Wild platypus attack in the antipodes. A case report.

The platypus (ornithorhynchus anatinus) is a furry duck-billed mammal that inhabits the waterways of eastern Australia. The male may reach 60 cm in length with a 20 cm beaver-like tail. We report the case of an American naturalist stung whilst trying to study the male in the wild. This resulted in an intense local reaction. Warning signs should therefore be erected at air and sea ports warning tourists of the dangers of these venomous Australians.
