The Nicobar white-toothed shrew ( Crocidura nicobarica ) is a rare, little-researched shrew from the genus of the white-toothed shrew ( Crocidura ). It is endemic to Greater Nicobar in the Nicobar Islands .
features
The sizes and characteristics are only known from the type specimen , a female, which was collected by William Louis Abbott in March 1901 . The head-torso length is 120 mm. The slightly damaged tail is 90 mm long. The ear length is 11 mm. The slightly damaged hind feet are 24 mm long. No specific data are available on weight. The back fur of the Nicobar white-toothed shrew is dark brown mixed with gray hair. It's dense, frizzy, and velvety with hair flattened, widened, and thickened at the edges. The hair in the middle of the back is about 4 mm long. The underside is brown with an elongated gray spot in the middle. The light brown tail is three quarters of the length of the head and torso. It is sparsely covered with bristle hair. There are apparently two inguinal teats on each side. However, since the specimen is damaged, this information is considered unsafe.
distribution
The terra typica of the holotype is located in the south of Great Nicobar. The known total area of the distribution area is 96 km².
Habitat and way of life
The Nicobar white-toothed shrew is a nocturnal species. It occasionally digs passages and lives in the leaf litter of tropical, moist deciduous forests at altitudes of 100 m. Nothing is known about their feeding and reproductive behavior.
Threat and protection
The IUCN classifies the species as " critically endangered ". The last confirmed sighting took place in 1975 at the mouth of the Galathea in Campbell Bay National Park on the southern tip of Groß Nikobar. In the period that followed, the region was completely destroyed by road construction work, so that no more specimens were found during an expedition in 1984. The main hazard is considered to be habitat loss due to selective logging and general anthropogenic activities.
