Sea snail is a common name for snails that normally live in saltwater- marine gastropod molluscs. (The taxonomic class Gastropoda also includes snails that live in other habitats, i.e. land snails and freshwater snails.)
Sea snails are marine gastropods with shells. Those marine gastropods with no shells, or only internal shells, are variously known by other common names, including sea slug, sea hare, nudibranch, etc.
Many sea snails are edible and are exploited as food sources by humans.
Diversity within sea snails is enormous. Many very different clades of gastropods are either dominated by, or consist exclusively of, sea snails. Because of this great variability, generalization about the feeding, reproduction, habitat, or other traits of sea snails is not possible. Instead, individual clades, families, genera, or species must be assessed.

Famous quotes containing the words sea and/or snail:
“Translation is entirely mysterious. Increasingly I have felt that the art of writing is itself translating, or more like translating than it is like anything else. What is the other text, the original? I have no answer. I suppose it is the source, the deep sea where ideas swim, and one catches them in nets of words and swings them shining into the boat ... where in this metaphor they die and get canned and eaten in sandwiches.”
—Ursula K. Le Guin (b. 1929)
“The snail in his museum
wears his mother all day,
he hides his mysterious bottom
as if it were rotten fruit.”
—Anne Sexton (1928–1974)
