Aonyx cinereus
The world's smallest otter, using dexterous forepaws to eat shellfish and crustaceans and living in family groups. Listed on CITES Appendix I in 2019; in Japan only registered animals may be transferred.
The Asian small-clawed otter is the world's smallest otter, distributed from India, Bangladesh, Nepal and Bhutan through southern China, Myanmar, Thailand, Laos, Cambodia, Vietnam and Malaysia to Indonesia (Sumatra, Java, Borneo) and the Philippines (Palawan). As the name suggests the claws are small, and the dexterous, partly webbed forepaws are used to feel for prey. It feeds mainly on crustaceans, also taking molluscs, insects, fish and reptiles. It lives in family groups built around long-term pairs, up to about 15 animals in the wild, and can reach 15 years in captivity. The IUCN lists it as Vulnerable, with illegal trade for the Asian pet market among the main threats; 35 of 49 otters seized between 2015 and 2018 were reportedly bound for Japan, and in August 2019 the species was uplisted to CITES Appendix I. Appendix I species are designated internationally endangered under Japan's Act on Conservation of Endangered Species, and domestic transfer requires a registration certificate issued by the Japan Wildlife Research Center, so only registered animals can be sold legally and only a few change hands between licensed animal businesses. Keeping one requires a large pool and land area, group housing as a family, a diet including crustaceans, and management of strong odour and loud calls; it is not suited to ordinary households.
