The coelacanth, a prehistoric fish that was mistakenly thought to have gone extinct at the same time as the dinosaurs, has managed to stick around our seas for 360 million years. Erin Eastwood details the surprising "back from the dead" discovery of the coelacanth and explains how this fish's fins shed light on the evolutionary movement of vertebrates from water to land.
