Maturité: Lm ?  range ? - ? cm
Max length : 366 cm TL mâle / non sexé; (Ref. 90102); common length : 180 cm TL mâle / non sexé; (Ref. 90102)
Épines dorsales (Total) : 0; Épines anales: 0. Body with a reticular pattern of narrow dark lines (Ref. 13577). Caudal fin with its upper lobe hardly elevated above the body axis, with a strong terminal lobe and subterminal notch but no ventral lobe (Ref. 13577).
Body shape (shape guide): elongated.
A little-known shark (Ref. 247) found on the continental shelf and offshore reefs (Ref. 6871). Probably feeds on bottom fishes and invertebrates (Ref. 13577, 43278); also known to eat nocturnal teleost fishes such as squirrelfish and soldierfish (Holocentridae) and sweepers (Pempheridae) (Ref. 43278). Ovoviviparous (Ref. 50449). Might bite in self-defense or when mistaking a human foot for its usual prey (Ref. 247). Its tough skin sometimes used for leather (Ref. 13577). The maximum length of 366 cm TL reported for this species is uncertain (Ref. 247, 90102).
