#PLATYPUS EVOLUTION ENDING SKIN#

The skin of the bill contains tens of thousands of specialised sensory receptors that provide a platypus with the information it needs to navigate underwater and capture its prey. The billвЂ™s upper surface is uniformly dark grey its lower surface can either be uniformly grey or quite mottled. The platypusвЂ™s bill is covered by smooth skin with a soft, suede-like texture and (unlike a duckвЂ™s bill) is quite pliable and fleshy around the edges. The extra skin folds under the foot when an animal leaves the water, making it easier to walk or to dig using the sturdy front claws. The front foot ends in a broad expanse of skin that unfurls in the water to form a large and efficient paddle (below). The platypusвЂ™s hind foot is equipped with sharp, curved claws that are used like a comb to groom the fur (as shown at left). The light-coloured patches make it look as if the eyes remain open, reducing the risk of attack by a predator (as shown above).

The fur is dark brown above (except for a small light-coloured patch of fur next to each eye) and creamy white below (sometimes tinged rusty red or brassy yellow). The eyes and ears are both located in a muscular groove that normally pinches shut when a platypus dives. The platypus has a streamlined body and a superficially duck-like bill. A long-term study near Melbourne found that 40% of adults were last captured when 3-5 years old, 36% when 6-8 years old and 24% when 9 or more years old. Life span: Up to 21 years in the wild (males and females). Length of lactational period: 16-20 weeks (in captivity) Length of egg incubation period: 10-11 days Number of babies in a litter: 1-3 (most typically 2) Animals living in the colder/southern parts of the platypusвЂ™s range are generally larger than those found in the warmer/northern parts of its range.ДЄge when first mature: 2 years (males and females) Maximum recorded length = 0.6 metres.ДЄdult weight: Typical weight = 1.0-2.4 kilograms (males), 0.6-1.4 kilograms (females).

'Already the Holocene? My how the time does fly! Seems like t'was but yesterday, when the Moon was nearby.' Now here we are, upon the Moon. And chipped some stone and built some fires to warm the cave abode. The trees were great, but it was late, so onto two we strode. The 'saurs became a little flock of ornithology. 'Now that's a party!' we all sang, and went to mammals be. It turned the Moon a pretty blue, the Sun a shade of green. Then from a distant shore, We saw a comet hit the ground, the best I've ever seen. We'll use the oxygen we make! Come on, it will be fun!' As huge salt mountains melted down to spice the saltless seas, the dosado tectonic dance of plate activities, Trilobites now filled the sea, and oxygen the air, 'What say we all crawl up on land? And have a picnic there!' 'We'll bring amphibians and trees, and Oh, it will be fun! And bring some extra ozone to protect us from the Sun.' So off we went, and partied on, from cynodont to 'saur. Laurence Doyle of SETTI: When the Earth was young, and the Moon nearby, in a cometary sea, prokaryotic thoughts arose, what fun it is to be! 'Lets rust the world!' we all agreed, 'until the iron's done. Story Research: Duck-billed platypus: Primitive or not?ДЎ1/23/07 - The 'implausible' platypus continues to surpriseДЄ Cosmic Evolution By Dr. Story Reteller: April Holladay, Wonderquest, USA today Storytellers: Ondine Evans and Anne Musser of The Australian Museum That's the origin of the word 'monotreme': Mono вЂ“ Greek for 'one,' trema вЂ“ Greek for 'hole.' A simple, successful design. She has a single orifice for all systems: urinary, excretory, and reproductive. She waddles like a reptile with legs to the side rather underneath her body. Indeed she harkens back to an even earlier design - that of the mammal-like reptiles that predated the dinosaurs by 80 million years and lived in the late Carboniferous period, about 300 million years ago. The duckbill platypus is a current member of the ancient monotreme group. This creature's basic design, however, has endured for about 110 million years - one of the longest-lived successful body plans, say Ondine Evans and Anne Musser of The Australian Museum The champs with this good survival strategy are the egg-laying monotremes, a group that evolved about 110 million years ago in the mid Cretaceous period. The duck-billed platypus takes true honors although the species has only been around about 100,000 years.
