Sumatran Water Shrew

Chimarrogale sumatrana View in CoL

French: Chimarrogale de Sumatra / German: Sumatra-Wasserspitzmaus / Spanish: Musgano de Sumatra

Other common names: Sumatra \ Water Shrew

Taxonomy. Crossogale sumatrana Thomas, 1921 ,

“ Pager Alam , Padang Highlands ,” Sumatra, Indonesia.

Chimarrogale sumatrana used to be included in a different genus, Crossogale with C. phaeura , but this is not sufficiently supported. Monotypic.

Distribution. Known only from Padang Highlands of S Sumatra. View Figure

Descriptive notes. Head-body 112-115 mm, tail 90-95 mm, hindfoot 20-25 mm. No specific data are available for body weight. Condylo-incisive lengths are 14-1-14-2 mm, and tooth rows are 13-13-4 mm. The Sumatran Water Shrew is known from two specimens. Fur is similar to the other species of Chimarrogale but lighter. Dorsal pelage is sooty gray and gradually becomes paler on venter. Guard hair piles on rump. Tail is uniformly dark brown, and underpart is covered with brown hair. Skull is similar to that of the Bornean Water Shrew ( C. phaeura ) exceptit is larger and heavier. Medial tines of upper incisors are well developed so that apexes are separated, and talons (posterior cusp) of these teeth are well developed. Cusps of teeth are unpigmented. There are three upper unicuspids.

Habitat. Presumably streams in montane forests at elevations of 500-1600 m.

Food and Feeding. Diets of the Sumatran Water Shrew primarily consist of benthic organisms, including insects, aquatic larvae, crustaceans, and small fish.

Breeding. No information.

Activity patterns. The Sumatran Water Shrew has physical adaptations for aquatic life and is semi-aquatic. It is presumably similar to the other species of Chimarrogale , swimming in rivers and streams and moving along their banks to higher ground.

Movements, Home range and Social organization. The Sumatran Water Shrew creates burrows, with the entrance usually located within the stream.

Status and Conservation. Classified as Data Deficient on The IUCN Red List. Additional research is needed to understand ecology and conservation status of the Sumatran Water Shrew.
