The Sunda Koboldmaki ( Cephalopachus bancanus , Syn . : Tarsius bancanus ) is a species of primate from the group of Koboldmakis . He lives on Sumatra , Borneo and offshore islands.
features
Sunda lemurs reach a head body length of around 13 centimeters, the tail is 18 to 21 centimeters long, they are among the larger representatives of the Koboldmakis. Their weight is 100 to 140 grams. Their short, dense fur is yellow-brown in the animals on Sumatra and red-brown in the animals on Borneo. As with all Koboldmakis, the hind legs and the tarsus are elongated. The fingers and toes are also elongated and end in rounded finger pads. As with all Koboldmakis, the head is characterized by the large eyes, the large ears are almost hairless and the teeth are pointed.
distribution and habitat
Sunda goblin lemurs inhabit southeast Sumatra , the island of Borneo, and some smaller, offshore islands such as Bangka (from which their scientific name is derived), Belitung, and the Natuna Islands . The habitat of this species is primarily forests, especially tropical rainforests . But they also live in bamboo thickets and sometimes even in plantations and gardens. Mostly they can be found below 100 meters above sea level.
Way of life
Sunda goblin lemurs are nocturnal tree dwellers. During the day they sleep in dense vegetation or in tree hollows, at night they go in search of food. They move vertically climbing and jumping, with jumps they can cover distances of over 2 meters. Mostly they stay in the low tree regions and rarely come over 2 meters high.
They are territorial animals that mark their territories with urine or glandular secretions. The territories cover around 1 to 3 hectares, the males are larger than those of the females. The territories of the males do not overlap, nor do those of the females. On the other hand, male and female territories partially overlap, but are never congruent. In contrast to other tarsiers, Sunda tarsiers go foraging individually and also sleep alone.
They are very vocal animals. Their screams are mainly heard in the evening and in the morning before going to sleep, they are probably used to mark their territory.
food
Sunda tarsier, like all tarsier, are pure carnivores. The main food is insects, especially jumping freaks and beetles . They also eat small vertebrates such as bats , snakes and birds .
Reproduction
After a gestation period of around six months, the female usually gives birth to a single young. This is very large (around 25 grams) and well developed at birth. It is weaned after around 80 days and sexually mature at one year. In captivity, they can live to be over 16 years old.
Danger
The main threat to the Sunda goblin lemurs is the destruction of their habitat, especially through the establishment of palm oil plantations. They are also hunted and made into pets . The IUCN lists the species as endangered ( vulnerable ).
The species is no longer kept in Europe, the former owner is Rotterdam.
Systematics
Several subspecies are distinguished, the taxonomic status of which is not always clear. The nominate form Cephalopachus bancanus bancanus lives on Sumatra and Bangka (marked in brown on the map), the subspecies C. b. borneanus on Borneo (red) and C. b. saltator (purple) on Belitung. The population on the Natuna Islands is sometimes considered a subspecies C. b. natunensis (green), sometimes it is assigned to the Bornean subspecies.
