A curious Platypus (Ornithorhynchus anatinus) just surfaced in Meander river near the town of Deloraine, Tasmania. 

The Platypus (Ornithorhynchus anatinus) in this lake in Victoria were very shy. When they came to the surface they quickly dissappeared again even if we just made a small sound. 

European Perch (Perca fluviatilis) is an invasive species introduced here around 1861. The Perch is considered a pest as it eats all the small native fish. This photo was taken in the Meander river near the town of Deloraine, Tasmania.

Another invasive species is the Brown Trout (Salmo trutta). This species was introduced from the United Kingdom in 1864. The predator is also foraging on the small native fish. This photo is from Victoria, Australia.

The Tasmanian Native-Hens (Tribonyx mortierii) diet mostly consists of grass shoots and the leaves of low herbs which it grazes during daylight hours. This photo was taken in Craddle mountain in Tasmania.

A Platypus habitat in the central Tasmania. Habitats are very diverse. They seem to be common in both fast flowing rivers and slow moving rivers. Even still water lakes.
