Biology does whatever it can do, and it's usually pretty messy about it. Just when people think they've figured out a nice hierarchical system for classifying plants and animals and microscopic organisms, we find out that there's more going on and some things aren't as clear cut as we thought.

in the future. If you thought a platypus was weird, check out a few of these creatures.
