Scientific Name: Chimarrogale phaeura Thomas, 1898
Common Name(s):
English Bornean Water Shrew, Borneo Water Shrew, Sunda Water Shrew
Taxonomic Notes: C. phaeura was considered a subspecies of himalayica by Medway (1977), but Corbet (1978) and Jones and Mumford (1971) distinguished styani and phaeura as separate species. Additionally, sumatrana was considered part of phaeura by Ellerman and Morrison-Scott (1966), but Gureev (1979) listed them separately.

Population:The abundance and population size of this species are not known.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:The species is considered to be semi-aquatic, and its diet is primarily composed of invertebrates. The species prefers moist habitats in montane forest, and can be found by streams in tropical forests in addition to marshland habitats. It is not known whether or not it can adapt to disturbed habitats. The species can be mistaken for C. himalayica due to its similarities in appearance and size.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: This species is not utilized.

Threats [top]

Major Threat(s): This species has a small range, and it is confined to a restricted habitat that is under pressure from human encroachment, especially for logging. It is not known whether or not it can adapt to anthropogenic habitats, but the extensive habitat loss within its range is likely to be having an impact, and the species is probably ecologically sensitive.

Conservation Actions [top]

Conservation Actions: This species occurs in Kinabalu National Park. Further studies are needed into the distribution, abundance and conservation needs of this species.
