What is a tuatara's body covering?

The tuatara's body is covered in rough, scaly skin made up of overlapping scales, which are somewhat similar to those of lizards. These scales are typically a mix of green, brown, and gray hues, helping the tuatara blend into its natural environment. Unlike lizards, tuataras have a unique arrangement of scales and skin features, including a distinctive row of spines along their back. This body covering helps protect them from predators and environmental conditions.
