Mus musculus (House Mouse)

Mus musculus, commonly known as the house mouse, is a small mammal native to Asia but now found worldwide, often living in human habitats. It has a slender body, large ears, and a pointed snout, typically weighing around 20 grams. Mice are highly adaptable, breeding rapidly, and feeding on a variety of foods. They play important roles in ecosystems as prey and seed dispersers, but they can also be pests, contaminating food and spreading disease. Used extensively in scientific research, the house mouse helps us understand genetics, medicine, and biology due to its genetic similarity to humans.
