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 of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Augustin Guillaume Bosc
Louis Augustin Guillaume Bosc (or Louis-Augustin Bosc d'Antic) (29 January 1759 – 10 July 1828) was a French botanist, invertebrate zoologist, and entomologist. Biography Bosc was born in Paris, the son of Paul Bosc d’Antic, a medical doctor and chemist. He studied at Dijon, where he was the pupil of botanist Jean-François Durande and chemist Louis-Bernard Guyton-Morveau. Being unable to become an artilleryman, he worked initially for the office of the controller general and then for the comptroller of the postal service. In time he took courses in botany under Antoine-Laurent de Jussieu and met botanist René Desfontaines and naturalist Pierre Marie Auguste Broussonet. He also took up with Jean Marie Roland and Madame Roland and formed a lasting relationship with Danish entomologist Johan Christian Fabricius. While working for the postal service he carried out work on natural history, publishing a description of a new species of fly, Orthezia characais, and a method of pr ...

Zoea
Crustaceans may pass through a number of larval and immature stages between hatching from their eggs and reaching their adult form. Each of the stages is separated by a moult, in which the hard exoskeleton is shed to allow the animal to grow. The larvae of crustaceans often bear little resemblance to the adult, and there are still cases where it is not known what larvae will grow into what adults. This is especially true of crustaceans which live as benthic adults (on the sea bed), more-so than where the larvae are planktonic, and thereby easily caught. Many crustacean larvae were not immediately recognised as larvae when they were discovered, and were described as new genera and species. The names of these genera have become generalised to cover specific larval stages across wide groups of crustaceans, such as ''zoea'' and ''nauplius''. Other terms described forms which are only found in particular groups, such as the ''glaucothoe'' of hermit crabs, or the ''phyllosoma'' of slippe ...

Neverita Duplicata
''Neverita duplicata'', common name the shark eye, is a species of predatory sea snail, a marine gastropod mollusk in the family Naticidae, the moon snails. In 2006, a paper was published which made it clear that a second, very similar, species with a smaller range of distribution also lives in part of the range inhabited by ''Neverita duplicata''. The second species had previously been considered to be simply a form of ''N. duplicata'', but it is now recognized as ''Neverita delessertiana''.Huelsken, T. ''et al.''

Knobbed Whelk
The knobbed whelk (''Busycon carica'') is a species of very large predatory sea snail, or in the US, a whelk, a marine gastropod mollusk in the family Busyconidae, the busycon whelks. The knobbed whelk is the second largest species of busycon whelk, ranging in size up to 12 in (305 mm). It is the only species in the genus Busycon. Distribution Knobbed whelks are native to the North Atlantic coast of North America from Cape Cod, Massachusetts to northern Florida. This species is common along the Georgia coast. It is the state shell of New Jersey and Georgia. Shell description The shell of most knobbed whelks is dextral, meaning that it is right-handed. If the shell is held in front of the viewer, with the spiral end up and the opening facing the viewer, the opening will be on the animal's right side. The shell is thick and strong and has six clockwise coils. The surface is sculpted with fine striations and there is a ring of knob-like projections protruding ...

Lightning Whelk
''Sinistrofulgur perversum'', the lightning whelk, is an edible 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.

Conch
Conch () is a common name of a number of different medium-to-large-sized sea snails. Conch shells typically have a high spire and a noticeable siphonal canal (in other words, the shell comes to a noticeable point at both ends). In North America, a conch is often identified as a queen conch, indigenous to the waters of the Gulf of Mexico and Caribbean. Queen conches are valued for seafood and are also used as fish bait. The group of conches that are sometimes referred to as "true conches" are marine gastropod molluscs in the family Strombidae, specifically in the genus ''Strombus'' and other closely related genera. For example, ''Lobatus gigas'', the queen conch, and ''Laevistrombus canarium'', the dog conch, are true conches. Many other species are also often called "conch", but are not at all closely related to the family Strombidae, including ''Melongena'' species (family Melongenidae) and the horse conch ''Triplofusus papillosus'' (family Fasciolariidae).

Whelk
Whelk (also known as scungilli) is a common name applied to various kinds of sea snail. Although a number of whelks are relatively large and are in the family Buccinidae (the true whelks), the word ''whelk'' is also applied to some other marine gastropod species within several families of sea snails that are not very closely related. Many have historically been used, or are still used, by humans and other animals as food. In a reference serving of whelk, there are of food energy, 24 g of protein, 0.34 g of fat, and 8 g of carbohydrates. Dogwinkles, a predatory species, were used in antiquity to make a rich red dye that improves in color as it ages. True whelks are carnivorous, and feed on annelids, crustaceans, mussels and other molluscs, drilling holes through shells to gain access to the soft tissues. Whelks use chemoreceptors to locate their prey. Usage The common name "whelk" is also spelled ''welk'' or even ''wilk''. The species, genera and families re ...

Clibanarius Vittatus-dorsal
''Clibanarius'' is a genus of hermit crabs in the family Diogenidae. Like other hermit crabs, their abdomen is soft-shelled and sheltered in a gastropod shell. Typically marine like all their relatives, the genus includes '' C. fonticola'', the only known hermit crab species that spends all its life in freshwater. The feeding rates of ''Clibanarius spp.'' change with temperature which, given their broad distributions, may have considerable consequences for the stability reef systems as sea temperatures rise in the future. They are omnivores, but mostly prey on small animals and scavenge carrion. Species As of 2009, about sixty species are recognized in ''Clibanarius''; new species are discovered and described occasionally. Others have been placed here at one time or another but are now assigned to other genera of Diogenidae, namely '' Bathynarius, Calcinus, Paguristes, Strigopagurus'' and '' Trizopagurus''. The ''Clibanarius'' species are: *'' Clibanarius aequabilis'' (Dana, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predation
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and inv ...
