Fissurella afra is a species of keyhole limpet (marine gastropod mollusc) in the family Fissurellidae.[1]
Description
The shell of F. afra is ovate-oblong and convex with a moderately elevated, subcentral apex. The foramen (keyhole) is ovate and slightly constricted medially; the exterior shows fine radiating striae with darker violet-brown bands on a pale background, and the interior is typically whitish. Historic authors distinguished it from Diodora nimbosa by the more elevated summit and a foramen positioned further forward.[2][3][4]
Distribution
Fissurella afra is recorded from the Cape Verde Islands, including Santiago (São Tiago).[1] Additional taxonomic and occurrence metadata are aggregated by NOAA Copepedia.[5]
Taxonomy
The species was described by Quoy & Gaimard in 1834 during the voyage of the Astrolabe.[2] The name Fissurella de Praya has been treated as a synonym of F. afra in modern databases.[1]
