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.
Chiloé National Park
What feature made the island of Chiloe and Gulf of Corcovado as world-famous locations is the presence of local population of pygmy blue whales (The Cetacean Conservation Center carries out the Blue Whale Project). There are only 4 or more known forging grounds of them and blue whales in Southern Hemisphere including Chiloe region. In this area, it is notable that whales often enter into narrow fiords either to feed or rest. This area is also an important habitats for other whale species such as humpbacks, finbacks, seis, and possibly for critically endangered, only around 30 animals-remaining Peru/Chilean stock of southern right whales as well. Whales can also be observed close to shore in southern side of the island, such as near Caleta Zorra.
