Platypuses are semi-aquatic and endemic to eastern Australia
Platypuses are semi-aquatic mammals endemic to eastern Australia. They are well adapted to their semi-aquatic lifestyle, with a streamlined body and a broad, flat tail covered in dense waterproof fur, which provides excellent thermal insulation. Platypuses are found in rivers, streams, and bodies of freshwater in eastern Queensland and New South Wales, eastern, central, and southwestern Victoria, and throughout Tasmania. They are active all year round, particularly at twilight and during the night, when they feed on a variety of aquatic invertebrates. Platypuses are one of the few venomous mammals, with male platypuses possessing a spur on the hind foot that delivers a painful venom.
The platypus is a unique Australian species and is one of the world's most remarkable animals. It is the sole living representative of its family Ornithorhynchidae and genus Ornithorhynchus. Platypuses are sometimes referred to as duck-billed platypuses due to their distinctive bill, which houses the ear openings and eyes, which close when diving. The platypus uses its bill to detect and sift small prey from the substrate, while larger prey is taken individually. They feed mainly during the night and can spend up to 12 hours per day underwater looking for food.
The diet of the platypus consists mainly of benthic invertebrates, such as insect larvae, as well as free-swimming organisms like shrimps, swimming beetles, water bugs, and tadpoles. Platypuses are largely solitary animals, but several individuals can share the same body of water. They are known to be reclusive, but they are also one of Australia's most recognised animals, often described as Australia's version of the otter. Platypuses are also featured on Australian postage stamps and the 20-cent coin, reflecting their iconic status in the country.
The conservation of platypuses is a growing concern due to the impacts of prolonged droughts, bushfires, changing climate, and deforestation on their habitat and population. Organisations like the Australian Platypus Conservancy are working to unlock scientific mysteries surrounding the species and are conducting conservation programs and environmental education initiatives to ensure the survival of platypuses in eastern Australia.

They are one of the only monotremes in the world
The platypus is a unique Australian species. It is one of the only monotremes in the world, along with the four species of echidna. Monotremes are a separate order of mammals that lay eggs instead of giving birth to live young. The platypus is the sole living representative of its family, Ornithorhynchidae, and its genus, Ornithorhynchus.
The platypus is a semi-aquatic mammal, endemic to eastern Australia, including Tasmania. It is present in eastern Queensland and New South Wales, eastern, central and southwestern Victoria, and throughout Tasmania. The species was once found in the Adelaide Hills and Mount Lofty Ranges of South Australia but is now extinct in that state, except for an introduced population on the western end of Kangaroo Island.
The platypus has a distinctive appearance, with a broad, flat tail and a duck-like bill. Its body is covered with dense, waterproof fur, which provides excellent thermal insulation. The platypus is well-adapted for its semi-aquatic lifestyle, using its webbed limbs to propel itself through the water and its tail for fat storage. It feeds mainly on aquatic invertebrates and has a sense of electrolocation, which it uses to detect prey in cloudy water.
The platypus is a solitary animal but can share the same body of water with other individuals. It is most active during twilight and at night, foraging for food for up to 12 hours per day. The platypus is an iconic Australian animal, featuring on the country's 20-cent coin and postage stamps. However, its population is declining due to prolonged droughts, bushfires, changing climate, and deforestation.

Platypuses are venomous and lay eggs
The platypus is a semi-aquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. Platypuses are one of the few venomous mammals in the world. The male platypus has a spur on the hind foot that delivers an extremely painful venom.
When the platypus was first encountered by Europeans in 1798, a pelt and sketch were sent back to Great Britain by Captain John Hunter, the second Governor of New South Wales. British scientists initially believed the attributes were a hoax. They thought someone had sewn a duck's beak onto the body of a beaver-like animal. George Shaw, who produced the first description of the platypus in the Naturalist's Miscellany in 1799, stated it was impossible not to doubt its authenticity.
The platypus is the sole living representative of its family Ornithorhynchidae and genus Ornithorhynchus. Together with the four species of echidna, it is one of the five extant species of monotremes, 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 cloudy water. It is one of the few species of venomous mammals.
The female platypus lays her eggs in an underground burrow that she digs near the water's edge. Baby platypuses hatch after 10 days and nurse for up to four months before they swim off and forage on their own. The platypus is largely a solitary animal, but several individuals can share the same body of water.

They have been depicted on Australian coins and postage stamps
The platypus is a unique Australian species. It is a semi-aquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. Platypuses are grouped in a separate order of mammals known as monotremes, which are distinguished from all other mammals by their egg-laying ability. The platypus has been depicted on Australian coins and postage stamps, reflecting its significance as a native Australian animal.
The embossed image of a platypus has appeared on the reverse (tails) side of the 20-cent coin since the introduction of decimal currency to Australia in 1966. Designed and sculpted by Stuart Devlin, the platypus design celebrates the unique wildlife of Australia. The 20-cent coin has also been used for commemorative designs, showcasing the platypus as a symbol of Australia.
The platypus has also been featured on Australian postage stamps, further emphasising its importance in Australian culture and history. The most recent appearances include the 2015 "Native Animals" series and the 2016 "Australian Animals Monotremes" series. These stamp series celebrate the diversity of Australian wildlife and recognise the platypus as an iconic species within the country.
Additionally, the Australian Platinum Platypus Coin, made of pure platinum, is another example of the platypus' presence on Australian currency. This coin is particularly popular among collectors due to its rarity and value. The design captures the essence of the "duck-billed platypus," highlighting its distinctive features and natural habitat.
The depiction of the platypus on Australian coins and postage stamps not only showcases the country's unique wildlife but also helps raise awareness about conservation efforts. The Australian Platypus Conservancy, for example, works diligently to unravel scientific mysteries surrounding the species and conducts various conservation programs and environmental education initiatives. By featuring the platypus on currency and stamps, Australia promotes the recognition and preservation of this remarkable animal.
