Caption: This image depicts marine life during the Cambrian explosion (~520 million years ago). A giant Anomalocaris investigates a trilobite, while Opabinia looks on from the right, and the "walking cactus" Diania crawls underneath. All these creatures are related to living arthropods (creatures with exoskeletons and jointed appendages, such as insects, arachnids and crustaceans).
