Otters are semiaquatic members of the Mustelidae family, which also includes weasels, badgers, ferrets, and mink. The IUCN Mustelid and Viverrid Action Plan include the conservation of the entire family Mustelidae with the exception of the otter. Of the 13 otter species in the Lutrinae subfamily, the most recent edition of the IUCN Red List of Threatened Animals lists eight otters as ‘Vulnerable’ or without data.
