Roly polies or pill bugs? No matter what you call them, these organisms are unique. Biology scholars discover a true evolutionary success story in a video about tiny, land-dwelling crustaceans. The narrator describes their journey from sea to land, identifies the structures that link them to shrimp and lobsters, and shows how the rotting log or stone you'll find them under is all that keeps them breathing.
