No other animal on the planet besides maybe echidnas reproduce and raise young exactly in this manner. The young are weaned for three to four months after hatching from the eggs and become independent a short time later. This may have powerful applications for future human antibiotic use. Interestingly, the milk contains powerful antibiotics to protect the young from infection.

Since the female lacks teats of any kind, the milk leaves the body through skin pores in the abdomen. Milk production is an interesting process.

The developing embryos rely on the yolk for sustenance.ДЄfter the eggs are finally hatched, however, the mother will begin producing milk for her young. After a pair of platypuses mate, the female produces a few small, leathery eggs, which spend about 28 days inside of her body and then another 10 days being incubated externally. The first part of the reproductive process is similar to a reptile. The name monotreme itself means вЂњsingle opening.вЂќ This refers to the single duct through which it urinates, defecates, and reproduces. Whereas all other groups of mammals still living on the planet give birth to live young, the monotremes are distinguished by their ability to produce eggs instead. But the reproductive behavior of the platypus is so much stranger than that. The name вЂњmammalвЂќ is a testament to the importance of these glands in the classification and identification of the entire mammalian class. Perhaps the most important mammalian feature is the milk-producing mammary glands that the female platypuses possess to feed the young. JohnCarnemolla The platypus has mammary glands Platypuses are mammals called Monotremes.

A Platypus swimming in a Tasmanian creek. Some of the similarities are expected, but a few of them might be surprising. This article will explore the six major characteristics that the platypus shares in common with most other mammals. Even its bill only shows a superficial resemblance to the duck itвЂ™s actually filled with electric sensors that enable it to navigate underwater even when it lacks sight.Дespite these eccentric characteristics, born from its different evolutionary path, the platypus bears all the hallmarks of mammalian ancestry. The highly potent venom, which the male delivers through sharp spurs located on the ankles, contains chemicals largely unique to the platypus.

It has 10 different sex-determining chromosomes, as opposed to only two in humans and other mammals. Its reproduction is a unique fusion of mammalian and reptilian characteristics. The marsupials had several advantages over the monotremes and probably outcompeted them for resources.ДЄs the descendent of these surviving monotremes, the platypus is really like no other animal on the planet. The main turning point which caused their decline was probably the arrival of marsupials some 71 million to 54 million years ago from continental Asia. The fossil evidence suggests that the monotremes were once the dominant form of mammalian life in Australia and may have spread as far as South America. They form an entirely separate evolutionary branch, distinct from placental mammals and pouched marsupials, with which they last shared a common ancestor some 166 million years ago. We now know that this small semi-aquatic mammal, which can be found in the freshwater rivers and estuaries of eastern Australia and Tasmania, belongs to an order of animals called the monotremes.Д«esides the platypus itself, there are only four other species of monotremes left on the planet, all of which are echidnas (also known as spiny anteaters). The animal seemed to blur the lines between different classifications, back when the science of taxonomy was still growing. They even checked the original platypus specimen for stitching. When it was first described by zoologist George Shaw around 1800, many of his peers thought it was a hoax. At first glance, the platypus looks like a strange hybrid animal straight out of Greek mythology.
