Wide spiral ridge running around the shell between the row of holes and the spire. This ridge is best seen on the inside of the shell, where it forms an obvious groove. The internal groove of animals east of central South Australia is not as sharply cornered as in western animals, and the eastern animals were called H. emmae until recently. Haliotis scalaris resembles H. rubra, but is a smaller animal and has a wide groove around the outside of the shell next to the row of holes.
