"The platypus may be one of the strangest mammals in the world. Not only do these mammals lay eggs (just like all other monotremes) they also have a bird-like bill and they don't have nipples! They don't have teeth either (at least as adults)! The platypus is from Australia and is considered an aquatic mammal: it spends a lot of its time in water." Via Animal Fact Files.
These animals burrow using long claws on their super cute and super functional flippered feet. They're a little awkward walking on land, but they get by: they walk on their knuckles! It's pretty darn cute, but also awkward, like the platypus. The platypus was nearly extinct 100 years ago, but today they're making a comeback with protections that are in place. Look out world!
