Nacella kerguelenensis is a southern, cold-water species of limpet, a marine gastropod mollusc in the family Nacellidae, the true limpets.
This true limpet is endemic to Australia's sub-Antarctic Macquarie, Heard, and McDonald islands, and France's Kerguélen Islands.
Limpets are a group of aquatic snails that exhibit a conical shell shape (patelliform) and a strong, muscular foot. Although all limpets are members of the class Gastropoda, limpets are polyphyletic, meaning the various groups which are referred to as "limpets" have descended independently from different ancestral gastropods. This general category of conical shell is known as "patelliform" (dish-shaped). All members of the large and ancient marine clade Patellogastropoda are limpets. Within that clade, the members of the Patellidae family in particular are often referred to as "true limpets".
Z Special Unit was a joint Allied special forces unit formed during the Second World War to operate behind Japanese lines in South East Asia. Predominantly Australian, Z Special Unit was a specialist reconnaissance and sabotage unit that included British, Dutch, New Zealand, Timorese and Indonesian members, predominantly operating on Borneo and the islands of the former Netherlands East Indies.
The Patellogastropoda, common name true limpets and historically called the Docoglossa, are members of a major phylogenetic group of marine gastropods, treated by experts either as a clade or as a taxonomic order.
Fissurellidae, common name the keyhole limpets and slit limpets, is a taxonomic family of limpet-like sea snails, marine gastropod molluscs in the clade Vetigastropoda. Their common name derives from the small hole in the apex of their cone-like shells. Although superficially resembling "true" limpets, they are in fact not closely related to them.
Nacella macquariensis is a species of true limpet, a marine gastropod mollusc in the family Nacellidae. It is found on the lower foreshore and in the shallow sub-littoral zone of certain islands in the southern Indian Ocean and Southern Ocean.
Patellidae is a taxonomic family of sea snails or true limpets, marine gastropod molluscs in the clade Patellogastropoda.
Cellana is a genus of sea snails or limpets, marine gastropod molluscs in the family Nacellidae, the true limpets.
Nacella is a southern, cold-water genus of true limpets, marine gastropod molluscs in the family Patellidae, the true limpets.
Patelloida is a genus of sea snails or true limpets, marine gastropod molluscs in the family Lottiidae, one of the families of true limpets.
Cellana sandwicensis, common name the yellow-foot ʻopihi, is a species of edible true limpet, a marine gastropod mollusc in the family Nacellidae, one of the families of true limpets.
Cellana exarata, common name the black-foot ʻopihi and Hawaiian blackfoot is a species of edible true limpet, a marine gastropod mollusc in the family Nacellidae, one of the families of true limpets.
Cellana talcosa, the talc limpet or turtle limpet is a species of true limpet, a marine gastropod mollusc in the family Nacellidae, which is one of the true limpet families.
Erginus rubellus is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Acmaeidae, one of the families of true limpets.
Lepeta caeca, common name the northern blind limpet, is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lepetidae, one of the families of true limpets.
Patella ferruginea, commonly known as the ribbed Mediterranean 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. It is a large limpet, native to the western Mediterranean Sea, and although common in the past, it is now rare and restricted to only a few locations.
Patella rustica, common name rustic 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.

Patelloida saccharina, common name the broad-ribbed limpet, is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae, one of the families of true limpets.
Limpet Island is the southernmost of the Léonie Islands, Antarctica, lying in the entrance to Ryder Bay, close off the southeast coast of Adelaide Island. The Léonie Islands were discovered and first roughly surveyed in 1909 by the Fourth French Antarctic Expedition under Jean-Baptiste Charcot. Limpet Island was surveyed in 1948 by the Falkland Islands Dependencies Survey and so named by them because of the large number of limpet shells found there.
Operation Scorpion was a proposed operation in World War Two by Australia's Z Special Unit.
