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.
Short-finned pilot whale
Short-finned pilot whales, unlike the related long-finned pilot whale, are found in most waters around the world. They primarily inhabit warm tropical waters, but usually stay offshore in the deeper waters. They also tend to be found in areas with a high density of squid. Known populations are found in the North Atlantic stretching all the way south to northern South America, including the Gulf of Mexico and to Africa, as well. They are thought to migrate south into the western North Atlantic in the late winter/early spring. Other populations are recorded throughout the entire Pacific stretching from Japan to southern Guatemala, as well as the Red Sea and Indian Ocean.
