The treeshrews are small mammals native to the tropical forests of South and Southeast Asia. They make up the entire order Scandentia, which split into two families: the Tupaiidae, and the Ptilocercidae.
The Nicobar Islands rain forests is a tropical moist broadleaf forest ecoregion in the Nicobar Islands. The Nicobar Islands are in the Indian Ocean, lying north of Sumatra and south of the Andaman Islands. The islands are politically part of India, although physically closer to Southeast Asia. Millions of years of isolation from the mainland has given rise to a distinct flora and fauna, including many endemic species.
The common treeshrew is a small mammal in the treeshrew family Tupaiidae, and is native to Thailand, Malaysia, and Indonesia. It has been listed as Least Concern by IUCN as it remains common and displays some adaptability to ongoing habitat loss.
The golden-bellied treeshrew is a treeshrew species within the Tupaiidae. It is also called Mentawai treeshrew as it is endemic to the Indonesian Mentawai islands of Sipora, North and South Pagai. It lives in forests, and is considered endangered due to habitat loss since the islands' forests are continuously logged.
Horsfield's treeshrew, also called Javan treeshrew, is a treeshrew species within the Tupaiidae. It is endemic to the Indonesian islands of Sumatra, Bali, Java and Nias where it inhabits foremost primary forest.
The long-footed treeshrew is a treeshrew species within the Tupaiidae. It is endemic to Borneo and threatened due to deforestation and degradation of habitat.
The mountain treeshrew is a treeshrew species within the Tupaiidae. It is endemic to Borneo and inhabits montane forests in Sarawak and Sabah, Malaysia, and Kalimantan, Indonesia.
The Palawan treeshrew is a treeshrew species endemic to the Palawan Island, Philippines, where it occurs from sea level to an elevation of 1,400 m (4,600 ft). The population is considered steady. Formerly, it was considered a subspecies of the common treeshrew.
The painted treeshrew is a treeshrew species of the family Tupaiidae.
The ruddy treeshrew is a treeshrew species in the family Tupaiidae. It is endemic to Borneo, the Natuna Islands and the Anambas Islands.
The large treeshrew is a treeshrew species within the Tupaiidae. It is native to Sumatra and adjacent small islands, as well as in the lowlands and hills of Borneo.
The Nicobar shrew or Nicobar white-tailed shrew is a critically endangered species of mammal in the family Soricidae. It is endemic to Great Nicobar Island in India.
The Mindanao treeshrew, also called the Philippine tree shrew, is a species of treeshrew endemic to the Mindanao region in the Philippines. It was formerly considered the only member of the genus Urogale, but that genus was merged into Tupaia when the species was found to nest within the latter genus in a molecular phylogeny. The scientific name commemorates British colonial administrator and zoological collector Alfred Hart Everett.
Tupaia is a treeshrew genus in the family Tupaiidae that was first described by Thomas Stamford Raffles in 1821. The name of this genus derives from the Malay word tupai meaning squirrel or small animal resembling a squirrel.
Tupaiidae is one of two families of treeshrews, the other family being Ptilocercidae. The family contains three living genera and 19 living species. The family name derives from tupai, the Malay word for treeshrew and also for squirrel which tupaiids superficially resemble. The former genus Urogale was disbanded in 2011 when the Mindanao treeshrew was moved to Tupaia based on a molecular phylogeny.
The Bangka Island treeshrew, also known as the Bangkan treeshrew, is a treeshrew species within the Tupaiidae. It was previously listed as a junior synonym to Tupaia glis, but was raised up to species status in 2013. It is only found on Bangka Island, which is off the coast of Sumatra. While there is no study yet about its habitat, it may be similar to T. glis's which resides in primary dipterocarp forest. It is likely that it is threatened by local deforestation.
The Sumatran treeshrew is a treeshrew species within the Tupaiidae family. It was previously listed as a subspecies of Tupaia glis for one hundred years, but was raised up to species status in 2013. It is found on the islands of Sumatra and Tanahbala in Indonesia. It is the type species for the Tupaia genus.
The Javan treeshrew or large Javan treeshrew is a treeshrew species within the Tupaiidae family. It was originally described as a subspecies of Tupaia ferruginea and later listed as a junior synonym of Tupaia glis, but was raised up to species status in 2013. It is found on the island of Java in Indonesia.
