Marine iguanas on the Galapagos islands have adapted to deal with huge waves, cold waters and limited food supply. The females feed only on the nearby rocks, but the larger males can dive up to 10 metres to reach the best seaweed. They stay underwater for a short amount of time before they need to return to shore to warm up again. The females must travel inland away from the coast to lay their eggs, but this poses its own dangers, as they are exposed to hungry predators.
