Brief Summary

provided by FAO species catalogs
A little-known temperate to tropical inshore bottom shark, found on rocky and coral reefs. A nocturnal shark, rarely observed by divers. Ovoviviparous, with litters of up to 20 to 23 young. In captivity in an aquarium in Okinawa, Japan, gives birth in spring (March through May), and has been observed in courtship. The male grabs the female in the gill area while mating with her. The gestation period is about a year. Eats primarily benthic fish, including lizardfishes (Synodontidae), cutlassfish (Trichiuridae), horse mackerel and other jacks (Carangidae), goatfishes (Mullidae), groupers (Serranidae), tilefishes (Malacanthidae), sea robins (Triglidae), whiting (Sillaginidae), parrotfishes (Scaridae), sea bream (Sparidae), croakers (Sciaenidae), also skates (Rajidae), shark egg-cases, cephalopods, and shrimp.

Diagnostic Description

provided by FAO species catalogs
fieldmarks: Flattened benthic sharks with dermal lobes on sides of head, symphysial groove on chin, very conspicuous variegated colour pattern of broad dark dorsal saddles with light spots and corrugated edges, interspaced with light areas with dark broad reticular lines; also, mouth in front of eyes, long, basally branched nasal barbels, nasoral grooves and circumnarial grooves, two rows of enlarged fang-like teeth in upper jaw and three in lower jaw; first dorsal-fin origin over pelvic-fin bases. Nasal barbels with a few branches. Five dermal lobes below and in front of eye on each side of head; dermal lobes behind spiracles branched and broad. No dermal tubercles or ridges on back. Interspace between dorsal fins longer than inner margin of first dorsal fin, about half first dorsal-fin base. Origin of first dorsal fin behind midbases of pelvic fins. First dorsal-fin height about equal to base length. Colour pattern highly variegated and conspicuous, dorsal surface of body with conspicuous broad, dark rectangular saddles with deeply corrugated margins, dotted with light spots and not ocellate in appearance; interspaces between saddles light, with numerous broad reticulated lines.

Biology

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).

Japanese wobbegong

provided by wikipedia EN

The Japanese wobbegong (Orectolobus japonicus) is a carpet shark in the family Orectolobidae of the wobbegong family, found in the tropical western Pacific Ocean from Japan and Korea to Viet Nam and the Philippines, between latitudes 43 and 6°N. It reaches a length of 1 m. Japanese wobbegong sharks typically remain motionless during the daytime, and are not active hunters. They use camouflage and their electroreceptor pores on their dorsal area to help them sense prey nearby.
