A sifaka – pronounced si-FAHK-ah — is a species of lemur, found only on the island of Madagascar. They’re known to jump from tree to tree and skip sideways on the ground.

The sifakas are mostly white on the head, body and tail with brown patches on the chest, arms and thighs. Their face is bare and black in color except for a small patch of white fur along the bridge of the nose.
