морской демерсальный; пределы глубины 0 - 200 m (Ref. 106604). Tropical; 43°N - 6°N, 103°E - 140°E

Длина при первой зрелости / Размер / Вес / Возраст
половая зрелость: Lm ?, range 103 - ? cm
Max length : 118 cm TL самец/пол неопределен; (Ref. 106604)
колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 0. Five to six dermal flaps below and in front of eyes; back with light areas between dark saddles marked with broad reticulated 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 bottom shark found inshore (Ref. 247); usually in sand or sandy mud bottoms (Ref. 11230); also on rocky and coral reefs (Ref. 43278). Nocturnal in habits (Ref. 247). Feeds on fish and presumably bottom invertebrates (Ref. 247), including lizardfishes, cutlassfish, horse mackerel and other jacks, goatfishes, groupers, tilefishes, sea robins, whiting, parrotfishes, sea bream, croakers, also skates, shark egg cases, cephalopods, and shrimp (Ref. 43278). Ovoviviparous (Ref. 43278, 50449), with up to 20 young in a litter (Ref. 247). Wobbegongs should be regarded as potentially dangerous because of its formidable dentition (Ref. 247, 13577). Used for human consumption (Ref. 247). Kept in aquaria in Japan and the United States (Ref. 43278).
Ovoviviparous, embryos feed solely on yolk (Ref. 50449). With up to 20 young in a litter (Ref. 247).
