It is covered with a whorled cream-coloured shell. The head of this marine snail bears two antennae. The animal has a tube-shaped siphon. ReproductionMating takes place from about 6 months of age. Fertilization occurs internally. The female holds onto the sperm and fertilizes the eggs when they are spawned, a few weeks later. The eggs are laid in a clump, in capsules that each contain hundreds of fertilized eggs. DietThey mostly eat molluscs and dead fish that they find on the bottom. PredatorsTheir enemies are mainly fish and invertebrates, especially cod, haddock, other marine snails and sea stars. HabitatThese molluscs live in cold saltwater over a variety of bottoms. They young are mostly found in shallow tidal pools, while the adults are found at depths of up to 200 metres. Ecology, behaviourA waved whelk is able to detect its prey chemically, using its siphon. Once it has captured a victim, it grates its long, toothed tongue over its surface. These molluscs hide under the sand from their predators, leaving only their siphons exposed in order to breathe in water and oxygenate their gills. These marine snails interfere with the lobster fishery by eating bait set out in traps.
