Stoat (Mustela erminea)

OTHER NAMES: Ermine, Short Tailed Weasel
Latin Etymology: Mustela ("weasel") erminea ("ermine")
Adult Stoat (subspecies A. a. stabilis) at Wooler, Northumbria - July 2009

Featured Subspecies: Mustela erminea stabilis
Weight: 260g  /  Length: 17-32cm
UK STATUS NOT EVALUTATED IUCN Red List: Least Concern

Possibly the easiest to see of the UKs seven mustelid species, it is still however, quite an unusual occurrence to see one. It looks superficially similar to the weasel, but can be told apart by the substantially larger size and black tip to its tail. As with many mustelids, it is proportionally an incredibly powerful predator - killing animals many times its size and weight such as rabbits.  The Stoat in the UK remains brown throughout the year, but in more northerly populations they grow a thick white coat for camoflage during Winter, and it is in this form they are known as ermine and have been hunted for their fur in the past.

Sea Otter (Enhydra lutris)

OTHER NAMES: N/A
Latin Etymology: Enhydra ("in water") lutris ("otter")

Sea Otter (subspecies E. l. nereis) at Monterey, California - September 2022

Featured Subspecies: Enhydra lutris nereis
Weight: 22-45kg  /  Length: 1.2-1.5cm
NO UK STATUS IUCN Red List: Endangered

Sea Otters are considered the smallest of all marine mammals, and live almost their entire lives in the water. Unlike most marine mammals however, this is allowed by the densest fur of any living animal which keep it warm. They feed on molluscs, which they bash open using a rock that they store in the pockets under their forearms. Heavily persecuted by the fur trade, sea otter numbers have partially begun to re-establish from their lowest point, but seem to have plateaued at lower levels than before.

Order: Carnivora
