What characteristic is common to the house mouse?

The house mouse is commonly characterized by having small eyes. This feature is part of its general morphology. The eyes of a house mouse are proportionately smaller compared to its body size, which reflects its adaptation to a nocturnal lifestyle. While they do have some sensitivity to light, their small eyes help limit exposure to bright environments, aiding their survival by allowing them to navigate effectively in low-light conditions where they are most active.

In addition, the house mouse is not known for having large eyes or colorful fur; its fur typically ranges from a grayish to brownish color, which provides excellent camouflage in its natural habitat. The characteristic of small eyes is consistent with their overall adaptations as a species that relies on sensory input other than vision, such as smell and touch, to detect predators and navigate their environment.
