Scutellastra kermadecensis is a species of true limpet, a marine gastropod mollusk in the family Patellidae. [1] It is endemic to the Kermadec Islands (New Zealand). [3]
Original species description: [2]
The large and massive shell is conical with the apex subcentral. The slopes of the cone are nearly straight. The outline is short ovate, slightly narrower in front. The exterior is whitish, apparently strongly ribbed when perfect, but the specimens described are everywhere deeply eroded. The border is lightly scalloped by the ribbing, and finely puckered at the edge. Muscle-scar roughened, strongly marked, and either white or bright orange. The rest of the interior is white, stained in places with livid-brown or purplish. Length 135, breadth 115, alt. 48 mm.
Scutellastra kermadecensis commonly reaches shell lengths exceeding 135 mm (5.3 in). [3]
Scutellastra kermadecensis is a broadcast spawner with pelagic larvae. It is a protandrous sequential hermaphrodite. [3]
This marine species is endemic to the waters off the Kermadec Islands. It is the dominant grazing invertebrate between the low intertidal and shallow subtidal zones. It can reach densities in excess of 40 individuals per square meter. [3]
Despite the relatively small distribution area, there is evidence for small but significant genetic differentiation between populations sampled in the middle and northern parts of the island chain. [3]
Patellidae is a taxonomic family of true limpets, marine gastropod molluscs in the superfamily Patelloidea. (The superfamily Patelloidea should not be confused with the similar-sounding genus of true limpets Patelloida which is in the family Lottiidae within the superfamily Lottioidea, also part of the Patellogastropoda.)
Cellana is a genus of sea snails or limpets, marine gastropod molluscs in the family Nacellidae, the true limpets.
Patella vulgata, common name the common limpet or common European limpet is a species of sea snail. It is a typical true limpet; a marine gastropod mollusc in the family Patellidae, with gills. This species occurs in the waters of Western Europe.
Patella is a genus of sea snails with gills, typical true limpets, marine gastropod mollusks in the family Patellidae, the true limpets.
Cymbula adansonii is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae. It is one of the several families of true limpets. Marine gastropods, colloquially classified as snails and slugs, encompass the entire class of invertebrates in the Mollusca phylum. True limpets, are pelagic snails within the Patellidae family.
Helcion concolor, common name the variable 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.
Patella ferruginea, commonly known as the ferruginous limpet is a species of true limpet, a marine gastropod mollusk in the family Patellidae. It is a large limpet, endemic to the western Mediterranean Sea, and although common in the past, it is now rare and restricted to only a few locations.
Patella lugubris is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets.
Scutellastra natalensis is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets.
Scutellastra aphanes is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets. It is endemic to South Africa.
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.

Bathymophila dawsoni is a species of sea snail, a marine gastropod mollusk in the family Solariellidae.
Cymbula sanguinans, the giant pinkray limpet, is a species of giant limpet, a marine mollusc in the family Patellidae. It is native to the coast of South Africa. At one time thought to be a subspecies of Cymbula miniata, molecular analysis has shown C. sanguinans warrants being treated as a full species, despite there being no obvious morphological differences between the two. This makes difficult the task of deciding which of the previous research studies refer to C. sanguinans, and which refer to C. miniata.
