The platypus is venomous (the poison comes out of a spur on its ankle) and can locate its dinner using electricity. Monotremes are very odd mammals, if indeed they are mammals at all. Probably the most efficient telegram ever written was on the subject of the humble flatfoot. Secondly, I have already written of how telegrammists paid by the word, and how this changed their prose style. The word is Greek in origin and the plural would therefore be platypodes, or flatfoots. The plural would not and could not be platypi. But platypus is one of those lovely cases where latinising leaves the pedant with linguistic egg upon his face. I have deplored and condemned this habit already. But the Inky Fool is interested only in words.įirst, some irritating people insist upon latinising their plurals. When a specimen was first sent back to Europe from the eldritch antipodes it was widely thought to be a fake that had been stitched together from the parts of other animals. They say this because people can make the water unsafe for the platypus.The platypus is a strange creature. Ecologists say that it is secure but faces future threat (safe now but not in the future) or common but vulnerable (there are a lot now but they are not safe). The platypus will probably not die out completely in the near future. Taronga Zoo in Sydney bred twins in 2003, and had another birth in 2006. Healesville raised another in 1998 and again in 2000. He nearly did it again in 1972 at the David Fleay Wildlife Park at Burleigh Heads, Queensland, but it died at 50 days. David Fleay at the Healesville Sanctuary in Victoria had the first successful zoo raised platypus in 1946. Even today, humans have raised only few platypus. The story told how hard it was to raise platypus babies in zoos. Many people all over the world had never heard of the platypus. National Geographic magazine had a story on the platypus in 1939. They thought an Asian had made it from pieces of different animals. At first, the scientists thought the skin was a joke, because they thought no animal could look so strange. They sent the skin of a dead platypus, so biologists could study it. The first platypus specimen arrived in England in 1799. At Eungella National Park in Queensland, there are spots on the river with viewing areas where wild platypus can usually be seen each evening. They dislike areas with people, spend most of their time underground or under water, and sleep during the day. Platypus are difficult to see in the wild. It does live in some less healthy coastal rivers, for example the Maribyrnong River in Victoria. It is strange that the platypus does not live in some healthy rivers. The water there is no good because people used it to grow plants, and cleared the trees from the land. There are very few if any platypuses left in most the Murray-Darling Basin. There are platypus on Kangaroo Island, but these were brought there in an attempt to save animals people thought might become extinct. In the past, platypus lived in South Australia but they no longer do so. It has been seen in alpine lakes in Tasmania in the south, and north in Queensland as far as the Cape York Peninsula in tropical rain forest rivers. The map above shows this with dark purple. The platypus lives in small streams and rivers over a large area of eastern Australia. The monotremes are a mixture of primitive and advanced traits, a situation known as mosaic evolution. The monotremes share them with all other mammals. The long period as dependent young, the provision of milk, and the way the young learn through play, are all advanced features. After four months they no longer need their mother's milk. At six weeks the babies have fur and are able to leave the burrow for short trips. The young platypus drinks the milk from the mother's skin while she lies on her back. The platypus does not have nipples, but milk comes through small openings in the skin. The mother makes milk for the new babies. When the babies come out of the eggs after about ten days, they hold on to the mother. At the end of the tunnel, she builds a nest out of reeds for her eggs. She blocks the tunnel with earth at several places. When a female platypus is pregnant, the female makes much larger holes, up to 20 m (66 ft) long. It makes these holes in the river bank a little above the water. These holes are between 3 m (10 ft) and 8 m (26 ft) long. When on land, the platypus lives in burrows on the river banks.
