The European mink, the scientific name Mustela lutreola, also referred to as the Russian mink and Eurasian mink is a semiaquatic species of mustelid native to Europe.
Minks don’t make good pets. Even if you happen to managed to undertake a pair of fur-farm rescues, they’d require the form of care and housing you’d give a zoo animal, together with a really giant door enclosure with a pool. In this article, I am going to talk about the European Mink habitat, population, skull, teeth, red mink, facts, eating, food web, etc.
European Mink Profile
European mink, Mustela lutreola is at present restricted to a handful of remoted populations in northern Spain/southwestern France, the Danube delta in Romania and Ukraine, and components of Russia.
Captive breeding programs have been established to facilitate ex situ conservation. In Estonia, a small breeding population has been established on Hiiumaa Island and there was a reintroduction in Saarland, Germany.
The essential present risk to European mink is competitors with the distantly-related, however invasive non-native American mink, following many years of sustained habitat loss and over-hunting. The European mink is classed as Critically Endangered on the IUCN Red List.
It is analogous in color to the American mink, however is barely smaller and has a much less specialized skull. Despite having an analogous name, construct, and behavior, the European mink isn’t carefully associated with the American mink, being a lot nearer to the European polecat and Siberian weasel (kolonok).
The European mink happens primarily by forest streams unlikely to freeze in winter. It primarily feeds on voles, frogs, fish, crustaceans, and bugs.
European Mink Range
The European mink, Mustela lutreola is usually restricted to Europe. Its range was widespread within the 19th century, with a distribution extending from northern Spain within the west to the river Ob (simply east of the Urals) within the east, and from the Archangelsk area within the north to the northern Caucasus within the south.
Over the final 150 years, although, it has severely declined by more than 90% and been extirpated or significantly lowered over most of its former range.
The present range consists of isolated inhabitants in northern Spain and western France, which is broadly disjunct from the principle range in Eastern Europe (Latvia, Estonia, Belarus, Ukraine, central areas of European Russia, the Danube Delta in Romania, and northwestern Bulgaria). It happens from sea level to 1,120 m (1,220 yd).
In Estonia, the European mink inhabitants have been efficiently re-established on the island of Hiiumaa, and there are plans for repeating the process on the close-by the island of Saaremaa.
European Mink Description
The European mink, Mustela lutreola has a big, broad head with quick ears. The limbs are quick, with comparatively well-developed membranes between the digits, significantly on the hind feet.
The mink’s tail is brief and doesn’t exceed half the animal’s body size (constituting about 40% of its size). The European mink’s skull is much less elongated than the kolonok’s, with more broadly spaced zygomatic arches and has a much less huge facial area.
In basic traits, the skull is intermediate in form between that of the Siberian weasel and the European polecat. Overall, the skull is much less specialized for carnivory than that of polecats and the American mink.
Males measure 373–430 mm (14.7–16.9 in) in body size, whereas females measure 352–400 mm (13.9–15.7 in). The tail size is 153–190 mm (6.0–7.5 in) in males and 150–180 mm (5.9–7.1 in).
Overall weight is 550–800 grams (1.21–1.76 lb). It is a quick and agile animal, which swims and dives skillfully. It is ready to run alongside stream beds, and keep underwater for one to 2 minutes. When swimming, it paddles with each of its front and back limbs concurrently.
European Mink Fur
The winter fur of the European mink, Mustela lutreola could be very thick and dense, however not long, and fairly loosely becoming. The underfur is especially dense in contrast with that of more land-based members of the genus Mustela.
The guard hairs are fairly coarse and lustrous, with very large contour hairs that are flat within the center, as is typical in aquatic mammals. The size of the hairs on the back and stomach differ little, an additional adaptation to the European mink’s semiaquatic lifestyle.
The summer season fur is considerably shorter, coarser, and less dense than the winter fur, although the variations are a lot lower than in purely terrestrial mustelids.
European Mink Coat
In darkish-colored people, the fur is darkish brown or virtually blackish-brown, whereas light people are reddish-brown. Fur color is evenly distributed over the entire body, although in just a few instances, the stomach is a bit lighter than the higher components.
In significantly darkish people, a darkish, broad dorsal belt is present. The limbs and tail are barely darker than the trunk. The face has no color pattern, although it’s higher and decrease lips and chin are pure white.
White markings may happen on the decrease floor of the neck and chest. Occasionally, color mutations reminiscent of albinos and white spots all through the pelage happen. The summer season fur is considerably lighter, and soiled in tone, with more reddish highlights.

Differences between European Mink and American mink
The European mink is much like the American mink, however with a number of essential variations. The tail is longer within the American species, virtually reaching half its body size.
The winter fur of the American mink is denser, longer, and more carefully becoming than that of the European mink. Unlike the European mink, which has white patches on each higher and decrease lips, the American mink virtually by no means has white marks on the higher lip.
