| | Digimorph - Ornithorhynchus anatinus (duckbill platypus) |
 | | Ornithorhynchus anatinus, the duckbill platypus, is a unique mammal native to Queensland, New South Wales, Victoria, South Australia, and Tasmania, where it frequents freshwater streams, rivers, lakes, and lagoons. |
 | | It is not difficult to understand why early European explorers were initially puzzled with the classification of the platypus. |
 | | Moreover, few studies are based on serial sectioning and concentrate on its internal cavities (Pritchard, 1881; Wilson and Hill, 1908; Watson, 1916; Zeller, 1989a, b) and these data have yet to be incorporated into systematic analysis. |
