Justification: Although wide-ranging and moderately common (where not heavily exploited), this shark is restricted to a limited inshore depth range in heavily fished temperate waters and is exposed to intensive inshore fisheries over most of its range. The central California stock in the San Francisco Bay area is thought to have been depleted in the early 1980s, but lack of fisheries data elsewhere make it impossible to determine whether this pattern of depletion occurs throughout its range. |
|
| Range Description: | Notorhynchus cepedianus is found in the southwestern Atlantic from southern Brazil to northern Argentina; southeastern Atlantic from Namibia and South Africa to the western Indian Ocean (India); western Pacific from southern Japan, the Koreas, China, and also Australia and New Zealand; and the eastern Pacific from British Columbia and Canada to southern California, the Gulf of California, Mexico, and from Peru to central Chile. |

| Habitat and Ecology: | This benthic marine species occurs in continental shelf areas. It is a coastal species, apparently coordinating its movements with tidal cycles, moving into shallow bay areas with the rising tide and back out to deeper areas with the tidal fall. It may sometimes be found in water less than one meter deep. A powerful predator with indiscriminate feeding habits, this shark is generally regarded as potentially dangerous to humans in open waters, particularly when provoked. |
| Systems: | Marine |
| Major Threat(s): | The species is subject to fishing pressures in several areas within its range. In California and in Australia it is the target for sport fishing and commercial fishing: the flesh of this species is sold for human consumption in these areas. In China, this shark is also caught for its skin, which is used for leather, and its liver oil which is used as a source of Vitamin A. |
