sifaka

Sifakas (singular "sifaka"; ; ) are a genus (Propithecus) of lemur from the family Indriidae within the order Primates. The name of their 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.
