![]() ![]() All that said, they do have one particular adaptation to ease their terrestrial travel: The webbing between their front claws-a boon when paddling through streams- retracts when the platypus ambles up the riverbank to expose sharp claws. Out on land, the platypus's short limbs mean it has to exert 30 percent more energy than a similarly sized land-based mammal just to move around. Much like an otter, they prune their thick coat to add air bubbles that act as insulation in the cool rivers where they hunt. Platypuses have retractable webbing.Īlthough they can only stay submerged in water for a few minutes-they are mammals, after all-platypuses are much better suited to scooting around in water than they are on land. Although the spur itself is always there, the venom gland to which it is connected is seasonally-activated and only produces venom during mating season, indicating that its use is for fending off competing males. Instead, males have a hollow spur on each hind leg from which venom is dispensed-but only sometimes. But unlike snakes, a platypus’s venom isn’t in his teeth. Platypuses are one of just a few venomous mammals, which is one of their more reptilian characteristics. The babies drink it up by sucking it out the folds of their mother's skin, or her fur. Instead, their milk is released out of mammary gland ducts on their abdomen. Female platypuses, however, don’t have nipples. Platypuses nurse without nipples.Īlthough platypuses are born out of leathery eggs, the babies nurse from their mother. 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. 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-and platypuses are no different. It’s so sensitive that the platypus can hunt with its eyes, ears, and nose all closed, relying entirely on the bill’s electrolocation. Platypus bills give them a “sixth sense.”Ī platypus’s bill has thousands of cells that give it a sort of sixth sense, allowing them to detect the electric fields generated by all living things. Platypuses ( platypodes and platypi are technically also correct, but much rarer in use) aren't the only animals to forgo an acid-producing part of the gut spiny echidnas, and nearly a quarter of living fishes all have a gullet that connects directly to their intestines. Here are a few things you might not have known about this quirky creature. Like other mammals, monotremes have fur, nurse their young with milk, and are warm-blooded.The platypus is arguably one of the most distinct animals on the planet. In other mammals, the cloaca is divided into an anus and genitourinary passages. Monotremes, like all reptiles, also have a cloaca, a single opening through which feces, urine, and sperm or eggs pass. ![]() In monotremes, the eggs are fertilized internally, but are incubated and hatched outside the body. In other mammals, the young are conceived within the female's body and are born alive. For example, monotremes are the only egg-laying mammals. All three species in the order Monotremata are considered primitive, combining mammalian features with those of lower orders of vertebrates such as reptiles. There is only one species of platypus, Ornithorhynchus anatinus, which is comprised of four subspecies. ![]() The platypus is classified in the order Monotremata (meaning single hole), consisting of two families and three genera the families are Tachyglossidae (spiny anteater family) and Ornithorhynchidae (platypus family). ![]()
