Sifaka

Sifakas (singular "sifaka"; i/ʃɪˈfɑːk/; ) are a genus (Propithecus) of lemur from the family Indriidae within the order Primates. Their name of the family is an onomatopoeia of their characteristic "shi-fak" alarm call. Like all lemurs, they are found only on the island of Madagascar. All species of sifakas are threatened, ranging from vulnerable to critically endangered.
