They tend to have exceptional eyesight and hearing abilities. By remarkably inhabiting most of the different habitats we see around us, mice have become one of the most successful species in the world.

Mice Interesting Facts

What type of animal are mice?

A mouse is a type of rodent. They are highly adaptable and found in almost every location throughout the world.

What class of animal do mice belong to?

Mice belong to the class Mammalia. They are members of the order Rodentia.

How many mice are there in the world?

Since mice are found throughout the world, their exact populations are not known. According to the International Union for Conservation of Nature or IUCN, most of the mouse species show stable population trends, while a few like the Calomys expulus (Caatinga vesper mouse) are increasing in number.

However, some species like Podomys floridanus (Florida mouse) and Sicista armenica (Armenian birch mouse) have decreasing population trends.

Where do mice live?

Mice are found throughout the world in various kinds of areas. Depending on the region, the mouse species tend to vary.

For instance, the field mice or wood mice (Apodemus sylvaticus) are commonly seen in Africa and North-Western parts of Europe. Kangaroo mice (belonging to the genus Microdipodops) are seen in the United States. Out of all the mice, one of the most commonly found species throughout the world is the common house mice.

What is a mouse's habitat?

Mice have been able to adapt to different kinds of areas, and hence, their habitats are quite diverse. For example, the common house mice are usually found in cosmopolitan areas, in houses, and near buildings.

They can also be found in open fields. These mice have also been able to inhabit tundra and desert areas.

Apart from the house mouse, the deer mouse (member of the Cricetidae family) is seen in regions like alpine habitat, grassland, woodland, dessert, and so on. The way these creatures have adapted themselves to different ecological surroundings is quite remarkable.

Who do mice live with?

Mice form organized groups with a definite social hierarchy. Generally, there is one alpha male mouse at the top of these groups. A group of mice is known as mischief. When kept as pets, mice live with humans as well.

How long do mice live?

Mice usually only live for one or two years in the wild. Hence, it can be said that the mice lifespan is quite short in the wild. However, in captivity, some species of mice, like the deer mice, can live as long as eight years.

Most live for about four to five years. The main threat faced by mice in the wild is a range of predators. Snakes, birds, cats, and even some arthropods, are among those that prey on mice.

How do they reproduce?

Mice are known for their high reproduction rate. This is made possible because the female mouse experiences an estrous cycle or a fertile period right after they give birth. Hence, they can produce several litters in a smaller time span.

Usually, their breeding takes place throughout the year. The gestation period for mice is 19-21 days. In spiny mice, there is a gestation period of about 39 days, following successful mating.

Each litter has six to eight baby mice. For a deer mouse, the gestation period is shorter and does not last for more than 31 days (in the case of lactating females) or 26 days (in the case of non-lactating females).

Once baby mice are born, they are fully dependent on their mother. In many species, the baby is born without eyes and cannot survive without their parent. They are weaned from their mother after around three weeks.

What is their conservation status?

Most of the mice belonging to several families, genera, and species are marked as Least Concern in the International Union for Conservation of Nature or IUCN Red List. However, a few species do face several threats to their population and hence, have been marked as Critically Endangered, Endangered, Vulnerable, or Near Threatened.

For instance, the Santiago Galapagos mouse has been enlisted as Vulnerable and the Perote deer mouse has been marked as Critically Endangered. Habitat loss poses a serious threat for the various mouse population.
