The duck-billed platypus ( Ornithorhynchus anatinus ) is one of the most unusual creatures in the fauna kingdom . The platypus has a boat paddle - shaped tail , like abeaver ; a streamlined , furry dead body , like anotter ; and a matte bill and net base , like a duck’s egg . In fact , the first time a stuff platypus was brought from Australia to Britain , people could n’t think it was a existent animal ; they thought a trickster had sewn two animals together , according to London’sNatural History Museum .
Platypuses ( which is the right plural variety , not " platypi " ) are among the few virulent mammals . Males have a prod , connected to a malice - release gland , on each hind understructure . More venom is secreted during mating season , leading investigator to think that the spur and maliciousness help male person compete for mates , according to theAustralian Platypus Conservatory . The venom is not life - threaten to humans , but it can do life-threatening hump and excruciating pain .

Size and appearance
Adult male platypuses can range between about 15.7 inches to 24.8 inch ( 39.8 to 62.9 cm ) long , from the tip of the bill to peak of the behind , fit in to theAustralian Museum . grownup female range from 14.5 to 21.6 inch ( 36.8 to 54.8 cm ) long . grownup males consider about 1.7 to 6.6 lbs . ( 0.8 to 3 kilograms ) and females weigh about 1.3 to 3.7 lbs . ( 0.6 to 1,7 kg ) .
scientist have institute fossil that suggest that ancient platypuses were significantly larger than the forward-looking variety , at about 3.3 metrical unit ( 1 measure ) long , Live Science previously report .
Platypuses have dense , slurred fur that helps them stick around warm underwater . Most of the pelt is dark brown , except for a eyepatch of lighter fur near each oculus and light - colored fur on the underside . Underultravioletlight , however , duckbill ' drab brown fur glows green and puritanic , Live Science antecedently report . It ’s possible that this biofluorescence helps cut the animate being ' visibility to piranha , but the eery glow may suffice little or no bionomic mapping . scientist are still enquire this interrogation .
A platypus ’s front ft have supererogatory tegument that acts like a paddle when the animal is swimming . When platypuses are on Edwin Herbert Land , their webbing retracts , making the claws more pronounced , according toNational Geographic . The creature walk on their knuckle duster to protect the webbing , harmonise to a 2001 report in theJournal of Experimental Biology .
The government note of a platypus resembles that of a duck and has a bland grain that feels like suede cloth . It is also pliant and rubbery . The skin of the broadsheet hold tens of thousands of sensory receptors that help the platypus navigate underwater and find motion of potential food , such as runt , concord to the Australian Platypus Conservatory .
Venom
Male duckbill post maliciousness secretory organ , locate near their pelvic girdle , that plug in to hollow goading on their hind leg , according to ablog compose by Bianca op hideout Brouw , a toxinologist at the University of Melbourne in Australia . vernal females also have these spurs , but they drop off them in the first class of life .
The maliciousness glands of grownup males fluctuate in size throughout the year , reaching their maximum size of it during breeding season , when males use their malice to contend for mates . To shoot its maliciousness , a male wraps its legs around its victim and drives the spurs through the animal ’s build , accord to op den Brouw .
The venom itself contains a cocktail of more than a XII protein that go to three major category of toxin , op den Brouw wrote . This venom is not lethal to platypuses or humans , but it make swelling and excruciating pain , and it can cut off wound healing and the function of cell membranes , she remark . In humankind , the hurting from a platypus bite can be address with nerve blocker , which block specific cheek cellular telephone from sending signals to thebrain .
Habitat
platypus inhabit in Australia in a range that extend from westerly Victoria to about as far north as Cooktown in Queensland , imply they occupy a gravid stretch of the east and southeast coast of the commonwealth , accord to theAustralian Platypus Conservatory . The creatures can also be found on Tasmania and King Island , as well as on Kangaroo Island , where platypuses were introduced by humans in the early 1900s .
Platypuses occupy freshwater systems — including river lavatory , lakes , ponds and streams — throughout their habitat stove . The animals expend about 10 to 12 hours a Nox in the water , hunting for food ; they are most participating during nighttime and dusk , because they are nocturnal . They can stay underwater for only 30 to 140 second , the Australian Museum notes .
During the day , they hide out out in burrows on the shoring , where earthen tunnels open up into ellipse - mold secret Sir William Chambers , agree to theSan Diego Zoo . duckbilled platypus also take shelter under rock ledge , antecedent and debris , according to the Australian Platypus Conservatory .
Though they exist on only one side of one continent , platypus brave out many climatic extreme . They have been found in plateaus , lowlands , tropic rainforests , and the cold raft of Tasmania and the Australian Alps . platypus ' raincoat , thick fur keeps them tender in chilly atmospheric condition , and their big fundament stack away extra fatty tissue for vitality , harmonise to the Australian Platypus Conservatory .
Diet
Platypuses are carnivorous , which imply they eat meat but not plant . They hunt for their food for thought in the water where they endure . As they swim , they detect intellectual nourishment along the boggy bottom of the river , stream , pool or lake using only their tender bill , since the creature in reality close their eyes , ears and nostrils while foraging underwater , according to the Australian Museum .
When platypuses find something interesting , like insect larvae , they take up it up in their handbill , put in it in their cheek pocket and drown to the Earth’s surface . The animals also eat shrimp , swim beetles , water bugs and tadpoles , as well as the occasional worm , freshwater pea mussel or escargot . Platypuses have even been observed eating cicadas and moths that they catch at the water ’s open , according to the Australian Museum .
After occur up from a dive , platypuses drift atop the water supply and jaw their food using " grinding plates " in their mouths . The animals sometimes pick up mud and sand in their impertinence pouch , and as they eat , they expel this inedible sediment , along with spare water , through grooves in their small jaw , according to the Australian Platypus Conservatory .
Baby platypuses
Most mammals give birthing to hold out young . Platypuses , however , lay eggs . Mammals that lay egg are recognize as monotremes , and besides the platypus , the only other egg-laying mammal areechidnas , or spiny anteaters , according to the University of Melbourne . Echidnas are incur only in Australia and New Guinea .
When distaff platypuses are ready to have their untested , they tunnel inside the primer coat on the riverside and seal off themselves into tunnel rooms . Each female person then lays one to three ballock and places them between her tush and her fanny to keep them warm . After about 10 days , the eggs hatch and the bean - sizing babies nurse for three to four month inside their tunnel , according to the Australian Museum .
Around the time of weaning , babe duck-billed platypus can swim on their own , according to the Australian Platypus Conservatory .
Taxonomy
Here is the taxonomy of the duck-billed platypus , according to theIntegrated Taxonomic Information System(ITIS ):
Conservation status
duck-billed platypus are not endangered , but theInternational Union for Conservation of Nature(IUCN ) lists them as " near threatened , " meaning the metal money may be vulnerable to experimental extinction in the approximate future but does not presently qualify as threatened .
The duckbill was first listed as nigh imperil in 2016 after scientist observed a decline in the species ' overall number , " although the decline is badly define and discrepant across the duckbill ’s range , " the Australian Platypus Conservatory notes on its web site .
