NationMaster - Encyclopedia: Hydrozoa   (Site not responding. Last check: ) Phylum (plural: phyla) is a taxon used in the classification of animals, adopted from the Greek phylai the clan-based voting groups in Greek city-states. The term morphology in biology refers to the outward appearance (shape, structure, colour, pattern) of an organism or taxon and its component parts. In biology, a medusa (also known as a hydromedusa) is a form of cnidarian in which the body is shortened on its principal axis and broadened, sometimes greatly, in contrast with the hydroid or polyp. www.nationmaster.com /encyclopedia/Hydrozoa   (1345 words)

Spartanburg SC | GoUpstate.com | Spartanburg Herald-Journal In biological taxonomy, a phylum (Greek plural: phyla) is a taxon in the rank below kingdom and above class. Although the International Code of Botanical Nomenclature allows the use of the term "Phylum" in reference to plants, the term "Division" is almost always used by botanists. Many phyla are exclusively marine, and only one phylum is entirely absent from the world's oceans: the Onychophora or velvet worms. www.goupstate.com /apps/pbcs.dll/section?category=NEWS&template=wiki&text=phylum_(biology)   (657 words)

New Jersey Scuba Diver - Marine Biology - Invertebrates - Overview   (Site not responding. Last check: ) Cnidaria is a phylum of invertebrate animals comprising the sea anemones, corals, jellyfish, and hydroids. Annelida is a phylum of soft-bodied, bilaterally symmetrical, segmented animals, known as the segmented, or annelid, worms. In some primitive members of the phylum the metameres are identical, or very similar to one another, each containing the same structures; in more advanced forms there is a tendency toward a consolidation of some segments and a restriction of certain organs to particular segments. www.njscuba.net /biology/misc_ov_invertebrates.html   (3224 words)

Biology - Crystalinks Biology has become such a vast research enterprise that it is not generally regarded as a single discipline, but as a number of clustered sub-disciplines. For example, evolutionary biology leans heavily on techniques from molecular biology to determine DNA sequences, which assist in understanding the genetic variation of a population; and physiology borrows extensively from cell biology in describing the function of organ systems.Every living thing interacts with other organisms and its environment. Molecular biology is the study of biology at a molecular level. www.crystalinks.com /biologydefinition.html   (1996 words)

Augsburg College Biology - Photo of Month -December 2002 The green algae (phylum Chlorophyta) are closely related to the green plants and in fact are considered by many biologists to be true plants. In addition to many species of green macroalgae, this phylum also includes many microscopic species that live as single cells, or clusters or filaments of cells.

Biology of Sponges video guide. The phylum of sponges, Phylum Porifera, is entirely aquatic, with well over 98% of all sponge species found in marine environments, and a small percentage found in freshwater lakes and streams.

Cnidaria The mouth is surrounded by tentacles studded with microscopic stinging capsules known as nematocysts that are the agents of offense and defense. Life cycles of the Hydrozoa are the most diverse in the phylum: although the polyp is the more conspicuous and persistent stage in most taxa, some lack the medusa phase, whereas others lack the polyp phase. The cnida, or nematocyst, which is the sine qua non of the phylum, is secreted by the Golgi apparatus of a cell termed a cnidoblast (Watson 1988). www.tolweb.org /tree?group=Cnidaria&contgroup=Animals   (2407 words)

Phylum Arthropoda Phylum Arthropoda (arthro = joint; poda = foot) is the most numerous phylum of all living organisms, both in number of species and in number of individuals. The body feature from which the phylum takes its name is the jointed appendages, which include antennae and mouthparts as well as walking legs. It is thought that the early arthropod ancestors (descended from organisms that looked like marine worms or, later, Peripatus) looked sort of like a centipede: they had a number of body segments, each with a pair of jointed appendages. biology.clc.uc.edu /courses/bio106/arthrpod.htm   (2157 words)
