Tree shrew, small, squirrel-like arboreal insectivore (family Tupaiidae) with a pointed snout. Tree shrews were once thought to be primates, related to the lemurs, but they are now considered a group of their own. They live in trees and bushes from India and China to the Philippines and Borneo. Except for the pen-tailed tree shrew they come out by day, and most species live in family groups. They feed on leaves, fruit, and small animals. The babies are born in a nest of leaves, and the mother visits them every two days to feed them.
