Mammals that lay eggs instead of giving birth to live young Like other monotremes, the platypus has a sense of electrolocation which it uses to detect prey in water while its eyes, ears and nostrils are closed It is one of the few species of venomous mammals as the male platypus has a spur on each hind foot. that delivers an extremely painful venom. The unusual appearance of this egg laying, duck billed beaver tailed mammal at first baffled European naturalists In seventeen ninety nine, the first scientists to examine the preserved platypus body judged it a fake made of several animals sewn together The unique features of the platypus make it important in the study of evolutionary biology in a recognizable and iconic symbol of Australia. It is culturally significant to several Aboriginal peoples who also used to hunt for food and has appeared on stamps and currency Australian Aoriginal people have referred to the platypus in various ways pending on Australian indigenous languages and dialects Among the names found Bundibborough.

British scientists's initial hune was that the attributes were a hoax. George Shaw, who produced the first description of the animal In the Naturalist miscellane in seventeen ninety nine stated it was impossible not to entertain doubts as to its genuine nature And Robert Knox believed because it arrived in England via the Indian Ocean that it might have been created by Chinese sailors It was thought somebody had sewn a duck's beak onto the body of a beaver like animal Shaw used a pair of scissors to check for stitches The common name pllatypus means flatfot. Deriving from the Greek word platupus pllatus Broad wide flag. and pooce aw initially assigned the species the Lenan name Flatibus and itinus when he described it The genus term was quickly discovered to already be in use. is the name of a beetle genus Plypus It was independently described as Ornus Anchus paradoxis. by Johann Blumenbach in eighteen hundred from a specimen given to him by Sir Joseph Banks and following the rules of priority of nomenclature, It was later officially recognized as Ornesarenus Anatinus Various dictionaries list platypuses or simply platypus as the plural. Alternatively, the term platai is also used for the plural Although this is a form of pseudo Latin going by the words Greek roots, the plura would be pllatipides Early European settlers called it by many names such as water mole Occasionally it is specifically called the duck build platypus There is no official term for Platypus young but the term pllata pub sees unofficial use. as does Bgle The scientific name Mn as Anas and Ainas. literally means Duck like bird snout Deriving the genus name from the Greek root Ornith bird and the word Runkus species's name is derived from Latin Anatinus, duck like Honest. Platypus is the sole living representative or mototypic taxon of its family. Most of the platypus's small streamlined body covered with short, dense brown fur traps a layer of insulating air to keep the animal warm bos in and out of water The fur coat is waterproof. and consists of flattened guard hairs and curvy under fur hairs It is one of the most densely furred mammals Behind only otters It is also biolorescent. and glows cyan and green when under ultraviolet light. This may serve to camouflage it in low lighting from UV sensitive predators It is also unique among mammal in having hair pigmentation melanosomes that are hollow The duck like bill consists of a long snout and lower jaw which is covered in soft skin Nostrils are located near the tip of the snout's dorsal surface Well the eyes and ears are just behind the snout in a groove which closes underwater It has cheek pouches for storing food The platypus's wide flat tail is compared to a beaver's. but is furry rather than scaly It stores fat reserves and can act as a rudder during swimming The legs are short and have a sprawling stance Webbing is more significant on the front feet while walking on land, The feet are folded up in knuckle walking to protect the webbing. The platypus has an intercavicle in the shoulder girdle a trade which they share in common with reptiles. As in many other aquatic and semi aquatic vertebrates Bone show osteoslerosis increasing their density to reduce buoyancy Adult platypuses lack teeth and instead have heavily cratonized food grinding pads Young platpuses have won pre molar twos two molars on each maxi. and three molars on the deendes The first upper and third lower cheek teeth have only one major cusp Well the rest have two They lose their teeth around the time they leave their natural burrow Pepus lacks a functional stomach due to the lack of genes necessary for creating and secreting peps and proteases. However, the platypus's digestive tract has a pouch like section. that assists with nutrient absorption in the intestines Male platyupuses have an average length of fifty centimeters. and weight of se thousandventeen hundred grams While females are smaller with an average length of forty three centimeters, and weight of nine hundred grams Species follows Bergmann's rule with individuals being larger, the farther south they are due to colder climates. There are local variations, however Platpus has an average body temperature of