Galapagos Reptiles Galapagos Reptiles: Tortoises, Lizards, Marine Igu

When it comes to land animals, the Galapagos Islands reptiles reign supreme. Unlike much of the world, where mammals are the dominant species, the Galapagos reptiles have taken center stage thanks to their unique ability to survive long periods without water. This adaptation allowed them to make the epic 620-mile journey across the Pacific from mainland South America to the volcanic islands.
Visitors to the Galapagos will quickly discover that reptiles are deeply tied to the islands’ identity. Even the name "Galapagos" comes from the Spanish word for saddle, inspired by the shell of the giant tortoise—arguably the most famous Galapagos reptile and a mascot for the archipelago. From giant tortoises and marine iguanas to unique geckos and snakes, the islands are home to a remarkable diversity of reptilian life.
A trip to the Galapagos promises unforgettable wildlife encounters, with reptiles playing a starring role. Below is an overview of some of the most iconic Galapagos Islands reptiles and where travelers can see them.
