Detailed explanation-1: -Darwin noticed that different tortoise species lived on islands with different environments. He realized that the tortoises had traits that allowed them to live in their particular environments. For example, tortoises that ate plants near the ground had rounded shells and shorter necks.
Detailed explanation-2: -Saddleback Tortoise Characteristics: Saddle-shaped, flat carapace, long neck, larger distance between plastron and front of the carapace, which is angled upwards, smaller in overall size, yellowish color on lower mandible and throat.
Detailed explanation-3: -ABOUT. Adapting and surviving: Galápagos tortoises are the giants of the tortoise world. Males can weigh more than 500 pounds (227 kilograms), and females average about 250 pounds (113 kilograms). They have thick, sturdy legs to hold up all that weight, but they still spend a lot of time lying down to conserve energy.
