 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)
