In 2008, scientists deciphered the entire DNA of the duck-billed platypus and determined that, in accordance with the animal’s somewhat bizarre appearance, the platypus shared genes with reptiles, birds, and mammals. These egg-laying mammals get their name from the hole that serves as both an anus and a urino-genital opening. Platypuses are one of only five species of extant monotremes-just them and four species of echidna-which split from the rest of the mammals 166 million years ago. ![]() The platypus is a monotreme-which means “single hole” in Greek. Platypuses are no different: In 2013, the discovery of a single tooth helped researchers identify a prehistoric platypus that was more than three feet long-double the size of the modern animal. The ancient versions of a lot of modern animals, including penguins, were oversized monsters compared to the animals we know today. It’s so sensitive that the platypus can hunt with its eyes, ears, and nose all closed, relying entirely on the bill’s electrolocation.

Neither the eyes nor the ears of the platypus are used for finding food.The hind paws of a platypus are used as rudders when swimming, the long claws on the paws are used for grooming and an anchor when digging. The eyes are on top of the head and help them see in the water. Another adaptation platypuses have are eyes and ears. They also use their paws for digging burrows. The webbing on the paws go away when platypuses are on land. They use their front paws to propel through water, and the front paws act like paddles. Another adaption a platypus has is its front paws.
