Length at first maturity / Μέγεθος / Βάρος / Age
Maturity: Lm ?, range 43 - ? cm
Max length : 65.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 247)
Ραχιαίες άκανθες (συνολικά) : 0; Εδρικές άκανθες: 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).
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).
Life cycle and mating behavior
Maturities | Αναπαραγωγή | Spawnings | Egg(s) | Fecundities | Προνύμφες
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).
