Santa Cruz Island is home to the second largest population of giant tortoises in Galapagos. They are dome shaped because they have evolved on this Island where food is plentiful on the ground, in comparison to their relatives with saddleback shapes in places where food is much higher and harder to reach – an impressive fact about how populations are different from island to island. This is just another example of adaptive radiation on the archipelago.
