@stemtut: Over 500 million years ago, Earth’s oceans were home to creatures that looked more alien than anything in science fiction. Opabinia regalis had five eyes, a backwards-facing mouth, and a flexible trunk ending in a claw like something nature made on a dare. Discovered in the British Columbia, Canada, this tiny predator reminds us how wildly experimental early evolution really was. #Opabinia #Cambrian #PrehistoricLife #AncientOceans #Evolution
