Duck-billed platypus
The platypus is a species that combines many features of other species such as the flat tail of a beaver, webbed feet like a seal and an oversized duck bill. The platypus and the porcupine are the only two mammals on the planet that lay eggs. Both species are native to Australia. The rivers and lakes of Southeast Australia are ideal places to see platypus. Platypuses are very shy and nocturnal.
