Answer:
Platypuses eat small crustaceans such as yabbies that live on the bottom of creeks and rivers. They also eat other kinds of small aquatic invertebrates, such as worms, freshwater crayfish, insect larvae, and freshwater shrimps.
Platypuses catch their food in the water. They may make hundreds of dives in a single day. The bill of a platypus has sensitive electroreceptors which pick up tiny nerve and electrical impulses generated by crustaceans and other animals that inhabit the bottom of the creek or river. The platypus then uses its bill to shovel away the dirt, and find the food.
