Medusafissurella
''Medusafissurella'' is a genus of minute deepwater keyhole limpets, marine gastropod mollusks or micromollusks in the family Fissurellidae, the keyhole limpets and slit limpets.Bouchet, P.; Gofas, S. (2012). Medusafissurella McLean & Kilburn, 1986. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=536032 on 2013-01-17 Etymology In Greek mythology Medusa was a Gorgon, a monster with snakes for hair. The radiating tentacles in ''Medusafissuralla'' recall the serpentine locks of this monster. Description ''Medusafissurella'' is closely associated with ''Amblychilepas'' and '' Dendrofissurella'' with which it shares radular and shell characters. But ''Medusafissurella'' has a smaller body than the species in '' Amblychilepas'', the genus to which it was previously assigned. The body of species in ''Medusafissurella'' is larger than the shell. The anterior part of the shell is raised but is markedly narrowed. This characte ...

Medusafissurella Chemnitzii
Medusafissurella chemnitzii: An Overview Introduction Medusafissurella chemnitzii is a species of sea snail belonging to the family Fissurellidae, commonly known as keyhole limpets and slit limpets1. This marine gastropod mollusk is notable for its unique shell structure and ecological significance. Taxonomy and Classification * Domain: Eukaryota * Kingdom: Animalia * Phylum: Mollusca * Class: Gastropoda * Subclass: Vetigastropoda * Order: Lepetellida * Family: Fissurellidae * Subfamily: Fissurellinae * Genus: Medusafissurella * Species: M. chemnitzii The species was first described by G. B. Sowerby I in 18351. Morphology The shell of Medusafissurella chemnitzii can reach a length of up to 24.6 mm1. It is characterized by its keyhole or slit-like opening, which is a distinctive feature of the Fissurellidae family. The shell’s structure aids in respiration and excretion, allowing the snail to thrive in its marine environment. Distribution and Habitat This species is foun ...

Medusa
In Greek mythology, Medusa (; ), also called Gorgo () or the Gorgon, was one of the three Gorgons. Medusa is generally described as a woman with living snakes in place of hair; her appearance was so hideous that anyone who looked upon her was Petrifaction in mythology and fiction, turned to stone. Medusa and her Gorgon sisters Euryale and Stheno were usually described as daughters of Phorcys and Ceto; of the three, only Medusa was mortal. Medusa was beheaded by the Greek hero Perseus, who then used her head, which retained its ability to turn onlookers to stone, as a weapon until he gave it to the goddess Athena to place on her Aegis, shield. In classical antiquity, the image of the head of Medusa appeared in the apotropaic magic, evil-averting device known as the ''Gorgoneion''. According to Hesiod and Aeschylus, she lived and died on Sarpedon, somewhere near Cisthene (Mysia), Cisthene. The 2nd-century BC novelist Dionysios Skytobrachion puts her somewhere in Ancient Libya, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amblychilepas
''Amblychilepas'' is a genus of sea snails, marine gastropod mollusks in the family Fissurellidae, the keyhole limpets. Distribution The species from this genus can be found in temperate waters of Australia, except ''Amblychilepas platyactis'' that is found along the Atlantic coast of the Cape Peninsula, South Africa.

The body of species in this genus is larger than the shell. The anterior part of the oval shell is narrower than the rest. Both ends of the shell are somewhat raised. The sculpture of the shell shows fine radial ribs. The upper mantle fold only slightly envelops the edge of the shell. The apical opening (''foramen'') is elongate-oval and situated almost in the center. Long papillae extend from the mantle towards the foramen, as in ''A. nigrita''. The foot extends behind the shell with a length larger than the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fissurella
''Fissurella'' is a genus of small to medium-sized sea snails or limpets, marine (ocean), marine gastropod mollusks in the subfamily Fissurellinae of the family Fissurellidae, the keyhole limpets.Bouchet, P.; Gofas, S.; Rosenberg, G. (2012). Fissurella Bruguière, 1789. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138013 on 2013-01-14 Description The size of the body does not exceed or marginally exceeds that of the shell. The outer radular plate has four cusps. The propodium (= the anterior end of the foot) has no tentacles. Ecology Like all other fissurellids, ''Fissurella'' species are herbivores, using the radula to scrape up algae from the surface of rocks. Water for respiration and excretion is drawn in under the edge of the shell and exits through the "keyhole" at the apex. Species According to the World Register of Marine Species (WoRMS), the following species with accepted names are included within the ...

Fissurellidae
Fissurellidae, common name the keyhole limpets and slit limpets, is a taxonomic family of small to medium-sized limpet-like sea snails, marine gastropod molluscs in the clade Vetigastropoda.Rosenberg, G. (2012). Fissurellidae. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=111 on 2013-01-02 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. Distribution The distribution of fissurellids is worldwide, from cold waters to tropical waters. Powell A. W. B., ''New Zealand Mollusca'', William Collins Publishers Ltd, Auckland, New Zealand 1979 Habitat Fissurellids live in habitats on and under rocks in the lower intertidal zones to deeper waters.

George Brettingham Sowerby III
George Brettingham Sowerby III (London, 16 September 1843 – 31 January 1921) was a British conchologist, publisher, and illustrator. He was the eldest son of G. B. Sowerby II. At the age of seventeen or eighteen, he began his career as a conchologist, operating from his father's residence. From October 1897, the business was conducted under the name Sowerby and Fulton. Mr. Sowerby retired in January 1916. He married Miss Rose Wilkie in June 1867, and they had three children: one son and two daughters. He, too, worked (like his father George Brettingham Sowerby II and his grandfather George Brettingham Sowerby I) on the ''Thesaurus Conchyliorium'', a comprehensive, beautifully illustrated work on molluscs. He was colour blind, and thus his daughter did most of the colouring of his engravings. He was a prolific contributor to the scientific literature. He authored numerous papers for various societies and was responsible for the description of around 720 new species of mollus ...
