Phylum Mollusca: several classes, in particular Gastropoda, Bivalvia, and Cephalopoda
Example sentencesExamples

- As gardeners already know, all other slugs and snails (or gastropod mollusks, to the experts) sport a soft and slimy foot.

- Densely vegetated ditches with temporary standing water can be an important habitat for freshwater molluscs.
- Small fish and a variety of other aquatic creatures, including mollusks and crustaceans, make up the Pigeon Guillemot's diet.

Derivatives

molluscan

adjective məˈlʌskən

Despite their antiquity, living terebratulids are advanced organisms, able to out-perform molluscan bivalves in filter feeding efficiency under certain conditions.
Example sentencesExamples
- Four new molluscan species, a bivalve and three gastropods, are named from shallow-marine, lower Upper Cretaceous strata in Oregon.
- Chemicals, usually in the form of short-chain fatty acids, or specific amino acids, which are released from the molluscan host, then attract the free-swimming miracidia.
- Even if detailed studies of molluscan anatomy were forthcoming, the shell of molluscs would be of little use in cladistic analysis because of rampant convergence.
- The adaptations of gastropods for drilling molluscan prey also increased during the Mesozoic and Cenozoic.

molluscoid

molluscous

adjective məˈlʌskəs

Origin

Late 18th century: from modern Latin mollusca, neuter plural of Latin molluscus, from mollis 'soft'.

Most molluscs have hard shells, but they need these because they are so soft underneath, which gives them their name, from Latin mollis ‘soft’. This also lies behind mollify (Late Middle English) originally to make soft, emollient (mid 17th century), and share an Indo-European root with Germanic melt (Old English) and mild (Old English).
