Smooth-coated Otter

The smooth-coated otter (Lutrogale perspicillata) ranges from Pakistan, India and Nepal through southwestern China and Southeast Asia to Borneo, Sumatra and Java, with an isolated population in Iraq. The coat is short and smooth as the name suggests, and the tail is flattened with a triangular cross-section. Fish make up 75-100% of the diet, with insects, crustaceans, frogs and small mammals. It forms small family groups of a mated pair and up to four offspring from earlier seasons, unusually social for an otter. It is Vulnerable. Listed on CITES Appendix II from 1977, it was uplisted to Appendix I in 2019 and is designated an internationally endangered species under Japan's Act on Conservation of Endangered Species. Any transfer or sale within Japan therefore requires a registration certificate from the Ministry of the Environment, and unregistered trade is illegal. Husbandry demands a large permanent swimming pool and a fish-based diet of about 1 kg a day, so private keeping is extremely demanding. Only a very small number are kept in Japan.
