Verreaux's sifaka lemur. Lemurs are close relatives of monkeys and other primates, that can only be found on the island of Madagascar. There are over 100 separate species of lemur in Madagascar, and most are highly specialized, allowing multiple species of lemur to live alongside each other without competing for the same food.
The Verraux's sifaka is mainly arboreal, and is so well adapted to jumping from limb to limb, that it is unable to walk on land. Instead it hops along on its hind legs until it can get back into the forest canopy.
This lemur is considered to be endangered, with a quickly shrinking habitat. We spotted this one sitting on the trail at Islao National Park, Madagascar.
