Not only does the platypus "have feet like a duck but it's furry," (remember that commercial from the 80s?) it also has venomous spurs on it's hind feet that inject predators (and possibly other male platypuses competing for the same mate) with poison strong enough to kill small animals and cause extreme pain to humans.  So the next time you're in Australia and come across one of these egg-laying, duck-billed, beaver-tailed, otter-footed mammals, don't pick it up. 

That's the most interesting new thing I've learned in quite some time. #nature
