The giant panda's distinct black-and-white markings have two functions: camouflage and communication. Most of the panda - its face, neck, belly, rump - is white to help it hide in snowy habitats. The arms and legs are black, helping it to hide in shade. Like domestic cats, giant pandas have vertical slits for pupils.
Giant pandas spend 10-16 hours a day feeding, mainly on bamboo. Pandas need at least 2 different bamboo species in their range to avoid starvation. Although pandas are 99% vegetarian their digestive system is typical of a carnivore. For the 1% of their diet that isn't bamboo, pandas eat eggs, small animals, carrion, and forage in farmland for pumpkin, kidney beans, wheat and domestic pig food.
