Herbivores need to eat plants to survive. They often have high health and low speed. Some herbivores can output fairly good damage, and a fairly good amount of stamina to run away if needed. A few herbivores also have a high amount of defense, like the Ankylosaurus. Unlike Carnivores these animals cannot eat meat. Herbivores also often form herds that are (more often than not) used as a survival tactic to fend off any predators looking for a meal.
Herbivores also have some of the slowest dinosaurs in the game, these including the adult Barosaurus and adult Breviparopus. These dinosaurs can also be arguably the strongest dinosaurs in the game by some players.
