lesser marmoset rat
Hapalomys delacouri
Delacour's marmoset rat is a small arboreal rodent from Southeast Asia. It has soft fur, large eyes, and a long prehensile tail that helps it nimbly move along bamboo branches and trees.
Delacour's marmoset rat differs from most other rats by its fully arboreal lifestyle and prehensile tail. It is important for the forests of Indomalaya because it helps disperse plant seeds and serves as food for predators.
