Giant Galapagos tortoise enjoys relaxing in the mud

Galápagos tortoises lead an uncomplicated life, grazing on grass, leaves, and cactus, basking in the sun, and napping nearly 16 hours per day. A slow metabolism and large internal stores of water mean they can survive up to a year without eating or drinking. Tortoises lay eggs. Females lay their eggs in nest holes, which they cover and leave. Babies hatch in four to eight months. They are on their own from the beginning.
