Platypuses do not live in the desert. They are semi-aquatic mammals found only in eastern Australia, specifically in areas with rivers, streams, and wetlands.
* They need water: For hunting, cooling down, and raising young. Deserts lack consistent water sources.
* They need specific food sources: Aquatic insects, worms, and crustaceans.
* They need specific habitat: They build burrows in riverbanks. Deserts lack suitable soil.
Platypuses are perfectly adapted to their wet, watery environment and would not survive in desert conditions.
