The document discusses five animals and the biomes they live in: desert tortoises live in deserts and have waterproof skin, caribou live in taiga and search for food while being hunted by wolves, red foxes live in forests and hills and eat mostly rodents unseen by humans, great blue herons live in wetlands where they fish and nest in trees with long necks and bills adapted for fishing, and grizzly bears live in mountains as omnivores eating plants, animals, fish and berries and hibernating in winter.
