Etymology: "Shellfishes" is simply the plural of "shellfish," so the history belongs to the singular. "Shellfish" was inherited from Old English as "sċielfisċ," built from "sċiell" (shell) and "fisċ" (fish), and it passed into Middle English as "schellefyssch." Its meaning is plain and literal: a creature with a shell that lives in water and is eaten or collected, a sense the compound still carries today. Because the word is a compound of two ordinary English words, its parts explain it directly. The "shell" element is the hard outer covering, and "fish" is used in its broad older sense of any creature living in water, which is why the compound covers both mollusks and crustaceans. Crabs and lobsters, which have no shell in the snail sense but do have a hard exoskeleton, are grouped under the same name.

Synonyms: mollusks, crustaceans, shellfish, aquatic animals, marine life
