    Statoblast \Stat"o*blast\ (st[a^]t"[-o]*bl[a^]st), n. [Gr.
    stato`s standing (i. e., remaining) + -blast.] (Zo["o]l.)
    One of a peculiar kind of internal buds, or germs, produced
    in the interior of certain Bryozoa and sponges, especially in
    the fresh-water species; -- also called {winter buds}.

    Note: They are protected by a firm covering, and are usually
    destined to perpetuate the species during the winter
    season. They burst open and develop in the spring. In
    some fresh-water sponges they serve to preserve the
    species during the dry season. See Illust. under
    {Phylactol[ae]mata}.
