Lesser Egyptian jerboa

In the lesser Egyptian jerboa, females are larger than males, unlike many mammals; the source mentions no difference in colour between the sexes.

The lesser Egyptian jerboa is a small rodent with a rounded head, conspicuous eyes and ears, hind limbs much longer than the forelimbs for hopping, and three toes on each hind foot. Its tail is long and ends in a tuft of hair that helps with balance, and its back is darker than its belly.
