Taxonomy
''Scutellastra aphanes'' was originally described by Gary Robson in 1986, as ''Patella aphanes''. The specific name "aphanes" means "unseen" or "unnoticed" in Greek.
The species and other Southern African ''Patella'' were later moved to ''Scutellastra'' in 1998 based on morphological analysis.
Description
''Scutellastra aphanes'' consists of two distinct ecomorphs, one associated with beds of the mussel
Perna perna and the other on nearby rocks. The most striking difference between the two is that the rock-dwelling form possesses more prominent shell ribs and the ventral margin is not concave in profile, unlike the mussel-dwelling form.
