It is one of only two mammals the echidna is the other that lay eggs. Females seal themselves inside one of the burrow's chambers to lay their eggs. A mother typically produces one or two eggs and keeps them warm by holding them between her body and her tail.
The eggs hatch in about ten days, but platypus infants are the size of lima beans and totally helpless. Females nurse their young for three to four months until the babies can swim on their own.

Size relative to a 6-ft man:.
Near threatened. They are excellent swimmers, but move cumbersomely and comically on land. They use their sensitive bills to detect the tiny electrical signals from crabs and shrimps at the bottom of rivers and lakes. Their claws are sharp and strong, while males have a poisonous spur on their rear ankles which can be used in self defence or in fighting off rival males. Females lay two or three eggs the size of grapes at the end of a long burrow lined with grass. The young hatch after 10 to 12 days and then feed on their mother's milk for five months before leaving home.
The sequencing of its genetic code gives scientists the chance to discover new genes, and work out how humans and other mammals evolved. It could also lead to new drugs. Dr Kathy Belov, from the Faculty of Veterinary Science at the University of Sydney co-author on the Nature paper, said: "We identified 20 new antimicrobial peptides in the platypus genome and are now testing them to see which bugs they kill. The study found that platypus venom is a cocktail of chemicals - including some found in snake venom, even though the two creatures evolved independently.
Research into the creatures' venom could also lead to new painkillers, the scientists say. Past studies suggested that they are an early offshoot of the mammal family tree that broke away million years ago - during the time of the dinosaurs. The new study was carried out by scientists. The team discovered that its peculiar characteristics were mirrored by a patchwork of genes resembling those from mammals, birds and reptiles.
Dr Chris Ponting, of the MRC unit at Oxford, said: "The platypus genome is extremely important because it is the missing link in our understanding of how we and other mammals first evolved. It also provides an essential background to future advances in understanding mammalian biology and evolution. No comments have so far been submitted.

The platypus's tail is used as a rudder, for steering when it is swimming, but it also stores fat. A thicker tail is the sign of a healthier platypus. They don't. Platypuses swim with a platypus's tail. A beaver is a rodent which bears live young; a platypus is a monotreme egg-laying mammal A beaver has large front teeth; platypuses have a bill with no teeth, but grinding platesPlatypuses live in Australia and beavers live in North America and Canada.
A platypus has a beaver tail and 4 webbed feet. Their tails serve quite different purposes. The female tends to live on the fat stored in her tail while she incubates her eggs. No, a beaver isn't related to a platypus.
Even though they're both mammals, a beaver gives birth to live young while a platypus lays eggs. No, there is no difference whatsoever.
