Although mamals are the smallest group of wetland-dependent vertebrates, mammals contain what is probably the most iconic of species—the platypus. Breeding and resting by day in riverbank burrows, the platypus relies on freshwater streams and lakes for its food (aquatic invertebrates), which it collects at twilight and during the night. Swamp rats, water-rats and water mice have similar temporal patterns of habitat use, but unlike the platypus they forage in the vegetation in various fresh and estuarine wetlands.
