Platypus
The platypus sleeps during the day and moves mostly at night. It is a very good swimmer and spends much of its time in the water. The toes on its feet are joined. When it swims, it pushes itself along by moving the front two feet. The tail and back feet help it to turn left or right but do not make it faster. The platypus eats other animals. It eats worms, insect larvae, shrimps, and yabbies, which are a kind of freshwater crayfish. It digs these animals out of the bottom of the river with its beak or catches them while swimming. Its nose can sense many things that other noses cannot. The platypus can sense electricity from other animals. It keeps its eyes shut when swimming, using only its other senses, such as hearing, touch, and changes in the electrical field. The platypus can also hunt without using its eyes. These are adaptations to life in rivers where the water is opaque with sediment.
