Louis Charles Kiener
Louis Charles Kiener (31 July 1799 – 24 July 1881) was a French malacologist born in Paris. He was the author of the 12-volume ''Spécies général et iconographie des coquilles vivantes comprenant la collection du Muséum d'histoire naturelle de Paris, la collection Lamarck, celle du prince Masséna (appartenant maintenant a M.B. Delessert) et les découvertes récentes des voyageurs'', translated into English as "General species and iconography of recent shells : comprising the Massena Museum, the collection of Lamarck, the collection of the Muséum national d'histoire naturelle, Museum of Natural History, and the recent discoveries of travellers.

Operculum (gastropod)
An operculum (; ) is a corneous or calcareous anatomical structure like a trapdoor that exists in many (but not all) groups of sea snails and freshwater snails, and also in a few groups of land snails, including the Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc. The operculum is attached to the upper surface of the foot and in its most complete state, it serves as a sort of "trapdoor" to close the aperture (mollusc), aperture of the shell when the soft parts of the animal are retracted. The shape of the operculum varies greatly from one family of gastropods to another. It is fairly often circular, or more or less oval in shape. In species where the operculum fits snugly, its outline corresponds exactly to the shape of the aperture (mollusc), aperture of the shell and it serves to seal the entrance of the shell. Many families have opercula that are reduced in size, and which are not capable of closing the shell aperture. Opercula have sometimes been modifie ...

Cannibalism (zoology)
Cannibalism is the act of consuming another individual of the same species as food. Cannibalism is a common ecological interaction in the animal kingdom and has been recorded in more than 1,500 species. Human cannibalism is also well documented, both in ancient and in recent times. The rate of cannibalism increases in nutritionally poor environments as individuals turn to members of their own species as an additional food source.Elgar, M.A. & Crespi, B.J. (1992) ''Cannibalism: ecology and evolution among diverse taxa'', Oxford University Press, Oxford ngland New York. Cannibalism regulates population numbers, whereby resources such as food, shelter and territory become more readily available with the decrease of potential competition. Although it may benefit the individual, it has been shown that the presence of cannibalism decreases the expected survival rate of the whole population and increases the risk of consuming a relative. Other negative effects may include the increa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clibanarius Vittatus
The thinstripe hermit crab, ''Clibanarius vittatus'', is a species of hermit crab in the family Diogenidae. It is found in the Caribbean Sea, the Gulf of Mexico and the western Atlantic Ocean. Description Like other hermit crabs, ''Clibanarius vittatus'' lives inside the empty shell of a gastropod mollusc. This protects its soft abdomen and normally only its head and limbs project through the aperture of the shell. The chelipeds (claw-bearing legs) and claws of ''Clibanarius vittatus'' are small, both the same size, and covered in short bristles. When threatened, the animal retreats into the shell and the chelipeds block the aperture. The outside of the claws bear small blue tubercles. The body and legs are dark green or brown; the body is faintly streaked with white and the legs have more distinct white or grey stripes. Adult crabs often occupy shells of over in length. Distribution and habitat ''Clibanarius vittatus'' is found in shallow parts of the Caribbean Sea, the Gulf o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atrina
''Atrina'' is a cosmopolitan genus of bivalve molluscs belonging to the family Pinnidae. A typical species is ''Atrina fragilis, A. fragilis'', found in British waters. ''Atrina rigida, A. rigida'' (John Lightfoot FRS, Lightfoot, 1786) is found on the southeast coast of North America and in the West Indies. The type species is ''A. nigra'' (Lewis Weston Dillwyn, Dillwyn, 1817, originally ''P. nigra''). ''Atrina'' is considered to represent the more primitive form within the Pinnidae; however, both genera ''Pinna (bivalve), Pinna'' and ''Atrina'' are very ancient. The genus ''Atrina'' is represented within the fossil record from the Triassic period to the Quaternary period (age range: 242.0 to 0.0 million years ago). These fossils have been found all over the world. Description Molluscs within this genus are characterized by elongated, wedge-shaped shells, distinguished from the genus ''Pinna (genus), Pinna'' by the lack of any grooves in the nacreous lining of the shell, and by ...

Bivalves
Bivalvia () or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of aquatic molluscs (marine and freshwater) that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-shells known as 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 ctenidia, specialised organs for feeding and breathing. Common bivalves include clams, oysters, cockles, mussels, scallops, and numerous other 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 hard surfaces. Some bivalves, such as scallops and file shells, can swim. Shipworms bore into wood, clay, or ston ...

Murex
''Murex'' is a genus of medium to large sized predatory tropical sea snails. These are carnivorous marine gastropod molluscs in the family Muricidae, commonly called "murexes" or "rock snails".Houart, R.; Gofas, S. (2010). Murex Linnaeus, 1758.

Lobatus Gigas
''Aliger gigas'', originally known as ''Strombus gigas'' or more recently as ''Lobatus gigas'', commonly known as the queen conch, is a species of large sea snail, a marine gastropod mollusc in the family of true conches, the Strombidae. This species is one of the largest molluscs native to the Caribbean Sea, and tropical northwestern Atlantic, reaching up to in shell length. ''A. gigas'' is closely related to the goliath conch, ''Titanostrombus goliath'', a species endemic to Brazil, as well as the rooster conch, ''Aliger gallus''. The queen conch is herbivorous. It feeds by browsing for plant and algal material growing in the seagrass beds, and scavenging for decaying plant matter. These large sea snails typically reside in seagrass beds, which are sandy plains covered in swaying sea grass and associated with coral reefs, although the exact habitat of this species varies according to developmental age. The adult animal has a very large, solid and heavy shell, with knob- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinistrofulgur Perversum
''Sinistrofulgur perversum'', the lightning whelk, is a species of very large predatory sea snail or whelk, a marine gastropod mollusc in the family Busyconidae, the busycon whelks. This species has a left-handed or sinistral shell. It eats mostly bivalves. There has been some disagreement about the correct scientific name for this species, which has been confused with '' Sinistrofulgur sinistrum'' Hollister, 1958, and ''Busycon contrarium'' (Conrad, 1840), which is an exclusively fossil species.J.

Predator
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common List of feeding behaviours, feeding behaviours that includes parasitism and micropredation (which usually do not kill the Host (biology), host) and parasitoidism (which always does, eventually). It is distinct from Scavenger, scavenging on dead prey, though many predators also scavenge; it overlaps with Herbivore, herbivory, as Seed predation, seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategy, hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predation, ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry.