The European mink’s skull is far much less specialized than the American species’ within the route of carnivory, bearing more childish options, reminiscent of a weaker dentition and fewer strongly developed projections. The European mink is reportedly much less efficient than the American species underwater.
The European mink has a varied diet consisting largely of aquatic and riparian fauna. Differences between its diet and that of the American mink are small. Voles are an important food source, carefully adopted by crustaceans, frogs, and water bugs.
Fish are an essential meal source in flood lands, with instances being recognized of European minks catching fish weighing 1–1.2 kg (2.2–2.6 lb). The European mink’s day-by-day meals requirement is 140–180 grams (4.9–6.Three oz). On occasions of food abundance, it caches its meals.
European Mink Behavior
The European mink doesn’t kind giant territories, probably because of the abundance of meals on the banks of small water our bodies.
The size of every territory varies in keeping with the provision of meals; in areas with water meadows with little meals, the house range is 60–100 hectares (150–250 acres), although it’s more regular for territories to be 12–14 hectares (30–35 acres).
Summer territories are smaller than winter territories. Along shorelines, the size of a house range varies from 250–2,000 m (270–2,190 yd), with a width of 50–60 m (55–66 yd).
The European mink has each an everlasting burrow and temporary shelter. The former is used all year besides throughout floods and is positioned no more than 6–10 m (6.6–10.9 yd) from the water’s edge.
The building of the burrow isn’t complex, typically consisting of 1 or two passages 8–10 cm (3.1–3.9 in) in diameter and 1.40–1.50 m (1.53–1.64 yd) in size, resulting in a nest chamber measuring 48 cm × 55 cm (19 in × 22 in).
Nesting chambers are lined with straw, moss, mouse wool, and bird feathers. It is more sedentary than the American mink and can confine itself for long intervals in its burrow in a very chilly climate.
European Mink Reproduction
During the mating season, the sexual organs of the feminine enlarge significantly and develop into pinkish-lilac in color, which is in distinction with the feminine American mink, whose organs don’t change. In the Moscow Zoo, estrus was noticed on 22–26 April, with copulation lasting from 15 minutes to an hour.
The mating season happens from February to March. The period of being pregnant is roughly 35-72 days, with births occurring in April and May. The variety of younger in a litter is between two and 7, however, normally the litter is around 4 or 5.
At birth, males are roughly 7.39 cm in total size and eight.4 grams and females are 7.19 cm and seven.6 grams. Young is in a position to open their eyes after Four weeks and the exterior auditory meati open inside 23 to 27 days.
Teeth seem within the younger inside 15-17 days and are changed by adult teeth by 60-72 days. Young are weaned at about 10 weeks, and start monitoring and capturing prey. The young start to disperse at about 2.5 to Four months. Females are polyestrous and obtain sexual maturity at about 1 year.
The average litter consists of three to seven kits. At birth, kits weigh about 6.5 grams (0.23 oz), and develop quickly, trebling their weight 10 days after beginning. They are born blind; the eyes open after 30–31 days.
The lactation interval lasts 2.0 to 2.5 months, although the kits eat stable meals after 20–25 days. They accompany the mom on searching expeditions on the age of 56–70 days and develop into unbiased on the age 70–84 days.
Mustela lutreola Predation
Predators of the European mink embrace the European polecat, the American mink, the golden eagle, giant owls, and the red fox. Red fox numbers have elevated significantly in areas the place the wolf and Eurasian lynx have been extirpated, in addition to areas the place modern forestry is practiced.
As red foxes are recognized to prey on mustelids, extreme fox predation on the European mink is a possible issue, although it’s unbelievable to have been a think about Finland, the place fox numbers have been low through the early 20th century.
Mustela lutreola Threat
The European mink (Mustela lutreola) is critically endangered and one of the threatened mammals in Europe. Once widespread throughout Europe, the European mink inhabitants have undergone an extreme decline and now occupy lower than 20% of its former range.
A current study reported that there are roughly 25,000 European minks in Russia, and the world total is lower than 30,000.
European Mink Conservation
Populations of Mustela lutreola have been in decline for ecological and business reasons. They are actually listed as endangered by the IUCN. The major purpose for inhabitants declines is business trapping for fur.
However, M. lutreola additionally suffers because of water air pollution, and hydroelectric constructions. The introduction of Mustela vison has additionally negatively impacted M. lutreola populations.
A current study reported that there are roughly 25,000 European minks in Russia, and the world total is lower than 30,000. Efforts to introduce M. lutreola within the Kuril Islands and Tajikistan have been initiated.
There are additionally roughly 2,000 M. lutreola present in France and roughly 1,000 in northern Spain. In a try to save lots of Mustela lutreola, British and Estonian biologists have established breeding inhabitants on an island within the Baltic Sea.
