Mus musculus domesticus, commonly known as the house mouse, is a small rodent that belongs to the family Muridae. It is a subspecies of the species Mus musculus, which also includes wild mice. Mus musculus domesticus is the result of domestication, having been selectively bred over time for specific traits and characteristics.
The house mouse is characterized by its small size, typically measuring around 2 to 4 inches in length, excluding its tail, which can add an additional 2 to 4 inches. It has a pointed snout, round ears, and a slender body covered in short fur, usually light gray or brown in color, although variations can occur.
Mus musculus domesticus is highly adaptable and is found all over the world, often inhabiting human-made structures such as homes, buildings, and farms. It is a prolific breeder, with females capable of reproducing throughout the year, resulting in large populations.
House mice are primarily nocturnal creatures, being most active during the night. They are omnivorous, consuming a wide variety of food, including grains, seeds, fruits, and insects. Due to their diet and nesting habits, house mice are considered pests in many areas, often causing damage to crops, buildings, and stored food.
Historically, the house mouse has also been widely used in scientific research due to its physiological and genetic similarities to humans. As such, it has contributed vastly to our understanding of biology, medicine, and genetics.
