Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals and soft corals. Adult anthozoans are all attached to the seabed, while their larvae can disperse as part of the plankton; the basic unit of the adult is the polyp. Sea anemones are solitary, but the majority of corals are colonial, being formed by the budding of new polyps from an original, founding individual. Colonies are strengthened by calcium carbonate and other materials and take various massive, plate-like, bushy or leafy forms. Anthozoa is included within the phylum Cnidaria, which includes the jellyfish, box jellies and parasitic Myxozoa and Polypodiozoa; the two main subclasses of Anthozoa are the Hexacorallia, members of which have six-fold symmetry and includes the stony corals, sea anemones, tube anemones and zoanthids. The smaller subclass, consists of the tube-dwelling anemones; some additional species are included as incertae sedis until their exact taxonomic position can be ascertained. Anthozoans are carnivores.
Many species supplement their energy needs by making use of photosynthetic single-celled algae that live within their tissues. These species live in shallow water and many are reef-builders. Other species lack the zooxanthellae and, having no need for well-lit areas live in deep-water locations. Unlike other members of this phylum, anthozoans do not have a medusa stage in their development. Instead, they release sperm and eggs into the water. After fertilisation, the planula larvae form part of the plankton; when developed, the larvae settle on the seabed and attach to the substrate, undergoing metamorphosis into polyps. Some anthozoans can reproduce asexually through budding or by breaking in pieces. More than 16,000 species have been described; the name "Anthozoa" comes from the Greek words άνθος and ζώα, hence ανθόζωα = "flower animals", a reference to the floral appearance of their perennial polyp stage. Anthozoans are marine, include sea anemones, stony corals, soft corals, sea pens, sea fans and sea pansies.
Anthozoa is the largest taxon of cnidarians. They range in size from small individuals less than half a centimetre across to large colonies a metre or more in diameter, they include species with a wide range of forms that build and enhance reef systems. Although reefs and shallow water environments exhibit a great array of species, there are in fact more species of coral living in deep water than in shallow, many taxa have shifted during their evolutionary history from shallow to deep water and vice versa. Anthozoa is subdivided into three subclasses: Octocorallia and Ceriantharia, which form monophyletic groups and show differentiating reflections on symmetry of polyp structure for each subclass; the relationships within the subclasses are unresolved. The "Ceriantipatharia" was thought to be a separate subclass but, of the two orders it comprised, Antipatharia is now considered part of Hexacorallia and Ceriantharia is now considered an independent subclass; the extant orders are shown to the right.
Hexacorallia includes coral reef builders: the stony corals, sea anemones, zoanthids. Genetic studies of ribosomal DNA has shown Ceriantharia to be a monophyletic group and the oldest, or basal, order among them. Classification according to the World Register of Marine Species: subclass Hexacorallia order Actiniaria — sea anemones order Antipatharia — black coral order Corallimorpharia — corallimorphs order Rugosa † order Scleractinia — stony corals order Zoantharia — zoanthids subclass Octocorallia order Alcyonacea — soft corals and gorgonians order Helioporacea — blue corals order Pennatulacea — pennatules, sea feathers, sea pens, sea pansies subclass Ceriantharia — ceriantharians, tube-dwelling anemones order Penicillaria order Spirularia Anthozoa incertae sedis genus Aiptasiodes order Auloporida † genus Sarcinula †Octocorallia comprises the sea pens, soft corals, blue coral. Sea whips and sea fans, known as gorgonians, are part of Alcyonacea and were divided into separate orders. Ceriantharia comprises the related tube-dwelling anemones.
Tube-dwelling anemones or cerianthids look similar to sea anemones, but belong to an different subclass of anthozoans. They are solitary. Tube anemones live and can withdraw into tubes, which are made of a fibrous material, made from secreted mucus and threads of nematocyst-like organelles, known as ptychocysts; the basic body form of an anthozoan is the polyp. This consists of a tubular column topped by the oral disc, with a central mouth. In solitary individuals, the base of the polyp is the foot or pedal disc, which adheres to the substrate, while in colonial polyps, the base links to other polyps in the colony; the mouth leads into a tubular pharynx which descends for some distance into the body before opening into the coelenteron, otherwise known as the gastrovascular cavity, that occupies the interior of the body. Internal tensions pull the mouth into a slit-shape, the ends of the slit lead into two grooves in the pharynx wall called siphonoglyphs; the coelenteron is subdivided by a number of vertical partitions, known as mesenteries or septa.
Some of these extend from the body wall

The United States Senate election of 1960 in Massachusetts was held on November 8, 1960 with Republican Incumbent Leverett Saltonstall defeating his challengers. Edmund C. Buckley, Middlesex County Register of Deeds Foster Furcolo, Governor of Massachusetts Thomas J. O'Connor, Mayor of Springfield Edmund Dinis, District Attorney Governor Foster Furcolo, who lost to Saltonstall in 1954, decided to run against him again in 1960. On June 15, 1960, Springfield Mayor Thomas J. O'Connor announced he would challenge Furcolo for the Democratic nomination. O'Connor received support from Democrats who were opposed to Furcolo's effort to enact a state sales tax. Edmund Dinis, District Attorney for the southern district, was in the race, but dropped at the party convention to support O'Connor. In a show of unity, Furcolo was nominated at the convention by Massachusetts Senate President and political foe John E. Powers. Furcolo defeated O'Connor by a 3 to 1 margin at the Democratic State Convention, but O'Connor decided to remain in the race.
In the primary, O'Connor upset Furcolo 48% to 39% with Southern Middlesex County Register of Deeds Edmund C. Buckley received the remaining 13%. O'Connor was able to sweep the western part of top Furcolo by 10,000 in Boston. During the general election, O'Connor contrasted his youth to Saltonstall's age, calling him "yesterday's senator" and "The Late George Apley of Massachusetts politics". O'Connor attacked the senator for "fail to act for the working man" and for helping "big business brigands" destroy the state's textile industry. Saltonstall ran on his long record of public service, he criticized O'Connor for stating that he would consider continue serving as Springfield mayor if elected to the Senate, arguing that Americans need "not part-time leadership but full leadership". Saltonstall criticized O'Connor's campaign for lacking substance. After refusing to debate O'Connor, Saltonstall stated "If my opponent would express his opinions of some of the vital national and international issues, I would consider whether I would debate on these subjects or not".
Saltonstall defeated O'Connor 1,358,556 votes to 1,050,725 to hold on to his Senate seat
