The Platypus (Ornithorhynchus anatinus) is an iconic egg-laying mammal endemic to eastern and south-eastern Australia.
Where are Platypuses (also Platypi) found in Australia?
Platypuses are found in freshwater systems along the eastern and south-eastern coastline of Australia, including the island state of Tasmania. They are often sighted floating along the top of the river, looking for food, but are quite elusive so it often takes some time, patience and silence to catch a glimpse.
Along with the Short-beaked Echidna and Long-beaked Echidna (not found in Australia), the Platypus is a rare egg-laying mammal, called a monotreme.
What are the physical features of the Platypus?
There is no doubt - the Platypus is a strange looking creature. Covered in brown fur and featuring a bill, a big flat tail and webbed feet, the Platypus resembles something between a duck and an otter!
Males are approximately 25% larger, and have a poisonous spur their hind legs, which are thought to be used as a defensive tool to fend off competing males.
Platypus reproduction, gestation and birth
In general, breeding begins in late winter/early spring (August-September), however in northern Australia (see Cairns), breeding begins in winter (June-August), and in Tasmania, breeding begins later (November-January).
After a gestation period of just 21 days, the female will lay between one and three eggs (most common is two) and then incubate them in a nest in her burrow. After 10 days of incubation, the eggs will hatch and the mother will begin to feed them with milk through her mammary gland, which essentially secretes milk through the skin.
After three to four months in the burrow, the young will emerge.
The Platypus diet
The Platypuses bill, which is full of electroreceptors, assist it in finding molluscs, crustaceans and other invertebrates in murky water.
On the water surface, they will feed on insects (such as dragonflies and mosquitos) and water beetles.
Platypuses have also been observed feeding opportunistically on small fish, tadpoles, snails and worms.
The Platypus has been considered common across most of its range, however recent studies indicate that there is a growing list of declines and localised extinctions.
There are a couple of organisations in Australia who are doing some great work to support these fascinating creatures, including:
Best opportunities to see a Platypus
The best chance of seeing a Platypus is at dawn or dusk, and with an expert guide.
Where can I see the Platypus with an expert guide?
Tasmania, Australia’s island state, provides a rare opportunity to encounter unique and endemic wildlife. Renowned as a prime area for marsupial and monotreme spotting, Tasmania is a crucial habitat for many species, including echidnas, platypuses, quolls, kangaroos, wallabies, wombats and the most famous resident, the Tasmanian Devil.
