Three diverse sea creatures – all endemic to the Galápagos – form a harmonious neighborhood at the base of this cliff on Eden Island. The marine iguana is the only species in the world that lives on land yet feeds in the ocean. These cold-blooded reptiles regularly bask in the sun to regulate their body temperature. Sea lions haul-out to rest after extensive hunts below the water. And the Sally Lightfoot crabs eats algae cast ashore by turbulent waves. What a symbiotic relationship.
