Muskrat, nutria, otter: characteristics and distinctive features from a beaver

Beginning hunters can not always determine who is in front of them: an otter, nutria or muskrat. And this is normal - the animals are actually similar. However, differences do exist. Which of these rodents is who, and will be described further.

What is the difference between muskrat and nutria and otter

Each of these representatives is a mammal that leads a semi-aquatic lifestyle. They are valued mainly for good fur, but in appearance and in the nature of their behavior they are completely different.

Did you know? Today, there are only 88–90 thousand otters on Earth. In the 18th century, their number was five times greater.

Nutria (literally translated from Spanish as otter) belongs to the Nutria family and is its only representative. Outwardly resembles a large rat. America is considered the birthplace of this animal.

Under the ice, the nutria practically loses its orientation: when it dives into the hole, it finds no return and dies.

Muskrat (musk rat) is a family of hamsters and is a rodent. Her genus is represented by one species. It differs from other rodents in large sizes. Initially, North America was considered the habitat, but in the twentieth century the animal was brought to Europe, where they perfectly took root and spread to Asia, taiga and forest-steppe.

Muskrat can swim back and forth.

The otter represents a squad of predators. It lives in fresh water. This animal, leading a mobile life, is found throughout Europe (except Switzerland and the Netherlands), Asia and North Africa.

Despite the fact that the otter lives in many places, it belongs to endangered species and is under state protection.

Special characteristics of animals

The behavior and lifestyle of these animals has both common qualities and differences.

OtterMuskratNutria
  • Life style semi-aquatic, nightly.
  • He is a clever fish hunter. It also moves quickly by land, hunched over a bit.
  • For living, he chooses deaf places inaccessible to civilization.
  • When kept in a cell, a cheerful, playful disposition is noted.
  • The otter is secretive and cautious, in open areas it never goes ashore.
  • Good eyesight. Moreover, animals are seen perfectly both on the shore and in the water. Turbid water is also not a hindrance - the otter finds a victim with vibrissae.
  • It leads mainly an aquatic lifestyle, often seen in thickets of herbs.
  • For housing, he builds holes and huts over land. Active around the clock, but show great activity at dusk.
  • A bold animal, if a person seems to him an enemy, can attack him.
  • He has a good ear - even with a little rustling, he is guarded and looked around. The slowness of the animal is only the first impression. In fact, nutria quickly jumps around. It is also worth mentioning that she quickly gets tired.
  • Swamp beaver (the animal got such a name for its lifestyle) has poor eyesight and sense of smell. Due to the specific structure of the organs of vision in the dark, they see better.
  • In the natural habitat, the animal’s active life begins at night. When breeding in captivity, activity is observed both day and night.
  • Nutria swims well and submerges under water. On hot days, she hides in the shade and avoids unnecessary mobility.
  • In natural conditions, it is not adapted for wintering in freezing reservoirs, does not build dwellings, does not make supplies.

All these animals are great swimmers. Therefore, if you decide to breed them at home, you should take care of a small reservoir in which the animals will splash. Otherwise, the quality of their fur will suffer greatly. Wild individuals need to be taken in infancy.

Otter Diet: Fish. But it can hunt crayfish, frogs, water rats. Sometimes birds and rodents can become victims. The animal can eat plant foods.

Mating otters usually occurs in spring (March - April), but in captivity they can mate all year. Pregnancy lasts 63 days. The brood is 2–4 puppies. Life expectancy up to 10 years.

In warm regions, this species can breed all year round, and in cold regions only in warm times (March - August). Pregnancy lasts 25-30 days. The litter contains 6–8 babies. Life expectancy of 5-10 years.
