Animals

Giraffe drink water if it is available but can go weeks without it; they rely on the morning dew and the water content of of their food. Their very long necks are an adaptation to feeding at high levels in the treetops. The neck veins contain valves and a network of tiny veins (rete mirabile) to prevent blackouts when the animal lowers its head to drink. In addition to keeping track of predators, their extreme long-range visual acuity enables visual communication with other giraffe over several miles. Giraffe can run at speeds up to 35 mph.