about thirty two degrees Celsius lower than the thirty seven degrees Celsius typical of placento mammals Research suggests this has been a gradual adaptation to harsh environmental conditions ammong the few marginal surviving monitreing species rather than a general characteristic of past monitreamings Monotreames are the only mammals apart from the Gana dolphin Known to have a sense of electroception. Planopus relies on electrlocation when feeding. as the eyes, ears, and nose are closed while underwater digging in the bottom of streams with its bill It electro receptors detect tiny electric currents generated by the muscular contractions of its prey Eperiments have shown that platyposts will even react to an artificial shrimp If a small electric current has passed through it The forty thousand electroceptors are arranged in rows in the skin of the bill F front to back while mechanic receptors for touch are uniformly distributed across the bill The electrosensory area of the cerebral cortex is in the tactile seatosensory area. And some cortical cells receive input from both electroceptors. and mechanaceptors suggesting that Platypus feels electric fields as touches. These receptors in the bill dominate the seomatatopic map of the platypus brain In the same way, human hands dominate the Penfield Homunculus map us can feel the direction of an electric source pererhaps by comparing differences and signal strengths, across the array of electroceptors enhanced by the characteristic side to side motion of the animal's head while hunting It may also be able to determine the distance of moving prey via the timing difference between electrical and mechanical pressure sensations Monitoring molectrolocation for hunting in murky waters may be tied to their tooth loss. The extinct abdurodon was electroceptive But unlike the modern platypus, It forged in open water The eyes of the platypus have basal traits Also found in lung fish and amphibians such as flural cartilage Double cones and droplets Platypus's eyes are small and shut underwater Though several features indicate its ancestors relied on vision As with other aquatic mammals The eye has a flattened cornea and surrounding lens. while the posterior surface of the lens is sharply inclined. A temporal ears side concentration of retinal ganglion cells Important for binocular vision indicates a vestigial role and predation. Though the actual visual acuity is insufficient for such activities. Limited acuity is managed by low cortical magnification. a small lateral geniculate nucleus. and a large optic tctum. suggesting that the visual midbrain plays a more important role than the visual cortex. As in some rodent These features suggest that the platypus has adapted to an aquatic and nocturnal lifestyle developing its electros sensory system at the cost of its visual system This contrasts with the small number of electroceptors in the short beak echidnena which dwells in dry environments. While the long beak echidnena, which lives in weter habitats is intermediate between the other two monotremes. The ears of the platypus are adapted for hearing while out of water as in all true mammals It has three middle ear bones cochlea lack spirals is described as well organized Within the cochlea, there are rows of inner and outer hair cells As in placento mammals The outer haer cells of the platypas are adapted for hearing high frequencies suggesting it is an ancestral mammalian trait However, it also possesses more rows of inner hair cells the olfactory smelling systems of the platypus and the echidnena Independently evolved from an ancestor with less advanced smelling The main olfactory bulb of the platypus lacks the complex layers of the echidnaa Both the piriform corteags and flabs are simpler Motreames differ from placental mammals. in that their miteral cells are distributed throughout the outer plexiformform layer of the olfactory bulb rather than packed as a monolayer While both male and female platypuses are born with back ankle spurs, Only the males retain them into adulthood Similar spurs are found on many archaic mammog groups indicating that this was an ancient general characteristic among mammals Spurs of the male inject venom which is powerful enough to inflict pain in humans startarting from the wounded area The affected limb develops edema swelling via fluid buildup which can lead to an excruciating hyperglesia heightened sensitivity to pain That can last as long as months. The venom is composed largely of defensin like proteins, DLPs produced by the immune system someome of which are unique to the species It is produced in kidney shaped alveolar glands located in each of the thighs of the hind limbs and connected to the spur The venomous spurs of male platypuses serve as weapons in battle with other males for breeding. Platipus is native to the freshwaters of eastern Australia Queensland to Tasmania believed to be extinct on the South Australian mainland was the last sighting recorded at Renmg in nineteen seventy five es were captively bred at Waran Wang Sanctuary in nineteen ninety to ninety one. October twenty twenty, a nesting platypus was filmed in the wild. previously abandoned sanctuary reopened. There's a population on Kangaroo Island