Use the paragraph to answer the question.
The platypus is an Australian mammal that is not easily classified. It is one of only two
mammals (the other being the echidna) that bears young by laying eggs. In some
respects, the platypus resembles a duck; both have webbed feet and bills. The platypus
has a tail like a beaver’s and a furry body similar to an otter’s. Its unusual hybrid of body
parts makes it well-suited for its largely aquatic life. The platypus uses its webbed feet to
paddle through water, and its tail serves as a kind of rudder for steering. While
underwater, the platypus uses its bill to scoop up bits of food, such as insects and
shellfish, from the water’s bottom. The platypus also scoops up bits of gravel, which grind
up the food, as the platypus is toothless. The platypus stores the food and gravel in its
cheeks until it reaches the water’s surface. Once the platypus surfaces, it consumes its
meal.
