A magnified image of the area near equator close to South America shows some small islands which are a part of the Galapagos island. The islands, Isabela and Hood are marked. The photographs of 2 tortoise are captioned as:

1. Isabela Island Tortoise: Tortoises from Isabela Island have dome-shaped shells and short necks. Vegetation on this island is abundant and close to the ground.
2. Hood Island Tortoise: The shells of Hood Island tortoises are curved and open around their long necks and legs. This enables them to reach the island’s sparse, high vegetation.
