Galapagos tortoises have two very different shapes, each adapted for different feeding habits needed on low, arid islands versus high, lusher islands.

Tortoises with dome-shaped shells live on islands where there is an abundance of vegetation close to the ground, making it less necessary for the animals to raise their heads to feed.

Some tortoises, have shells that rise in front, like a saddle. This adaptation makes it easier for them to lift their heads high to eat tree cactus and to resolve disputes over limited food resources, which they do through raising their heads as high as possible during social interactions

Isabela Island is the 4th stop on the tour. The entry should describe the different shells of giant tortoises found on the island. Information on the Galápagos Giant Tortoise is given in the reading and  video excerpt from “Galápagos: Born of Fire”.
