Description

The Sea Mink was about twice the size of the common or American Mink (Mustela vison), but had similar reddish-brown fur, slightly bushy tail and distinctive odour. It was not identified as a distinct species until after it had been exterminated.

Top

Distribution and Population

The exact range which was once occupied by the Sea Mink is not known, but it is believed to have extended at least from Connecticut to the Bay of Fundy, and possibly Newfoundland. There is no information on the size of former populations of the Sea Mink.

Top

Habitat

The Sea Mink preferred coastal habitats, particularly rocky coasts and offshore islands.

Top

Biology

Very little is known about the biology of the Sea Mink. Existing information suggests that these mammals were solitary and nocturnal, and spent most of their time at sea.

Top

Reasons for extinction

Extermination of the Sea Mink was caused by overhunting for the fur trade. The last specimen was taken at Campobello Island, New Brunswick, about 1894.
