They Came from the Sea. In an invasion more reminiscent of a sci-fi movie, millions of crabs have been leaving their watery habitats to take up residence on land. For 35 million years - a short period in evolutionary terms - they have been developing their survival skills, adapting themselves to unusual and hostile environments from deserts to suburban lawns, and even in trees. Filmed across the world and using macro-filming techniques to give an intimate view of the crabs' world,
Wildlife on One examines the reasons behind this assault on terra firma and explores the problems crabs will have to solve if they are to become true terrestrial creatures.
