Percival's spiny mouse

Percival's spiny mouse, Acomys percivali, is a rodent of the family Muridae found in Kenya, Somalia, South Sudan and Uganda. It lives mainly in the lowlands within the Great Rift Valley of Africa, up to about 1000 metres above sea level, especially in rocky areas covered with lava, and its natural habitats include dry savanna and dry shrubland. It is an insectivorous animal. Body length without the tail is 82 to 111 mm, the tail is 39 to 92 mm and body weight is 18 to 48 g. It was first described scientifically in 1911 by G. Dollman. With Acomys kempi it is one of two known mammals able to completely regenerate damaged tissue, including hair follicles, skin, sweat glands, fur and cartilage.
