ocr: Deer Deer used to be found only in Asia, but now they have spread throughout the world. Deer species include cold-dwelling animals like moose, elk and caribou as well as woodland species like the European roe deer, red deer and fallow deer. Deer are swift runners, and they need this speed to evade predators. These animals have special stomachs which help them digest and gain nourishment from tough leaves and grasses.
