Stoloniferous :: Stolon (n.) An extension of the integument of the body, or of the body wall, from which buds are developed, giving rise to new zooids, and thus forming a compound animal in which the zooids usually remain united by the stolons. Such stolons are often present in Anthozoa, Hydroidea, Bryozoa, and social ascidians. See Illust. under Scyphistoma..

Sporosac :: Sporosac (n.) A hydrozoan reproductive zooid or gonophore which does not become medusoid in form or structure. See Illust. under Athecata.

Foraminifera :: Foraminifera (n. pl.) An extensive order of rhizopods which generally have a chambered calcareous shell formed by several united zooids. Many of them have perforated walls, whence the name. Some species are covered with sand. See Rhizophoda..

Polyzoon :: Polyzoon (n.) One of the individual zooids forming the compound organism of a polyzoan.

Sporophore :: Sporogony (n.) The growth or development of an animal or a zooid from a nonsexual germ.

Zooid :: Zooid (n.) An animal in one of its inferior stages of development, as one of the intermediate forms in alternate generation..

Porpita :: Porpita (n.) A genus of bright-colored Siphonophora found floating in the warmer parts of the ocean. The individuals are round and disk-shaped, with a large zooid in the center of the under side, surrounded by smaller nutritive and reproductive zooids, and by slender dactylozooids near the margin. The disk contains a central float, or pneumatocyst..

Systematic :: System (n.) One of the stellate or irregular clusters of intimately united zooids which are imbedded in, or scattered over, the surface of the common tissue of many compound ascidians..

Individual :: Individual (n.) An independent, or partially independent, zooid of a compound animal..

Proliferous :: Proliferous (a.) Producing sexual zooids by budding; -- said of the blastostyle of a hydroid.

Sporocyst :: Sporocyst (n.) An asexual zooid, usually forming one of a series of larval forms in the agamic reproduction of various trematodes and other parasitic worms. The sporocyst generally develops from an egg, but in its turn produces other larvae by internal budding, or by the subdivision of a part or all of its contents into a number of minute germs. See Redia..

Ascidiozooid :: Ascidiozooid (n.) One of the individual members of a compound ascidian. See Ascidioidea.

Protozoon :: Protozoon (n.) A single zooid of a compound protozoan.

Siphonophora :: Siphonophora (n. pl.) An order of pelagic Hydrozoa including species which form complex free-swimming communities composed of numerous zooids of various kinds, some of which act as floats or as swimming organs, others as feeding or nutritive zooids, and others as reproductive zooids. See Illust. under Physallia, and Porpita..
