The platypus is one of the most unique animal species from a continent on planet Earth that is already known for its one-of-a-kind diversity. A semiaquatic, egg-laying mammal, the platypus is the last living member of its family and genus, with all other related species extinct. The platypus has been a popular figure on Perth Mint coinage since its introduction on platinum coins.
The platypus is one of the most recognizable creatures from the Australian continent and an iconic symbol of the nation. The platypus is also important within the history of the Aboriginal Australians as it was once a primary food source for tribes, though the animal is now a protected species that is considered near-threatened.
