Длина при первой зрелости / Размер / Вес / Возраст
половая зрелость: Lm ?, range 43 - ? cm
Max length : 65.0 cm TL самец/пол неопределен; (Ref. 247)
колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 0. Genus: Nostrils subterminal on snout; pre-oral snout long, mouth closer to eyes than snout tip; eyes and supraorbital ridges hardly elevated; no black hood on head or large spot or spots on sides of body above pectoral fins (Ref. 43278). Caudal fin with a pronounced subterminal notch but without a ventral lobe (Ref. 13575).
Species: Light brown above, cream below, with numerous dark spots on body, tail, and fins, these often forming indistinct vertical bars and saddles (Ref. 31575). Dermal ridge on middle of back and two low lateral ridges (Ref. 4832).
Body shape (shape guide): elongated.
A common, but little-known inshore sluggish bottom shark (Ref. 13575) found on sandy and muddy bottoms of coastal waters, bays and inlets and rocky and coral reefs. Probably mainly feeds on bottom-dwelling invertebrates (Ref. 13575), also small fishes. Oviparous (Ref. 50449). Utilized for human consumption (Ref. 247). Possibly may occur in fresh water in the lower reaches of the Perak River in peninsular Malaysia (Ref. 43278).
