It is endemic to the south and west coasts of Namibia and South Africa in southern Africa.[2]

Description

It is a large and relatively tall limpet, with an oval base, slightly narrower at one end, with a maximum size of about 90 mm. The outer surface has fine radiating ridges, and the apex is commonly eroded. Inner surface is generally white.[2]

Ecology

This limpet is abundant on moderately exposed shores in the low inter-tidal and shallow subtidal zone on the west coast of South Africa, but is being displaced by the invasive Mediterranean mussel Mytilus galloprovincialis. The lower inter-tidal zone in this area is also referred to as the Cochlear-Argenvillei zone.[3] It feeds on kelp by trapping the edge of fronds under the edge of its shell while feeding.[2]
