\Sal"pa\ (s[a^]l"p[.a]), n.; pl. L. {Salp[ae]} (-p[=e]),
E. {Salpas} (-p[.a]z). [NL.: cf. L. salpa a kind of
stockfish.] (Zo["o]l.)
A genus of transparent, tubular, free-swimming oceanic
tunicates found abundantly in all the warmer latitudes. See
Illustration in Appendix.
Note: Each species exists in two distinct forms, one of which
      lives solitary, and produces, by budding from an
      internal organ, a series of the other kind. These are
      united together, side by side, so as to form a chain,
      or cluster, often of large size. Each of the
      individuals composing the chain carries a single egg,
      which develops into the solitary kind.
