Calomyscidae – Mouse-like hamsters

The family of small mouse-like hamsters that are found in n Pakistan, Afghanistan, Iran, Syria, Azerbaijan, and Turkmenistan

They are small and mouselike in overall appearance, hence the family’s common name. The tail is at least as long as the head and body combined, and the ears are large and prominent. The fur is fine and soft, while the top of the tail is dark, and the underside is white.

These animals are active all year round. In summer, they become strictly nocturnal, but in the fall and winter, they are active at any time of the day or night. They are very good climbers but never forage far from a rock crevice so that they can seek shelter quickly as soon as they sense the danger.
