简单描述
检索表 | 型态特徵 | 形态测量图
This species belong to the 'uarnacoides' complex, characterized by the following: lateral disc shape with pectoral fin apices broadly rounded rather than narrowly rounded or angular; color plain (usually uniform light to dark brown dorsally, and pale or whitish ventrally with or without a dark margin; a long and slender whiplike tail and platelike denticles in a broad dorsal band in adults. This species differs from H. hortlei in having a highly protrusible mouth and a pelvic girdle with prominent lateral prepelvic processes (Ref. 58327).
An inshore species which I s probably with restricted distribution in brackish habitats that are associated with runoff from large rivers. Feeds on small fishes and prawns. Males mature at ca. 49 cm WD, females at ca. 70 cm WD; born at ca. 19 cm WD (Ref. 114953). Female maturity based on a pregnant female; males apparently smaller than females; full term pup 18.4 cm DW (Ref. 58327).
