### Identification The Platypus is a biological mosaic: a streamlined, torpedo-shaped body covered in dense, dark-brown waterproof fur, ending in a broad, paddle-like tail. Look for the iconic leathery, duck-like bill—which is soft and sensitive, not rigid like a bird’s. Adults typically measure 40–50 cm. In the water, look for a distinct "V-shaped" wake. To avoid confusion with the Water Rat (Rakali), check the tail; the Rakali has a white-tipped, cylindrical tail, while the Platypus’s tail is flat, dark, and beaver-like.
### Habitat & Range Endemic to eastern Australia and Tasmania, this monotreme frequents freshwater systems ranging from cold alpine streams in the Great Dividing Range to lowland tropical rainforest rivers. They require earthy banks for burrowing, often sheltered by overhanging vegetation like weeping callistemon or tree ferns. While they prefer pristine rivers, they are surprisingly resilient, occasionally appearing in suburban creeks and farm dams.
### Behaviour Primarily crepuscular, the Platypus is most active at dawn and dusk. You’ll likely spot one diving repeatedly; they spend about 10–12 hours a day foraging. They are solitary and shy; at the slightest vibration or sound, they vanish with a characteristic splash. During breeding season (winter/spring), females retreat to long, complex nesting burrows to lay two leathery eggs, which they incubate against their warm bellies.
### Diet The Platypus is a bottom-feeder, diving to the riverbed to scoop up benthic invertebrates—shrimp, crayfish, and insect larvae (like caddisflies). Because they lack teeth, they store prey in cheek pouches along with grit, surfacing to grind the meal between horny keratin plates before swallowing.
### Fascinating Fact If you were to shine a UV light on a Platypus in the dark, its brown fur would glow a vivid blue-green. This biofluorescence was only recently discovered, and while its purpose remains a mystery, it adds another layer of magic to this already "impossible" creature.
