Fish do it, frogs do it, pythons, eagles and elephants do it, yet “poop” is one of those subjects we find difficult to talk about with a straight face.

Excrement is also a scientific detective puzzle, since much can be learned about an animal from what it leaves behind. May 28 through September 4, 2016.
