mollusks The name mollusk comes from a Latin word meaning “soft.” On the outside, many mollusks appear anything but soft because they have hard shells. Inside, however, is a soft body. Thick tissue called the mantle covers the body. Glands in the mantle produce the shell. Read more about mollusks.
Mollusca, the scientific name applied since then means "soft animals", molluscs lacking any form of skeleton (mollis means soft in Latin). The field of science, though, dealing with molluscs, is malacology (malakos meaning soft in Greek).
Most mollusks have an open circulatory system with a heart that circulates the hemolymph in open spaces around the organs. The fishes didn't get called tangs because of their strong flavor, though. Most pairs of corresponding ganglia on both sides of the body are linked by commissures relatively large bundles of nerves. Over the following years, spat spread out sporadically and populated adjacent areas. National Council for Science and the Environment.

Word History Snails, conchs, whelks, and many other similar animals with shells are all called gastropods by scientists. The word gastropod comes from Greek and means "stomach foot," a name that owes its existence to the unusual anatomy of snails. While they don't have feet like ours, exactly, snails have a broad flat "foot" used for support and for forward movement. This foot runs along the underside of the animal—essentially along its belly.

Predation on bivalve mollusks by gastropod mollusks is common in coastal regions; however, few studies have examined whether predatory gastropod mollusks exhibit prey selection. First-stage larvae must penetrate and develop to the third infective stage in the terrestrial gastropod intermediate host in which the rate of larval development is determined by ambient temperatures. The infection route remains unclear with the apparent absence from Germany, Portugal, and Switzerland of the first intermediate host of C faba, the aquatic gastropod Bythinella austriaca, implying that other organisms might be involved in the parasite's life cycle.

Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters are in the superfamily Ostreoidea. Some types of oysters are commonly consumed cooked or raw, and in some locales are regarded as a delicacy. Some types of pearl oysters are harvested for the pearl produced within the mantle. Windowpane oysters are harvested for their translucent shells, which are used to make various kinds of decorative objects. The word oyster comes from Old French oistre , and first appeared in English during the 14th century. True oysters are members of the family Ostreidae. This family includes the edible oysters, which mainly belong to the genera Ostrea , Crassostrea , Ostreola , Magallana , and Saccostrea. Examples include the European flat oyster , eastern oyster , Olympia oyster , Pacific oyster , and the Sydney rock oyster. Ostreidae evolved in the Early Triassic epoch : The genus Liostrea grew on the shells of living ammonoids. Almost all shell-bearing mollusks can secrete pearls, yet most are not very valuable. Pearls can form in both saltwater and freshwater environments. Pearl oysters are not closely related to true oysters, being members of a distinct family, the feathered oysters Pteriidae. Both cultured pearls and natural pearls can be extracted from pearl oysters, though other molluscs, such as the freshwater mussels , also yield pearls of commercial value. The largest pearl-bearing oyster is the marine Pinctada maxima , which is roughly the size of a dinner plate. Not all individual oysters produce pearls naturally. In nature, pearl oysters produce pearls by covering a minute invasive object with nacre. Over the years, the irritating object is covered with enough layers of nacre to become a pearl. The many different types, colours and shapes of pearls depend on the natural pigment of the nacre, and the shape of the original irritant. Pearl farmers can culture a pearl by placing a nucleus, usually a piece of polished mussel shell, inside the oyster. In three to seven years, the oyster can produce a perfect pearl. Since the beginning of the 20th century, when several researchers discovered how to produce artificial pearls, the cultured pearl market has far outgrown the natural pearl market. A number of bivalve molluscs other than true oysters and pearl oysters also have common names that include the word "oyster", usually because they either taste like or look somewhat like true oysters, or because they yield noticeable pearls. Examples include:. In the Philippines, a local thorny oyster species known as Tikod amo is a favorite seafood source in the southern part of the country. Oysters are filter feeders , drawing water in over their gills through the beating of cilia. Suspended plankton and particles are trapped in the mucus of a gill, and from there are transported to the mouth, where they are eaten, digested, and expelled as feces or pseudofeces. Chesapeake Bay 's once-flourishing oyster population historically filtered excess nutrients from the estuary's entire water volume every three to four days. Today, it would take nearly a year. Oyster filtration can mitigate these pollutants. In addition to their gills, oysters can also exchange gases across their mantles, which are lined with many small, thin-walled blood vessels. A small, three-chambered heart , lying under the adductor muscle , pumps colorless blood to all parts of the body. At the same time, two kidneys , located on the underside of the muscle, remove waste products from the blood. Their nervous system includes two pairs of nerve cords and three pairs of ganglia. While some oysters have two sexes European oyster and Olympia oyster , their reproductive organs contain both eggs and sperm. Because of this, it is technically possible for an oyster to fertilize its own eggs. The gonads surround the digestive organs, and are made up of sex cells, branching tubules, and connective tissue. Once the female is fertilized, she discharges millions of eggs into the water. The larvae develop in about six hours and exist suspended in the water column as veliger larvae for two to three weeks before settling on a bed and maturing to sexual adulthood within a year. A group of oysters is commonly called a bed or oyster reef. As a keystone species , oysters provide habitat for many marine species. Crassostrea and Saccostrea live mainly in the intertidal zone , while Ostrea is subtidal. The hard surfaces of oyster shells and the nooks between the shells provide places where a host of small animals can live. Hundreds of animals, such as sea anemones , barnacles , and hooked mussels , inhabit oyster reefs. Many of these animals are prey to larger animals, including fish, such as striped bass , black drum and croakers. An oyster reef can increase the surface area of a flat bottom fold. An oyster's mature shape often depends on the type of bottom to which it is originally attached, but it always orients itself with its outer, flared shell tilted upward. One valve is cupped and the other is flat. Oysters usually reach maturity in one year. They are protandric ; during their first year, they spawn as males by releasing sperm into the water. As they grow over the next two or three years and develop greater energy reserves, they spawn as females by releasing eggs. Bay oysters usually spawn from the end of June until mid-August. An increase in water temperature prompts a few oysters to spawn. This triggers spawning in the rest, clouding the water with millions of eggs and sperm.
