Dasymys is a genus of semiaquatic rodents in the subfamily Murinae, the Old World rats and mice. The genus is endemic to Africa.[1]
These rats are wetland habitat specialists, occurring in marshy areas with wet ground and thick vegetation, such as swamps and vleis. They swim well. They are nocturnal and solitary.[2] Species are more common in the northern regions of Sub-Saharan Africa, likely because their wetland habitat is more degraded in southern regions.[3]
The genus is not well studied and its taxonomy is not clear. The number of species and their relationships have only been tentatively determined.[2]
Species include:
Dasymys alleni – Glover Allen's dasymys
Dasymys cabrali – Crawford-Cabral's dasymys
Dasymys foxi – Fox's shaggy rat
Dasymys incomtus – African marsh rat
Dasymys montanus – Montane shaggy rat
Dasymys nudipes – Angolan marsh rat
Dasymys robertsii - Robert's shaggy rat
Dasymys rufulus – West African shaggy rat
Dasymys rwandae – Rwandan dasymys
Dasymys shortridgei
Dasymys sua – Tanzanian dasymys
