Gold Medalists of the Natural World:
Marine Iguana (Amblyrhynchus cristatus)
Event: triathlon
You won’t see this species riding a bike, but the Galapagos marine iguana is the only lizard in the world that you will see running on land and swimming beneath the ocean waves. In pursuit of marine algae to eat, large males are capable of swimming to depths of 20m and staying underwater for 30 minutes. After feeding in the cold seawater, marine iguanas sunbathe on land to warm up again
