Whale
The IWC has designated two whale sanctuaries: the Southern Ocean Whale Sanctuary, and the Indian Ocean Whale Sanctuary. The Southern Ocean whale sanctuary spans and envelopes Antarctica. The Indian Ocean whale sanctuary takes up all of the Indian Ocean south of 55°S. The IWC is a voluntary organization, with no treaty. Any nation may leave as they wish; the IWC cannot enforce any law it makes.
Perrin's beaked whale
This species has only been found off the coast of California between San Diego and Monterey. It likely lives off the Pacific coast of North America - and possibly elsewhere in the North Pacific - in waters 1,000 meters deep or more. However, evidence is lacking and the northern and southern limits of its range are entirely unknown (though biogeography of beaked whales suggests it does not reach the Equator). No population estimate or assessment of conservation status has hitherto been possible. San Clemente Island holds a sonar research facility of the US Navy; such research has in the past been implicated in causing strandings of cetaceans.
