Did you know?

Many herbivorous animals, such as rabbits, deer, sheep, and cows, are noted for their gentle and passive ways. But such behavior is not universal among herbivores. Rhinoceroses and elephants, for instance, are capable of inflicting serious damage if threatened, and among dinosaurs, the herbivorous Diplodocus had a thick tail that could be used as a lethal weapon against attacking carnivores. Herbivorous humans are usually called vegetarians.
