Common term for animals of the phylum Mollusca Includes groups such as the bivalves (mussels, oysters etc ), cephalopods (squid, octopus etc ) and gastropods (abalone, snails) Over 80,000 species in total with fossils back to the Cambrian period
a group of soft-bodied animals, most of which live in water and have shells, such as clams, oysters and mussels; snails and slugs are common land living molluscs
A group of invertebrates with soft bodies that occur in marine and freshwater and on land They breath using gills and many species have protective shells
Invertebrates, with a fleshy soft body and, usually, a hard shell May be marine, freshwater or terrestrial; includes gastropods (snails, limpets), bivalves (oysters, mussels) cephalopods, etc
mol·lusc molluscs in AM, use mollusk A mollusc is an animal such as a snail, clam, or octopus which has a soft body. Many types of mollusc have hard shells to protect them
A member of a varied group of invertebrates that secrete calcium carbonate to form shells The shells may be external and obvious (as in snails and mussels) or internal and small (as in slugs)
An invertebrate animal lacking an external skeleton, but possessing an external shell lined with a specialized epidermal membrane called the mantle (much reduced in some species, such as the squids)
common name for members of a phylum (sub-section of the animal kingdom) of soft-bodied animals, with bodies usually covered by a hard external shell Some molluscs, like the octopus, do not possess a shell
An aquatic, soft-bodies invertebrate that lives in a shell, found either in seawater or freshwater If it has only one shell (e g the abalone shell), it is univalve If it has two shells connected by a hinge, it is an oyster or bivalve mollusc
A group of freshwater and saltwater animals with no skeleton and usually one or two hard shells made of calcium carbonate Includes the oyster, clam, mussel, snail, conch, scallop, squid, and octopus
Soft-bodied marine and freshwater animals that often secrete some kind of protective shell Members of this group include: clams, snails, octopus and squid
or mollusc Any of some 75,000 species of soft-bodied invertebrate animals (phylum Mollusca), many of which are wholly or partly enclosed in a calcium carbonate shell secreted by the mantle, a soft covering formed from the body wall. Between the mantle and the body is the mantle cavity. Mollusks occur in most habitats from the deep sea to high mountains. Living mollusks are usually grouped into eight classes: Gastropoda (see gastropod), Bivalvia or Pelecypoda (see bivalve), Cephalopoda (see cephalopod), Scaphopoda (tusk shells), Aplacophora (Solenogasters), Caudofoveata (sometimes included in the Aplacophora order), Polyplacophora (chitons), and Monoplacophora. Mollusks are economically important as food, and their shells are widely used in jewelry and decorative items
an invertebrate (a class of organisms have no spine or backbone) having a soft unsegmented body usually enclosed in a shell (clams, snails, and octopuses are examples)
– Member of the phylum Mollusca Invertebrate animals with soft unsegmented bodies, a muscular foot, and a body enclosed in a mantle Most mollusks have a calcareous outer shell
