STATUS: Invasive, “Least Concern”

DESCRIPTION: They are 3-4 inches long and weigh 1.4- 1.6 oz. They have light brown fur and a tail that is used for balance.

DIET: Plants and insects. They eat their own feces to get nutrients produced by basteria in their intestines.

HABITAT: While it is originally a wild mouse, it has grown to be very well adapted to human areas and is more often found in buildings than outside.

NOTES: It has been domesticated as a pet and lab mouse. Its work as a lab mouse has made it one of the most important model organisms in biology and medicine. The complete mouse genome was sequenced in 2002. They are good climbers, jumpers, and swimmers.
