When and where to look
Platypus (Ornithorynchus anatinus ) and Australian water-rats (Hydromys chrysogaster ) are most likely to be observed early in the morning or late in the evening, though both animals may also be active in the middle of the day. Both platypus and water-rats occupy weir pools, irrigation channels and man-made dams or reservoirs as well as natural lakes, rivers, creeks, backwaters and billabongs. They are generally most readily spotted in places where the water surface is fairly calm, making it easier for observers to identify the ripples formed on the water surface as the animals swim and dive. Both species occur over a wide altitudinal range, from sea level up to at least 1500 metres. However, platypus are not commonly seen (and never abundant) in the salty water of bays and estuaries. In contrast, water-rats are known to inhabit ocean beaches and are found on many islands surrounded by sea water.
