The platypus spends most of its time either sleeping or foraging for food. Most social behavior involves interactions between potential mates during the breeding season or between a mother platypus and her young.
The platypus is normally solitary when not mating or raising its young. A platypus spends about 12 hours a day hunting for food, as it eats about 20 percent of its own body weight daily. It catches fish, aquatic crustaceans, worms and mollusks. The platypus uses its beak to root out prey animals from riverbeds or swims to catch its prey. It stores its captured prey in its cheek pouches until it reaches the surface, where it then eats. When not hunting, a platypus sleeps in a burrow dug into a riverbank.
