Nelson's spiny pocket mouse is a small rodent with stiff fur covered in sharp spines. It lives only in the mountainous wet forests of southern Mexico and carries food in cheek pouches.
Nelson's spiny pocket mouse differs from other species with special sharp spines and a very small range in the Chiapas mountains. It is important for the forest because it spreads plant seeds and serves as food for predators.
