is any invertebrate having a soft body often protected by a shell. Includes the snail, bivalve (mollusc, clam, mussel), squid, and octopus.
(mol'-lusc) A solitary invertebrate belonging to the phylum Mollusca, characterized by a nonsegmented body that is bilaterally symmetrical, and by a radially or biradially symmetrical mantle and shell. Among the classes included in the molluscs are the gastropods (snails), bivalves (pelecypods), and cephalopods (squid, nautiluses, ammonites, and octopi).
have you ever looked closely at one of these suckers and noticed that they have little hairs at the edge of their shells
group of animals that includes land snails and slugs, as well as marine animals such as mussels, oysters, snails and seaslugs.
moll-usk Any invertebrate of the phylum Mollusca, with a soft body and usu. a hard shell, including limpets, snails, cuttlefish, oysters, mussels, etc.
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).
invertebrate having a soft unsegmented body usually enclosed in a shell
Animal without a backbone but with an exterior shell or an interior hard part for body support, eg slug and snail on land and clam, mussel, squid and octopus at sea.
n. Any soft-bodied invertebrate of the phylum Mollusca, usually wholly or partly enclosed in a calcium-carbonate shell secreted by a soft mantle covering the body, and often possessing a single foot and a radula.
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.
Soft-bodied organisms that usually have a hard shell that may be external and obvious for example snails (gastropods) and mussels (bivalves), or internal and small for example squids (cephalopods).
A soft-bodied animal with a hard shell.
phylum of invertebrates which include modern creatures such as snails, slugs, cockles, and squids. Molluscs have a muscular 'foot' for digging, movement, or swimming. Many have a hard protective shell. Some forms such as most slugs and octopuses have lost their shells as they have developed other ways of protecting themselves. Molluscs are common fossils found in rocks from the Cambrian period onwards, and are especially common in the Mesozoic and Cenozoic. (See Geological Timescale).
(or mollusk) (mol - usk) A marine invertebrate that creates and lives in a calcareous shell. Clams, snails, oysters, and whelks are all mollusks.
An invertebrate with a soft body often protected by a shell such as clam, oyster and mussel.
A large group of creatures including slugs, snails, mussels and limpets.
Soft-bodied, hard shelled animal. Also known as shellfish. (eg. Oyster, abalone and Mussel)
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.
