The Andaman white -toothed shrew or Andaman shrew ( Crocidura andamanensis ) is a rare, little-researched species of shrew from the genus of the white-toothed shrew ( Crocidura ). It is endemic to South Andaman Island in the Andaman Islands and was thought to be lost between 1901 and 1997.
features
The head-body length of two measured specimens is 75.9 and 114 mm, the tail length 69.3 and 86 mm and the hind foot length 24.3 and 26 mm. No specific data are available on weight. The back fur of the Andaman white-toothed shrew is gray with a brown wash. Some hairs are a little flattened but not widened. The fur hairs in the middle of the back are 6.5 to 8 mm long. The peritoneum is gray with a less obvious brown wash. The dark brown tail has bristle hairs on 55 to 75 percent of its length.
distribution
The terra typica of the holotype is located on MacPherson Strait on South Andaman Island. Another specimen was collected at Mount Harriet . The known total area of the distribution area is 51 km².
Habitat and way of life
The Andaman white-toothed shrew is a nocturnal species. It lives in the leaf litter and crevices of tropical, moist deciduous forests and evergreen forests at altitudes of 100 to 383 m. Nothing is known about their feeding and reproductive behavior. Among the possible seizure free ends include snakes , the Andaman scops owl ( Otus balli ) and the Andaman subspecies of larvae Rollers ( Paguma larvata tyttleri ).
Threat and protection
The Andaman white-toothed shrew was known for a long time only from the holotype collected by William Louis Abbott (1860-1936) in January 1901 , until Indraneil Das was able to catch another specimen in the same forest guest house in Mount Harriet National Park in August 1997, in which he also one Specimen of the Jenkins white-toothed shrew ( Crocidura jenkinsi ). The animal climbed with great agility and ran on a window ledge within a room two meters above the floor. The IUCN classifies the species as " critically endangered ". The main hazard is considered to be habitat loss due to selective logging and general anthropogenic activities. The habitat on MacPherson Strait was believed to have been destroyed in the December 2004 tsunami .
