Basking buddies. Marine iguanas, Galápagos Islands, Ecuador
Marine iguanas, seen in today's image, are fascinating creatures found exclusively on the Galápagos Islands in Ecuador. They weigh around 1.5 kilograms and can grow up to 1.5 metres in length. These reptiles are the only lizards in the world that forage in the sea, diving to graze on algae growing on submerged rocks. Researchers believe that both Galápagos land iguanas and marine iguanas evolved from a common ancestor that likely rafted from Central or South America. They've adapted in remarkable ways, from flattened tails for swimming to salt glands that allow them to expel seawater by sneezing.
Their dark colour helps them absorb heat quickly after swimming in the cold waters. These reptiles are not very social; they are often seen sunbathing in groups to conserve heat, especially during cold nights. Visiting the Galápagos Islands is a unique chance to see marine iguanas in their natural home. Whether you're swimming with them or watching them sunbathe on the rocks, it's an experience you'll never forget.
