Longueur à la première maturité / Taille / Poids / Âge
Maturité: Lm ?, range 43 - ? cm
Max length : 65.0 cm TL mâle / non sexé; (Ref. 247)
Épines dorsales (Total) : 0; Épines anales: 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).
Cycle de vie et comportement reproducteur
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
Oviparous, deposits eggs in small, oval egg cases on the bottom (Ref. 247). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205).
