Species overview
About the Northern Tamandua
The Northern Tamandua has pale fur crossed by a dark vest-like marking, a long narrow snout and a grasping tail. Strong curved foreclaws help it open insect nests and climb, while its long sticky tongue collects ants and termites.
This mostly solitary mammal uses trees and also travels on the ground. Its search for insects connects it to both forest branches and fallen wood. Mothers usually carry a single young on their backs. A tamandua’s defensive claws mean a quiet distant view is best for both animal and observer. Preserve nests, logs and vegetation instead of opening them to demonstrate how the animal feeds.
