Overview

LOCATIONEastern AustraliaTasmaniaThey live near freshwater lakes and rivers.

Habitat

Duck-Billed Platypuses are found in the lakes, streams and rivers. They build their burrows in banks, with theentrance being approximately 30 cms (12 inches)above the surface of the water._They have territories of up to 7 kms (4.4 miles) and the territory of a male will overlap withthe territories of 3 - 4 females.

SIZE AND COLORBody is 14 inches longTail is 5 inches longMales are usually slightly larger than females.it weighs about 3 lbshas a fur it`s Colors vary from yellowish to dark brown.

FOOD

They are (carnivore).they eat primarily aquatic invertebrates in streams and lakesWorms.Fish. Tadpoles. Frogs. Crustaceans.

AdaptationThe platypus is a highly unusual animal for a number of reasons :

1_ It is one of only two mammals to lay eggs (the other being the echidna).2_ it is one of only two species of mammal capable of envenomating (the other being the shrew) and it has a beak. It is highly adapted in a number of other ways, too, and is truly a strange product of its environment.

AdaptationEgg LayingEgg laying mammals are called monotremes, and there are only five species that do so -- four of which are echidna. Little fossil evidence of monotremes exists, but scientists believe that before evolving to deliver live young, most mammals laid eggs. In that regard, the platypus is a historic relic.

Poison Spur Male platypuses have a spur on each foot, from which they can deliver a venomous sting. This capacity to deliver poison is extremely rare for mammals. Shrews are capable of doing it, too, but the platypus is the only creature on Earth to have a venomous spur.

AdaptationDuck BillThis feature enable the platypus to hear and breathe while diving for prey.It is remarkably similar to a ducks bill, hence the name, but it most likely evolved independently of the duck, despite this similarity.

Strong ClawsAs well as being good at swimming, platypodes are good diggers. They have adapted to have strong, shovel-like claws that enable them to move and disturb thick, heavy soil and mud. They dig in order to burrow. This is especially important for females, who use a nesting burrow for raising their young.

AdaptationFat TailThe platypus tail is fat and flat. Its flatness assists with swimming,functioning almost like a rudder. But the tail is also a fat store. this adaptation is especially important for females, who require stores of fat for nesting in their burrow. However, males store fat as well, for periods when they are unable to find food.

Webbed FeetPlatypuses have evolved to have webbed feet. The webs enable them to swim more efficiently and move around on soft,muddy surfaces with ease. The front feet are fully webbed, the hind feet are only partially webbed.

duck billed platypus life cycle-How the platypus finds a mate is the male produces a musky odor during the breeding season.~It reproduces by laying eggs, which hatch into young platypuses that initially feed off of mother's milk.~The gestation period for a platypus is 2-3 weeks.~The platypuses take care of their young by feeding them their mother's milk which is secreted from her pores and collects on grooves in her abdomen.~The offspring leaves the burrow and their parents when they reach approximately 4 months old.

The life cycle of platypus

Babies

Females usually lay two soft, leathery eggs but may lay up to four.She clasps the eggs against her abdomen with her tail for about two weeks.Milk is produced by glands under mothers skin, and the baby licks milk from her fur.

A fact: There is a higher proportion of spur wounds in males than females, which may be explained by aggressive encounters between males during mating season.

Their FeaturesHave no furBlind for about two monthsHave teeth for a short timeHelpless

Relationship to humanPlatypuses are shy animals which avoid contact with humans as much as possible. Humans have had considerable impact on platypuses in the past, such as killing platypuses for their fur, or using fishing nets in rivers which caused entangled platypuses to drown as they could not come to the surface to breathe.However, now the platypus is a protected native species. They are elusive creatures, rarely even studied by scientists, as research can be too intrusive in their environment.
