Molluscs
121
Distribution: Southeast England, Belgium to North Italy, Denmark, Estonia,
Greece, Ukraine (AnimalBase).
Habitat: Lives on water plants in
freshwater.
Description: Ram’s horn snails usually have shells formed like a disc or a
plate. The disc-shaped shell of a ram’s
horn snail usually is tilted to the left,
so the snail can carry it. So it appears
as if ram’s horn snails are coiled to
the right. The fact that genital opening and respiratory opening are on
the left shows that ram’s horn snails
indeed are sinistral (coiled to the left)
(Living World of Molluscs).

Nucella lapillus Linnaeus 1758
Order: Neogastropoda
Family: Muricidae
Common name: Dog whelk, Atlantic
dogwinkle.
Distribution: Throughout North Atlantic from the Arctic to the Algarve in the
east, Iceland and the Faroes, and from
Long Island north to Southwest Greenland in the west (BIOTIC).
Habitat: Rocky shores and estuarine
conditions.
Description: Shell is small, broadly
conical, bearing spiral ridges, and
consisting of a short, pointed spire,
dominated by the last whorl. Shell is
usually up to 3 cm in height by 2 cm
broad but may reach up to 6 cm in
height. Overall shell shape varies
quite widely according to the degree
of exposure to wave action of the shore
