The Kalimantan pointed squirrel ( Tupaia salatena ) occurs south of the Kayan and Rajang rivers on Kalimantan .

features

The Kalimantan pointed squirrel reaches a head-trunk length of 17.5 to 21 cm, has a 17.5 to 20.5 cm long tail and 5 to 5.3 cm long rear feet. The bushy hairs of the tail are about 2 cm long. The weight of the animals has not yet been determined. The color of the fur is similar to the Kalimantan pointed squirrel ( Tupaia glis ) from the Malay Peninsula , but it is a little reddish in color and its hair is longer. The hairs of the tail are longer at the base and get shorter and shorter towards the tip. Like many other Tupaia species, it also shows light, short stripes on the shoulders, which in the Kalimantan shrews are a little reddish in color. The chest is tan , the belly is gray, and there is a dark gray saddle in between.

Way of life

So far, nothing is known about the behavior, lifestyle, diet, activity pattern and reproduction of the Kalimantan shrew. It probably lives primarily in lowland rainforests, is diurnal, and other shrews will feed primarily on insects and fruits.

Systematics

The Kalimantan pointed squirrel was scientifically described for the first time in 1913 by the American zoologist Marcus Ward Lyon as a subspecies of the common pointed squirrel ( Tupaia glis ). Exact morphometric studies of the proportions of the hands finally led to the Kalimantan shrew being recognized as an independent species in 2013.

Danger

No precise information can be given about the population and possible endangerment of the Kalimantan pointed squirrel, as too little data is available. Its range is severely affected by deforestation and the population of the animals is possibly endangered.
