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). 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: Young and adults with transverse dark bands and numerous white or bluish spots (Ref. 13575, 43278). Body with lateral dermal ridges (Ref. 43278, 13575).
A common but little-known inshore bottom shark (Ref. 247); found on rocks and coral reefs (Ref. 90102). Feeds on bony fishes and crustaceans (Ref. 43278). Oviparous (Ref. 43278, 50449). Utilized for human consumption (Ref. 247) and used in Chinese medicine (Ref. 12166). Caught by multiple hook and line and trawl (Ref. 47736). Caught rarely by demersal gillnet fisheries operating inshore (Ref.58048).
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Hatches at 10-13 cm TL. In Taiwan, hatching occurs in June to August (Ref.58048).
