Definition

Noun: - Family Tupaiidae: A biological family comprising the tree shrews. These are small mammals native to the tropical forests of Southeast Asia. In some taxonomic classifications, tree shrews are placed within the order Scandentia, but they have also been historically considered to be prosimian primates due to certain anatomical similarities.
