This study is focused on four otter species in Asia; the Eurasian Otter Lutra lutra, the Hairy-nosed Otter Lutra sumatrana, the Small-clawed Otter Aonyx cinereus and the Smooth-coated Otter Lutrogale perspicillata. The illegal wildlife trade poses a direct threat to all four species as they are popular for their fur and increasingly for their supposed qualities as pets. This study is an analysis of otter seizure data during the period 1980 to July 2015 inclusive.
