Biology
Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Distinct pairing with embrace [17086]. Lays auger type eggs (about 12-18cm, 4.7-7 inches long) among rocks " kelp, often with more than female using same oviposition site, with as many eggs found in a single nest; female lay 2 eggs at a time, from spring to late summer in Japan, 6-12 times during a single spawning season. Eggs hatch in 1 year. Hatch at 18 cm (7 inches), max length at 1.2m (3.9 ft.). During courtship, male grasps pectoral fin of female " wraps posterior part of body under her so single clasper can be inserted into her cloaca. In several mating bouts observed, copulation lasted as long as 15 minutes [1658]. A common but little-known shark found on the continental and insular shelves in depths down to at least 50 m. Probably feeds on bottom invertebrates and small fishes [518]. In Japan, preferably near Nagasaki; inhabits rocky regions [17641]. A carnivore [17641]. Found in temperate waters where it frequents rocky reefs " kelp forests. Feeds on crustaceans, molluscs, small bony fishes, and sea urchins. Some specimens observed with hyrdroids growing in their teeth [1658].
