Platypuses

The platypus is sometimes known as a "duck-billed platypus", but this is a misnomer, as its bill serves a function quite different from that of a duck.

A platypus is a monotreme, i.e. an egg-laying mammal. It has dense, waterproof fur and a thick, beaver-like tail, but that is its only resemblance to a beaver.

It has short legs with webbed feet, and is well-equipped to hunt in the water, yet spends most of its time on land. Each foot has five toes with sharp claws, as it digs a burrow in the riverbank for shelter. When swimming, a membranous "web" extends between the toes. The male platypus has a venomous spur on its hind leg, which cannot kill a human but can cause extreme pain.

The platypus is shy and nocturnal, active mostly at dawn and dusk. It hunts for food underwater, using its duck-like bill, which is equipped with extremely sensitive electroreceptors to find food such as insect larvae, snails, worms, small fish, and crustaceans. It can remain underwater for between one and five minutes.

The platypus is found in freshwater creeks and rivers in eastern Australia, from sub-alpine regions in Tasmania north to the sub-tropical zone of north Queensland.

The platypus and the echidna are both monotremes, or egg-laying mammals. this is a unique classification of mammals, with only three known species: the platypus, the short-beaked echidna (both of Australia) and the long beaked echidna (of New Guinea).

There is only one type of platypus, ornithorhynchus anatinus, and it is not endangered. The platypus is natve to Australia, and the Australian Government lists the platypus as "common but vulnerable". The International Union for Conservation of Nature (IUCN) lists the platypus as "least concern".

They are both mammals and both have tails.

Platipuses drink milk, like all mammals, whilst they are infants.

No, male roosters (also known as cocks) cannot lay eggs. Only female chickens, known as hens, are able to lay eggs. Roosters are generally larger and more colorful than hens, and they have a characteristic comb and wattle on their head. They are used for breeding and for showing, but they do not have the ability to lay eggs.

Platypuses, especially small ones, can be eaten by a variety of predators including spotted-tailed quoll, dingo, feral cat, goannas, water rats, owls and pythons. The platypus is midway in the food chain. Whilst there are other animals that prey upon this creature the platypus, in turn, is carnivorous and preys on small crustaceans, larvae and fish that live underwater.

Within its niche in creeks and rivers, the platypus is the top predator; below it are the shrimp and small crustaceans upon which it feeds; they, in turn, feed on zooplankton, which feed on phytoplankton.

Platypuses are also occasionally taken on worm-baited fishing lines and become entangled in discarded mesh and nylon. See the Related Link.

No, platypuses live in inland freshwater environments in mainland Australia, not in the ocean.

Although platypuses can live in wetlands, this is not one of their preferred habitats. platypuses prefer freshwater creeks, rivers and lakes where they can dig burrows in the banks above the waterline. Wetlands do not usually provide this higher ground for burrows, where platypuses can remain dry when they are not hunting for food.

It is described as a "1940's fedora".

If you mean Platypus, they are native to Australia and Tasmania

Newzeland was so isolated that from the time of its formation till the arrival of man the only animals to get to it were those with wings. Insects, birds and bats.

Marsupials and monotremes never made it to the island

The platypus has a unique combination of both mammalian and reptilian features, and the way its respiratory, digestive, nervous, and circulatory systems work together is no exception. Its respiratory system consists of two lungs and a rudimentary form of a larynx, enabling the platypus to breathe air. The digestive system begins with the mouth, where the platypus' beak-like bill grinds and breaks up food into small particles. The food then travels to the esophagus, stomach, and intestines, where it is broken down further and nutrients are absorbed. The nervous system is composed of the brain and spinal cord, and it is responsible for controlling movement and sensation. The platypus' circulatory system consists of a heart, arteries, and veins, and is responsible for transporting oxygen and nutrients throughout the body. All of these systems work together to enable the platypus to survive and thrive in its environment.

Platypuses are carnivores. They are predators; they eat small water animals such as aquatic insect larvae, fresh water shrimp, annelid worms, yabbies and crayfish. During summer, they eat more than during winter, in order to build up reserves of fat.

To catch their prey, platypuses must make several hundred dives a day in order to catch enough food. They use the fine, sensitive electroreceptors on their bills, which detect the tiny electrical impulses made by underwater creatures. After locating their prey, they dig up the mud with their bill to grasp them, crushing the creatures between grinding plates in their bills.

Baby platypuses drink mother's milk.

No. Platypuses are air-breathing mammals, which use their lungs to breathe. Most times, they stay underwater for just one to two minutes. However, if a predator threatens, the platypus is able to stay underwater, motionless, for up to eight minutes, holding its breath.

platypuses DO NOTFLYSO SHUT UP

The platypus is uniquely adapted to live in a semi-aquatic ecosystem. It is found in freshwater creeks and rivers, within bushland, alpine or sub-tropical areas.

The ecosystem helps the platypus survive because it provides the food this animal needs. The platypus dives into creeks and rivers for its food. Its bill has sensitive electroreceptors which pick up tiny nerve and electrical impulses generated by crustaceans and other animals that inhabit the bottom of the creek or river. The platypus then uses its bill to shovel away the dirt, and find the food. It does not have teeth, but hard bony plates which it uses to grind the food.

The platypus has webbed feet which help it to swim, and which have a retracting webbed membrane which can expose the claws, enabling the platypus to effectively dig burrows in riverbanks for shelter, and the webbing membrane retracts for that purpose, but spreads between its toes when it needs to swim - which it needs to do to get its food.

During mating season, the female platypus digs a separate chamber at the end of her burrow. The eggs are laid here, and once hatched, the mother "closes off" the chamber with a wall of leaves when she leaves, to protect the young. The wall of leaves is also designed in such a way that it helps remove excess water from the platypus when she returns, thus keeping the chamber as dry as possible.

There is no need for anything in particular to be done to help the platypus's population. While there was a time when it was under threat, being particularly prized for its fur years ago, its numbers have returned to essentially the same levels they were prior to European settlement. The Australian Government lists the platypus as "common but vulnerable". The International Union for Conservation of Nature lists the platypus as "least concern".

The platypus now has protection by law in the National Parks and Wildlife Act of 1974 (from hunters and fishermen), and the population has grown back to a healthy size. Another issue was that platypuses were drowning after being caught in fishing nets. it is no longer legal to use fishing nets in freshwater rivers and creeks.

There are concerns regarding the destruction of their habitat and awareness of this problem is increasing. Being officially protected means the platypus may not be hunted, or specimens taken as pets, and there are strict laws even governing the keeping of platypuses by wildlife sanctuaries or zoos. Currently, in 2013, no zoos outside of Australia have platypuses.

Tasmanian platypuses are subject to a disease caused by the fungus Mucor amphibiorum, which has fortunately not migrated to the mainland. Affected animals often develop skin lesions or ulcers, and the biggest threat to their survival arises from secondary infection. This can affect the platypus's ability to maintain body temperature and to hunt properly for food on the bottom of rivers and creeks. Naturally, funds are being directed into finding causes and cures for the problem.

Pythons and goannas eat platypus eggs. The female platypus will actually place earthen plugs along the length of her burrow before the chamber which holds the eggs, in order to deter such predators.

Both. Platypuses live throughout eastern coastal Australia and its island state of Tasmania, particularly within heavily wooded and protected regions, from the cooler sub-alpine areas in the south and the Tasmanian highlands to tropical far north Queensland.