introduced in the nineteen twenties. said to stand at one hundred and fifty individuals in the Rocky River region of Flinders Chase National Park The plpus is semi aquatic. and requires permanent freshwater habitat Hs swimming style is unique among mammals pelling itself by alternating strokes in each front foot while the webb, hind feet and tail are used for steering It can maintain its relatively low body temperature when feeding in colder depths of below five degrees Celsius In one study Dives lasted on average thirty five seconds. with surfacing intervals averaging thirteen seconds. Species is mainly nocturnal but is also active at dusk during the summer and daytime during the winter. Platypus may spend half the day in water and then retreat into its burrow which is constructed by digging into the bank These vary between simple resting banks and complex nesting breeding burrows It may have a range of up to seven kilometers. with a male's home range overlapping those of three or four females Platippuses are not very vocal They've been recorded to growl when disturbed and squeak when feeling pain The platypus is a carnivore and forages by probing along the bottom. It feeds on insect larvae Analed worms shrim Grayfish fiveive vows Pes. and fish eggs It stores food in its cheek pouches for later consumption In activity, platypuses have survived up to thirty years Wild specimens have been recaptured at twenty four years old. They are preayed upon by Murray Cod. Eels Carpet snakes Ganas Eagles crocodiles and foxes. Parasites and viruses also affect their mortality Though Platypuses appear to have a high tolerance for them. Externally, platypuses may carry fleas, mites, and ticks the latter being more prominent in young Oedpuses are seasonal breeders with some more southerly populations breeding later in the year than those further north Those in New South Wales made during fall and winter During incubation and weaning The mother initially leaves the burrow only for short periods to forage She leaves behind her a number of thin soil plugs along the length of the burrow Pushing past these on her return squeezes water from her fur and allows the burrow to remain dry The female spends less time with her offspring after five weeks who emerged from the borough around four months By then they are fully covered in fur and may be around sixty seven percent the weight of an adult and eighty percent the length Juvenile males disperse further than females They are fully grown at around two years In separate publications in nineteen thirty four nineteen forty seven and nineteen fifty one William King Gregory theorized that placental mammals and marsupials may have diverged earlier and a subsequent branching divided the monotrees and marsupials Later research and fossil discoveries have suggested this is incorrect Modern monotrames are the survivors of an early branching of the mammal tree and a later branching is thought to have led to the marsupial and placental groups bothoth molecular clock and fossil dating suggests that the platyup was split from a kidnose around nineteen to forty eight million years ago The oldest discovered fossil of the modern Patypus dates back to about one hundred thousand years ago during the quadaterary period. Though a limb bone of Vornusaryynchus is known from paioceninee epic strata the extinct monotremes from the Cretaceous period. are considered to be basil to the platypus and echidas The remains of one were discovered in New South Wales. Composed of an opalized lower jaw bone with three molar teeth. The Mueller Tes were initially thought to be tribusphenic which would have supported a variation of Gregory's theory But later research has suggested that while they have three cusps They evolved under a separate process fossil jaw of another is elongated unlike modern platyupus inichidas blacks a be. Platypus has been a subject in the dreamt timee stories of Aboriginal Australians Some of whom believe the animal was a hybrid of a duck and a water rat Aboriginals from the Upper Darling River region have a story of a large water rack called Bagoon kidnaps a dog wander too far from its tribe After managing to escape, she returned and laid two eggs which hatched the first platypuses They were all exiled and wanted to live in the mountains. In another story from the Upper Darling The major animal groups land animals waterater animals and birds. all competed for the Patypos to join their respective groups But the Platypus ultimately decided to not join any of them feeling that he did not need to be part of a group to be special and wish to remain friends with all of those groups The Platpus is also featured as a totem for some Aboriginal peoples which is to them a natural object, plant or animal. that is inherited by members of a clan or family as their spiritual emblems And the animal holds special meaning for the Wandi Wandi people at the Murray River Because of their cultural significance and importance and connection to country The pllatypus is protected and conserved by these indigenous peoples Platipus is often represented Australia's cultural identity and its image has also been used for stamps and currency. and as a mascot in the two thousand summer Olympics in Sydney
