The oryzorictinae (Oryzorictinae) are a subfamily of the mammalian family of tenrecs (Tenrecidae). With around 20 species in three genera, they represent the most species-rich group of Tenreks.
Travel treks are small animals that live exclusively in Madagascar . They reach a head body length of 4 to 17 centimeters, in contrast to most other tenreks, they usually have a long tail that is approximately the length of the body. The fur of these animals is gray-brown and lighter on the underside. They are carnivores that inhabit different habitats.
A distinction is made between three types:
- The rice burrowers ( Oryzorictes ) include two species that are reminiscent of moles with their burrowing way of life.
- The Kleintenreks ( Microgale ) are the most species-rich group with about 22 species. These small animals often have a shrew-like appearance.
- Nesogale comprises two species, originally they were placed among the Kleintenreks, but according to genetic studies they belong to a genus of their own.
The water tenrek ( Microgale mergulus ) was originally listed in its own genus ( Limnogale ), but according to genetic studies it is deeply embedded in the genus Microgale . In contrast to the land-dwelling small tenreks, the water tenrek is adapted to an aquatic way of life and inhabits bodies of water.
In some systematics, the Erdtenrek is also placed in this subfamily, but nowadays rather in its own subfamily, Geogalinae.
