Another resident of Eden Island you may encounter is the Galápagos land iguana. This unattractive lizard is endemic to seven central islands of the Galápagos. There are three unique species. This one is probably conolophus subcristatus. Yet each reptile’s colorization matches its environment. Notice how his scaly skin blends into the surrounding lava rock. These animals can grow to five feet long and weigh up to 25 pounds.
