Local Malagasy people named sifakas after their unique call that sounds like shif-auk. These primates spend the majority of their time in the trees, but don't get around the way most lemurs do. Instead, they remain upright and leap quickly by jumping with their elongated hind legs. They can even clear distances of over 30 feet! To move on the ground, they do a two-legged sideways hop that is the cutest thing you've ever seen.
