Gastropoda

(Class)

Overview

[ Back to top ]

Class of molluscs including the winkles and whelks, sea slugs, water snails and land snails and slugs. Characterised by a large flat muscular foot on which they crawl about, and where a shell is present, it is a rounded or conical spirally coiled shell in one piece.

No shell, or have a single shell which is curved into a spiral, a pyramid, or ear-shaped (in our area). Crawl on muscular creeping foot.

Gastropod shell is important both as cover for motile (free-living) organisms, and attachment substrate for sessile (attached) organisms. Many invertebrates, including hermit crabs, polychaetes, slipper shells, tunicates, hydroids, bryozoans, sponges, and anemones commonly live in and on gastropod shell. Gastropod egg cases are also commonly laid on gastropod shell.
