Scutellastra optima
Scutellastra optima is a species of true limpet, a marine gastropod mollusk in the family Patellidae.
Description
The shell of the holotype measures.The shell is large, solid, and ovate in shape, with a distinctly depressed profile. Its sculpture consists of numerous low radial riblets, which are approximately equal in width to the intervals between them. These riblets are layered over a coarser underlying structure of about a dozen low, broad radial elevations.
The color is striking: the depressed spaces between the primary elevations are a dull, deep maroon, while the smaller intervals between the riblets on the raised portions exhibit a diluted shade of the same hue. The interior is white, featuring a central field clouded with cinnamon tones.
