Laboratory Mouse


From nose to the tip of its tail this species is around 10cm long.

Habitat and Distribution
This mouse does not have a natural distribution because it is a hybrid between 2 subspecies of the common house mouse (Mus musculus domesticus x Mus musculus musculus).

The average lifespan of this mouse is 2 to 3 years however there is an event called the Methuselah Mouse Prize for extraordinarily long living mice. The current record is for a genetically engineered laboratory mouse which lived for 5 years.

This animal lives on a variety of fruits, seeds and nuts, but due to its captive life is generally fed on a commercially produced substitute of their natural diet.

Groups and Breeding
Once mating has occurred, the female will have a gestation of 19 to 24 days after which she can give birth to anything between 3 and 14 young). It is not uncommon for a female to be able to give birth to 10 litters per year.

This species has no threats.

Interesting facts
These mice were original selectively bred over a number of generations to result in all of them having essentially the same genetic structure making them perfect for laboratory work. They are so popular in laboratories due to a mixture of their ease of care, prolific breeding and their physiological and genetic similarities to humans.
