The giant otter is the largest species of the Mustelidae family. It can measure from 1.5m to 1.8m and weigh 30kg. It used to inhabit almost all of South America, but was hunted indiscriminately for its silky skin, which fetched high prices in the fashion industry. It eats mainly fish, but can feed on other animals such as crab, reptiles, some birds and small mammals. It is an exceptional swimmer and has a powerful tail that helps propel its body. The giant otter only attacks when it feels threatened or has its territory invaded. It is a social animal that takes care of its young and other members of the group. The species featured in the video are two males called Ipixuna and Anauêra. The animals, which were rescued when they were still young in the Rio Negro, are being cared for by researchers from the National Institute for Amazonian Research, Inpa, which has its office in Manaus, the capital of Amazonas-Brazil.
