一種小的種與下列的鑑別特徵: 尖銳的吻, 角少於 110個 °, 對尖頂涵蓋有增大的細齒; 體盤長度 94-101% WD; 頭長 47-51% WD; 口前長度 21-25% WD; 鼻孔 9-11% WD 之間的距離; 第一個鰓縫 20-25% WD 之間的距離; 尾部中等側扁上方腹皮膚的摺層的基部中央, 寬度 0.7-0.9 倍於它的高度; 腹的摺層細長的, 它的長度 1.1-1.3 倍 WD ， 32-41 在它的基部中央之下倍於它的深度; 在它的基部中央的倍尾部高度的腹摺層深度 1.8-2.4; 從泄殖腔到刺 0.9-1 在 precloacal 長度的距離; 1-3個頸背的刺, 大的珍珠-形狀的; 胸鰭動脈 113-120; monospondylous 椎骨的中心 35-38.(參考文獻 58027)
Found most abundant near the coast in regions of high riverine outflow. Largest immature male was found to be 27.5 cm WD. No data on size at birth, with smallest specimen 13.2 cm WD of a late male embryo (Ref. 58027). Data for Max.Length of female from Ref.58027. Caught occasionally by bottom trawl and demersal gillnet fisheries operating off Sumatra and Kalimantan. Utilized for its meat and probably its skin (Ref.58048).
