The Grant galago or Grant dwarf galago ( Paragalago granti , Syn . : Galago granti , Galago nyasae , Galagoides granti ) is a species of primate from the Galagos family (Galagonidae). It used to be combined with the Zanzibar Galago to form one species, but differs from it, among other things, in the sounds and in the construction of the reproductive tract .
features
Grant Galagos are, like all Galagos, relatively small primates, they can reach a weight of 100 to 200 grams. On the basis of 50 examined individuals, an average head-trunk length of 15.4 and a tail length of 22.1 centimeters could be determined, the weight averaging 147 grams. The average length for the hind foot was 5.9 centimeters and the ears 3.8 centimeters. The fur of the animals is colored red-brown on the upper side, the underside appears yellowish or cream-colored. The tail is slightly bushy and longer than the body, the hind legs are strong. The muzzle is elongated, the eyes are large, the ears are also large, hairless and very mobile. In the side view, the nose profile is indented. The average skull length is 4.2 centimeters.
Distribution and way of life
Grant Galagos live in eastern and southern Africa , their range includes the coastal regions of southern Tanzania and Mozambique as well as the neighboring regions of Malawi and Zimbabwe . According to field studies from 2011 to 2014, the species is also found in northeastern South Africa . Their habitat is the coastal forests, but also mountain forests inland up to 1800 meters above sea level.
Little is known about the way these animals live. Like all Galagos, they are nocturnal and mainly live in the trees. The sleeping places are mostly in wooded landscapes, but the animals also penetrate into more open areas to forage. As a result, the Grant Galago predominantly prefers mosaic landscapes of thickets, dense forests interspersed with lianas , and dry forests. The diet consists of fruits, insects and tree sap. The calls of the animals are characteristic. These include screeching or high-pitched sounds as well as a male advertising profession. The latter consists of a building sequence of tones to which new units are constantly being added. This distinguishes the Grant-Galago, among other things, from the Moholi-Galago , whose advertising profession sounds rather monotonous.
Danger
Grant Galagos are widespread and common, the IUCN lists the species as "not endangered" ( least concern ).
