What is the name of a mouse that swims in water? - briefly
The water mouse (Xeromys myoides) is a semiaquatic rodent that lives and swims in freshwater habitats. It is the only recognized species commonly referred to as a mouse adapted for an aquatic lifestyle.
What is the name of a mouse that swims in water? - in detail
The creature commonly referred to as a water‑dwelling mouse is the water mouse (scientific name Xeromys myoides). It belongs to the family Muridae and is the sole species of the genus Xeromys.
Native to coastal mangroves and freshwater wetlands of eastern Australia and southern New Guinea, the animal exhibits several adaptations for an amphibious lifestyle. Its fur is dense and water‑repellent, while the tail is flattened, providing propulsion during swimming. Webbing between the hind toes enhances maneuverability in shallow water.
Diet consists mainly of aquatic insects, crustaceans, and small fish, supplemented by seeds and plant material collected along the water’s edge. Foraging occurs both underwater and on the surface, with the mouse capable of holding its breath for up to 30 seconds while pursuing prey.
Reproductive behavior includes the construction of burrows in riverbanks or under mangrove roots. Litters typically contain two to three young, which are weaned after about three weeks and become proficient swimmers within a month.
Conservation status is listed as Near Threatened due to habitat loss from coastal development and mangrove clearance. Protection measures focus on preserving wetland corridors and limiting human disturbance in nesting areas.
Key characteristics:
- Taxonomy: Xeromys myoides (Muridae)
- Habitat: Mangrove swamps, freshwater streams, tidal zones
- Morphology: Water‑repellent fur, flattened tail, webbed hind feet
- Diet: Aquatic invertebrates, small fish, occasional plant matter
- Reproduction: Burrow nesting, 2–3 offspring per litter
- Conservation: Near Threatened, habitat protection required
These details define the specific name and biological profile of the mouse that inhabits and swims in aquatic environments.
