The pamthret, Vulpemusetla acer, is a large, predatory, carnivorous musteline mustelid unique to the coniferous forests of Eurasia and is one of the few carnivorans still in existence.

Its size (up to two metres in length) makes it by far the largest predatory animal found in the region and it probably owes its survival to its low, powerful build and its ability to run through the sparse undergrowth easily, bursting out suddenly upon its prey, like spine-tailed squirrels. Pamthrets live in small family groups and normally hunt in pairs.
