Pecten (bivalve)
''Pecten'' is a genus of large scallops or saltwater clams, Marine (ocean), marine bivalve molluscs in the family (biology), family Pectinidae, the scallops. This is the type genus of the family. Etymology The name ''Pecten'' is from the Latin word for a comb or Rake (tool), rake. Since 1904, a ''Pecten'' shell has been used as the basis of the logo of Royal Dutch Shell, Shell energy company. Species Species in the genus ''Pecten'' include: *''Pecten albicans, P. albicans'' (Schröter, 1802) *''Pecten afribenedictus, P. afribenedictus'' Kilburn & Dijkstra 1995 *''Pecten alcesianus, P. alcesianus'' † McLearn 1933 *''Pecten alpha, P. alpha'' † Dall 1898 *''Pecten argillensis, P. argillensis'' † Conrad 1860 *''Pecten assinboiensis, P. assinboiensis'' † Russell & Landes 1937 *''Pecten aurantiacus, P. aurantiacus'' Roding 1798 *''Pecten aztecus, P. aztecus'' † Bose 1906 *''Pecten barretti, P. barretti'' † Seeley 1861 *''Pecten bifidus, P. bifidus'' † Menke 1843 *''P ...

Marine (ocean)
The ocean is the body of salt water that covers approximately 70.8% of Earth. The ocean is conventionally divided into large bodies of water, which are also referred to as ''oceans'' (the Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic Ocean),"Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, https://www.merriam-webster.com/dictionary/ocean .

Bivalve
Bivalvia () or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class (biology), class of aquatic animal, aquatic molluscs (marine and freshwater) that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-bivalve shell, shells known as valve (mollusc), valves. As a group, bivalves have no head and lack some typical molluscan organs such as the radula and the odontophore. Their gills have evolved into ctenidium (mollusc), ctenidia, specialised organs for feeding and breathing. Common bivalves include clams, oysters, Cockle (bivalve), cockles, mussels, scallops, and numerous other family (biology), families that live in saltwater, as well as a number of families that live in freshwater. Majority of the class are benthic filter feeders that bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusk
Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater and even terrestrial species. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known extant i ...

Pectinidae
Scallop () is a common name that encompasses various species of Marine (ocean), marine bivalve mollusc, molluscs in the Taxonomy (biology), taxonomic Family (biology), family Pectinidae, the scallops. However, the common name "scallop" is also sometimes applied to species in other closely related families within the superfamily Pectinoidea, which also includes the thorny oysters. Scallops are a Cosmopolitan distribution, cosmopolitan family of bivalves found in all of the world's oceans, although never in fresh water. They are one of the very few groups of bivalves to be primarily "free-living", with many species capable of rapidly swimming short distances and even migrating some distance across the ocean floor. A small minority of scallop species live cemented to rocky substrate (biology), substrates as adults, while others attach themselves to stationary or rooted objects such as seagrass at some point in their lives by means of a filament they secrete called a byssal thread. ...
