Duck-Billed platypuses live in burrows along rivers, lagoons, and streams in Australia. The female platypuses usually make two burrows, one for themselves and a male (they mate from July to August) and another for having babies. They prefer areas with steep banks that contain roots, overhanging vegetation, reeds, and logs. They usually live in streams or rivers no more than five meters deep, but sometimes can live in rivers or streams 1,000 meters deep. They're found in temperate, tropical, terrestrial, and freshwater. They can eat shrimp, insect larva, earthworms, meal worms, and crayfish may flies, dragonflies, mussels, trout eggs, frog eggs, tadpoles, small frogs. The platypus looks for its food by diving to the bottom of streams or rivers with their web feet and drags their head along the mud to find the food. When they swim they close their eyes, ears, and nostrils so how would they see? They see in water by sensing electric currents created by their preys muscle movement.
