Brachiosaurus is a five-star large herbivore. No carnivores attack it purposely, presumably because it's too big to attack. Brachiosaurus is significantly tall, reaching the treetops even on all fours. It measures 25 meter (82 feet) in length. This Brachiosaur seemed to be a mix of the Jurassic Park III and Jurassic Park Brachiosaurus colors.
