Scutellastra argenvillei or Argenville's limpet, is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets. [1]

Contents

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]

The Marine biodiversity of South Africa is the variety of living organisms that live in the seas off the coast of South Africa. It includes genetic, species and ecosystems biodiversity in a range of habitats spread over a range of ecologically varied regions, influenced by the geomorphology of the seabed and circulation of major and local water masses, which distribute both living organisms and nutrients in complex and time-variable patterns.
