A parasaurolophus is a relatively gentle creature that prefers to wallow in swamplands. They feed on all forms of vegetation that grow in such areas, using their duckbill-shaped jaws to scoop up mouthfuls of algae and swamp plants. Their crests are complex sounding chambers that allow them to generate shockingly loud and haunting, almost mournful cries that can carry for miles. Their skin is capable of changing through a wide variety of colors and shades. During mating season, these dinosaurs can put on a veritable symphony of sound and color as they try to attract mates.

A parasaurolophus is usually about 35 feet long.
