|Five views of a shell of Haliotis midae|
- Haliotis midae volcanius Patamakanthin & Eng, 2007
The size of the shell varies between 12 and 20 cm (4.7–7.9 in). "The large shell has a rounded-oval shape and is moderately convex. The distance of the apex from the margin about equals one-fifth the greatest length of the shell. The body whorl is strongly angled at the position of the perforations, perpendicularly descending from the angle to the columellar margin. The surface shows strong, elevated, radiating wrinkles or lamellae, but no spiral markings when adult. The 6 to 11 perforations are small, subcircular, and separated by spaces greater than their own diameter. The two sides are about equally curved. The convexity varies with age. The color of the shell is yellowish-gray. The folds are usually stained with coral-red. The surface is dull, with fine oblique growth-wrinkles and coarse, prominent, less oblique elevated and wavy radiating lamellae. The low spire is composed of about 3 whorls. The body whorl is angulated at the row of perforations. The inner surface is pearly, many-colored, red predominating in young specimens. The muscle-scar is large, rounded, very rough, especially in old shells, which often have coppery stains inside. The columellar plate is rather broad (one-seventh to one-tenth the width of the shell), sloping inward. Its face is a little concave and not at all truncated at the base. The cavity of the spire is large, showing about 1½ whorls from below."
