Standard English Name
Brazilian common name/s
This animal is one of the least known mammals in South America. It has a length of 40 to 60 cm and brown colouration, with a ventral region a little clearer. The four feet have no hair on the surface and the fingers are connected by membranes, suggesting a semi-aquatic habit.
Ecology and Habitat
The distribution of this species is uncertain, but there are records from some isolated locations throughout most of the Amazon basin, from the east of Ecuador to north-east Peru.
The diet probably consists of small vertebrates.
Threats and Conservation
As it is a poorly studied species there is as yet no clear idea of the population status. The few available records suggest that it is naturally rare and it is assumed that the destruction of their habitat could compromise even more strongly the survival of the species. The species is classified by IBAMA as threatened with extinction.
