gastrula, n:
Gastrula
(gcide)
Gastrula \Gas"tru*la\, n.; pl. Gastrul[ae][NL., dim. fr. Gr. ?
the stomach.] (Biol.)
An embryonic form having its origin in the invagination or
pushing in of the wall of the planula or blastula (the
blastosphere) on one side, thus giving rise to a
double-walled sac, with one opening or mouth (the blastopore)
which leads into the cavity (the archenteron) lined by the
inner wall (the hypoblast). See Illust. under Invagination.
In a more general sense, an ideal stage in embryonic
development. See Gastr[ae]a. -- a. Of or pertaining to a
gastrula.
[1913 Webster]
gastrula
(gcide)
Planula \Plan"u*la\, n.; pl. Planul[ae]. [L., a little plane.]
1. (Biol.) In embryonic development, a vesicle filled with
fluid, formed from the morula by the divergence of its
cells in such a manner as to give rise to a central space,
around which the cells arrange themselves as an envelope;
an embryonic form intermediate between the morula and
gastrula. Sometimes used as synonymous with gastrula.
[1913 Webster]

2. (Zool.) The very young, free-swimming larva of the
c[oe]lenterates. It usually has a flattened oval or oblong
form, and is entirely covered with cilia.
[1913 Webster]
Gastrula
(gcide)
Stomapoda \Sto*map"o*da\, n. pl. [NL. See Stoma, and -poda.]
(Zool.)
An order of Crustacea including the squillas. The maxillipeds
are leglike in form, and the large claws are comblike. They
have a large and elongated abdomen, which contains a part of
the stomach and heart; the abdominal appendages are large,
and bear the gills. Called also Gastrula, Stomatopoda,
and Squilloidea.
[1913 Webster]
gastrula
(wn)
gastrula
n 1: double-walled stage of the embryo resulting from
invagination of the blastula; the outer layer of cells is
the ectoderm and the inner layer differentiates into the
mesoderm and endoderm
