This includes five endemic primates: the Mentawai or kloss gibbon (Hylobates klossii), Mentawai macaque (Macaca pagensis), Siberut macaque (Macaca siberu), Mentawai leaf monkey (Presbytis potenziani), and pig-tailed langur (Simias concolor). They are highly endangered due to logging, unsustainable hunting, and conversion of rainforest to palm oil plantations. Some areas of the Mentawai Islands rain forest ecoregion are protected, such as the Siberut National Park. Red junglefowl, the Asian Palm Civetand crab-eating macaque are also native.

 

Seismic activity
The Mentawai Islands lie above the Sunda megathrust, a seismically active zone responsible for many great earthquakes. This megathrust runs along the southwestern side of Sumatra island, forming the interface between the Eurasian Plate and Indo-Australian Plate.

Earthquake and tsunami activity has been high since the 2004 Indian Ocean earthquake. In 1833, the region was hit with an earthquake, possibly similar in size to the 2004 Indian Ocean earthquake, another large earthquake struck in 1797. On October 25, 2010, an earthquake in southern Sumatra led to a deadly tsunami that devastated villages in South and North Pagai.
