Leodia Sexiesperforata
''Leodia sexiesperforata'', commonly known as the six-holed keyhole urchin, is a species of sand dollar, in the echinoderm order Clypeasteroida. It is native to tropical and sub-tropical parts of the western Atlantic Ocean where it buries itself in soft sediment in shallow seas. Description Like other sand dollars, ''Leodia sexiesperforata'' is radially symmetrical and flattened dorso-ventrally, having a circular or semi-pentagonal shape, but it also displays secondary, front-to-back bilateral symmetry. It is usually somewhere between in diameter. The mouth is on the oral (under) surface and is surrounded by the peristome and five deep, narrow food grooves, that branch as they near the margin. On the aboral (upper) surface of the test are five short, petal-like areas which are used as gills and six oval lunules (slots) which give the species its name "sexiesperforata". Five of these slots are in the ambulacral areas and the sixth is on the posterior interambulacral area. The a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sand Dollar
Sand dollars (also known as sea cookies or snapper biscuits in New Zealand and Brazil, or pansy shells in South Africa) are species of flat, burrowing sea urchins belonging to the order Clypeasteroida. Some species within the order, not quite as flat, are known as sea biscuits. Sand dollars can also be called "sand cakes" or "cake urchins". Names The term "sand dollar" derives from the appearance of the tests (skeletons) of dead individuals after being washed ashore. The test lacks its velvet-like skin of spines and has often been bleached white by sunlight. To beachcombers of the past, this suggested a large, silver coin, such as the old Spanish dollar, which had a diameter of 38–40 mm. Other names for the sand dollar include ''sand cakes, pansy shells, snapper biscuits, cake urchins'', and ''sea cookies''. In South Africa, they are known as ''pansy shells'' from their suggestion of a five-petaled garden flower. The ''inflated sea biscuit'' or Caribbean sand dollar, ' ...

Mellita
Keyhole sand dollar refers to five living species of sand dollars in the genus ''Mellita'', plus the extinct †'' Mellita aclinensis''. They are found on the Atlantic coasts of the Americas, ranging across the Caribbean Islands (e.g. Bermuda, Jamaica and Puerto Rico), from the southern United States at the north, to the southeastern coast of Brazil at the south. Their range includes the Pacific coast of equatorial countries, such Central American countries and near, in the north sporadically across the Pacific coast of Mexico. Description The velvet-like skin of live keyhole sand dollars is usually tan, brown, grey or dark green in colour. Like all sand dollars, they are found in shallow seawater below tide lines, where they burrow into the seabed to obtain food. The creatures feed on fine particles of plankton and other organic matter they filter from the water. Keyhole sand dollars are so named because of the distinctive keyhole-shaped perforation toward the rear of the end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive catalogue and list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as th ...
