Galapagos Marine Iguana slowly walking into the sun. Some fun facts about marine iguanas! They are endemic to the Galapagos (only found in the Galapagos) They can hold their breath under water for 1 hour. Their bodies shrink and grow depending on the food supply. They look like mini dragons and they are super chilllllll. #Galapagos #marineiguana #iguana #isabela #islandlife #vacation
