  1. \U"ni*valve\, n. [Uni- + valve: cf. F. univalve.]
    A shell consisting of one valve only; a mollusk whose shell
    is composed of a single piece, as the snails and conchs.
    Note: Most univalves are spiral and are the shells of
          gastropods, but many belong to cephalopods and
          pteropods. A large number of univalves belonging to the
          gastropods are conical, cup-shaped, or shieldlike, as
          the limpets.
