The small-eared giant galago or northern giant galago ( Otolemur garnettii ) is a species of primate from the Galagos family (Galagonidae).
features
Small-eared giant galagos reach a head body length of 23 to 33 centimeters, the tail is around 36 centimeters long and the weight is 0.7 to 0.8 kilograms. The fur color varies from red-brown to gray-brown, the underside is lighter. The fur is woolly and dense, the tail is very bushy and longer than the body. As with all Galagos, the eyes are enlarged as an adaptation to the nocturnal lifestyle, the ears are also large, but smaller than those of the large-eared giant Galagos .
distribution and habitat
Giant small-eared galagos are native to eastern Africa , their range extends from the extreme south of Somalia via Kenya to Tanzania and also includes offshore islands such as Zanzibar . The habitat of these animals are forests, although they can be found in various forest types - such as coastal, mountain and gallery forests.
Way of life
These primates are nocturnal, during the day they sleep in leaf nests. At night they go in search of food, mostly in the trees and rarely on the ground. They move on all fours and rarely jump.
They are territorial animals, their territories do not overlap with those of animals of the same sex and the same age. However, there can be overlaps between territories of males and females or between younger and older ones. The districts are around 12 to 18 hectares in size.
The diet consists primarily of fruits, but they also consume insects and tree sap.
After a gestation period of around 130 days, the female usually gives birth to a single young. After four to five weeks, the young will start to eat solid food, and sexual maturity occurs at around 20 months. In human care, the animals can live to be over 18 years old.
Danger
Small-eared giant galagos are widespread and adaptable. There are no known major threats, the IUCN lists the species as "not endangered" ( least concern ). The small-eared giant galago occurs in various protected areas, including the national parks Aberdare Meru , Mount Kenya and Tsavo-West in Kenya as well as Jozani-Chwaka-Bay , Lake-Manyara , Selous and Udzungwa-Mountains in Tanzania and possibly also in the Serengeti .
