They were not a true marine species but were semi-aquatic animals, preferring to live in coastal environments, mainly rocky coasts or offshore islands. Low numbers of surviving young would have contributed to the sea mink’s inability to survive pressure from the fur trade. Litters were five to ten and stayed with their mother until 13 or 14 weeks old; however, the steps to independence and establishing a territory was usually beset with dangers and a high level of mortality. [8][13][16] One study looking at the remains in shell middens in Penobscot Bay reported that sea mink craniums were intact, more so than that of other animals found, implying that they were specifically placed there. The sea mink produced a distinctive fishy odor, and had fur that was said to be coarser and redder than that of the American mink. 4 Mink Facts. [13], Fur traders who hunted it gave the sea mink various names, including water marten, red otter, and fisher cat. Other than a chipped canine, all the teeth are in good condition. The nasal bone has an abrupter ascension, and the carnassial teeth make a more acute angle with the gums than those of the common mink (N. v. Prentiss based his description on skull fragments recovered from Native American shell middens in New England. In fact, the justification for it being its own species is the size difference between it and the American mink." [9] Since almost all members of the subfamily Mustelinae exhibit sexual dimorphism, male sea minks were probably larger than female sea minks. [4], The taxonomy of the minks was revised in 2000, resulting in the formation of a new genus, Neovison, which includes only the sea mink and the American mink. This advert is located in and around Canvey Island, Essex. They would mark territory along a shoreline with specific scents. Their body was flatter than that of the American mink. The sea mink (Neovison macrodon) is a recently extinct species of mink that lived on the eastern coast of North America around the Gulf of Maine on the New England seaboard. At least one species was driven to extinction by fur hunters, the sea mink. The specimen is apparently larger than the Alaskan mink (N. v. nesolestes), as the average distance between the last incisor to the first molar is 2.8 centimeters (1.1 in) in the Alaskan mink, whereas that distance is 3 centimeters (1.2 in) in the type specimen. [4][13][20] In 1929, Ernest Thompson Seton, a wildlife artist, concluded that the probable dimensions for this animal are 91.4 centimeters (36 in) from head to tail, with the tail being 25.4 centimeters (10 in) long. The extinct sea mink is related to the American mink but was much larger. Size: Mink are about the same size as ferrets, which makes them significantly smaller than otters, with a length of 30-45cm and a tail of 15-25cm on top. Their body was flatter in comparison to the American mink. Although not a truly marine species, being confined to coastal waters, the sea mink was unusually aquatic compared to other members of Musteloidea, being, next to otters, the most aquatic member of the taxon. Minks’ webbed feet and fur are covered with an oily substance which prevents their skin from being soaked. [16] Mead concluded that only American minks inhabited the mainland and that sea minks were restricted to islands off the coast. [13], The type specimen was collected by Prentiss and Frederick True, a biologist, in 1897 in Brooklin, Maine, the remains of which consist of a maxilla, parts of the nasal bone, and the palate. Mink is by far the most popular farmed fur, and Chinese minks dominate the market. [4], Since the sea mink has only been described by fragmentary remains, its appearance and behaviors are not well-documented. [13][15], The sea mink was a marine mammal that lived around the rocky coasts of New England and the southernmost Maritime Provinces until it was hunted to extinction in the late 19th or early 20th century. Formerly, both minks were classified in the genus Mustela. The last two recorded kills of a sea mink were made in Maine in 1880 near Jonesport, Maine, and Campobello Island, New Brunswick, in 1894,[14] although the 1894 kill is speculated to be of large American minks. It’s an important animal for the fur industry. The sea mink produced a distinctive fishy odor, and had fur that was said to be coarser and redder than that of the American mink. The last went extinct in the early 20th century because of the fur trade. However, they were known to be solitary and territorial. The project aimed to: 1. eradicate American mink entirely from the Outer Hebrides 2. continue to monitor North and South Uist for mink activity 3. collect data on effective control methods 4. assess the effects of mink control methods 5. promote awareness of bird conservation and the international importance of the Western Isles, including the risks posed by mink We continue to share our findings with other European countries facing similar problems, including Poland, Norway, Spain, France and Iceland.
