The Sangihe Islands – Indonesian: Kepulauan Sangihe – are a group of islands that constitute two regencies within the province of North Sulawesi, in northern Indonesia, the Sangihe Islands Regency and the Sitaro Islands Regency. They are located northeast of Sulawesi between the Celebes Sea and the Molucca Sea, roughly halfway between Sulawesi and Mindanao, in the Philippines; the Sangihes form the eastern limit of the Celebes Sea. The islands combine to total 813 square kilometers (314 sq mi), with many of the islands being actively volcanic with fertile soil and mountains.
The red-bellied squirrel or Sulawesi giant squirrel is a species of squirrel. Until recently, it was described as a species in the genus Callosciurus, but since the 1990s it is generally placed in its own genus Rubrisciurus. It is endemic on the Indonesian island of Sulawesi, where it is widespread. It has also been found on Sangir Island to the north of Sulawesi. With a length of 25 cm, it is rather large for a squirrel. It lives in the tree tops of the rainforests of the island.
The black flying squirrel or large black flying squirrel is a species of rodent in the family Sciuridae. It is found in Brunei, Indonesia, and Malaysia; its habitat is primary and secondary forests and gardens where it uses tree hollows. It feeds on fruits, nuts and other vegetable matter. It is likely not threatened and is adaptable to habitat loss. Black flying squirrels tend to have smaller populations than other squirrels because female black flying squirrels breed infrequently and have a small litter size of just one young.
The northern palm squirrel, also called the five-striped palm squirrel, is a species of rodent in the family Sciuridae. Some authorities recognize two subspecies, F. p. pennantii and F. p. argentescens. It is a semi-arboreal species found in tropical and subtropical dry deciduous forests and many other rural and urban habitats. It is a common species with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".

The whitish dwarf squirrel is a species of rodent in the family Sciuridae. It is endemic to Indonesia, where it is found on Sulawesi, Buton Island, Muna Island, Kabeana Island, and adjacent islands to the southeast of Sulawesi.
The Celebes dwarf squirrel is a species of rodent in the family Sciuridae. It is endemic to northeast and central Sulawesi, Indonesia, and is also found on nearby islands including Sangir Island.
Weber's dwarf squirrel is a species of rodent in the family Sciuridae. It is endemic to northern and western Sulawesi, Indonesia. Its natural habitat is subtropical or tropical dry forests.
The Perote ground squirrel is a species of rodent in the family Sciuridae. It is endemic to Mexico and is currently at risk of extinction. Perote ground squirrels live within the same area as rock squirrels but they use different microhabitats. In one case it also shares its habitat with the Mexican ground squirrel. Perote ground squirrels have traits similar to those of spotted ground squirrels found in the northern Mexican Plateau; however they are larger, have shorter tails and yellow backs. Its skull is relatively narrow with a large braincase and they have heavy, thick teeth. Perote ground squirrels have two annual cycles, an active phase (March–November) and a hibernation phase (December–February). Some overlap may occur in March and November however.
Brooke's squirrel is a species of rodent in the family Sciuridae. It is found in Indonesia and Malaysia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. It was named for Charles Brooke, the second White Rajah of Sarawak by Oldfield Thomas from a specimen collected by Charles Hose on Mt Dulit.
The horse-tailed squirrel is a species of rodent in the family Sciuridae. It is found throughout the islands of Borneo and Sumatra, as well as the southern half of the Malay Peninsula, which includes the entire nations of Brunei and Malaysia, as well as some areas of Indonesia and Thailand. There was a mention of this squirrel being found in Vietnam in 1831, but subsequent descriptions of this squirrel's range have not included that nation.
Jentink's squirrel is a species of rodent in the family Sciuridae. It is named in honor of the Dutch zoologist Fredericus Anna Jentink. It is found in Indonesia and Malaysia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
Low's squirrel is a species of rodent in the family Sciuridae. It is found in Borneo and nearby islets. Its former subspecies S. l. robinsoni from Sumatra and the Malay Peninsula and S. l. natunensis from the Natuna islands have recently been given species status.
The Samar squirrel is a species of rodent in the family Sciuridae. It was historically known as lalagsing. It is endemic to the Philippines, where it has been recorded from Samar and Leyte Islands. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss, due to expanding human activities, hunting, and the lack of basic knowledge about the species. They thrive in primary and secondary lowland and montane forest, including the lower edges of mossy forest. It is also found in some agricultural areas.
Swinhoe's striped squirrel is a small species of rodent in the family Sciuridae. This species is found mostly in China and Southeast Asia. Their diet consists of mostly seeds, fruits, nuts and ginger nectar. Like most squirrels they live in forest areas with mountains, usually in groups. They have litters that average in size of 3.25 offspring.
