Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia.

Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Bryozoa
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Most marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the marine bryozoans (Stenolaemata), freshwater bryozoans (Phylactolaemata), and mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. At least two genera are solitary (''Aethozooides'' and '' Monobryozoon''); the rest are colonial. The terms Polyzoa and Bryozoa were introduced in 1830 and 1831, respectively. Soon after it was named, another group of animals was discovered whose filtering mechanism looked similar, so it was included in Bryozoa until 1869, when the two groups ...

Gymnolaemata
Gymnolaemata are a class of Bryozoans. Gymnolaemata are sessile, mostly marine organisms and grow on the surfaces of rocks, kelp, and in some cases on animals, like fish. Zooids are cylindrical or flattened. The lophophore is protruded by action of muscles pulling on the frontal wall. This order includes the majority of living bryozoan species. Orders * Cheilostomata Busk, 1852 * Ctenostomatida The Ctenostomatida are an order of bryozoans in the class Gymnolaemata. The great majority of ctenostome species are marine, although '' Paludicella'' inhabits freshwater. They are distinguished from their close relatives, the cheilostomes, by ...

Cheilostomatida
Cheilostomatida, also called Cheilostomata, is an order of Bryozoa in the class Gymnolaemata. They are exclusively marine, colonial invertebrate animals. Cheilostome colonies are composed of calcium carbonate and grow on a variety of surfaces, including rocks, shells, seagrass and kelps. The colony shapes range from simple encrusting sheets to erect branching and even unattached forms. As in other bryozoan groups, each colony is composed of a few to thousands of individual polypides. Each individual has a U-shaped gut, and no respiratory, circulatory, or nerve system. Unique among bryozoans, cheilostome polypides are housed in a box-shaped zooids, which do not grow larger once the zooid is mature. The opening through which the polypide protrudes is protected by a calcareous or chitinous lidlike structure, an operculum. Cheilostomes possess avicularia, which have modified the operculum into a range of mandibles (possibly for defense) or hair-like setae (possibly for cleaning). ...

Ascophora
Ascophora is an infraorder under order Cheilostomatida of the Bryozoa. They are now considered a synonym of Flustrina. Ascophorans are distinguished from other cheilostomes in having a completely calcified wall covering their frontal surface apart from the orifice, and possessing an ascus (hence the name of the suborder). The ascus is a water-filled sac of frontal membrane opening at or near the orifice. It functions as a hydrostatic system by allowing water into the space below the inflexible frontal wall when the zooid everts its polypide (feeding tentacles) by muscles pulling the frontal membrane inwards (non-ascophorans do not need this structure as their frontal wall is not calcified). The structure of this frontal wall is the basis of distinguishing the four major subdivisions of the Ascophora, each of which is, however, currently under suspicion of being polyphyletic and/or paraphyletic.Gordon, D.P. 2000.

George Busk
George Busk FRS FRAI (12 August 1807 – 10 August 1886) was a British naval surgeon, zoologist and palaeontologist. Early life, family and education Busk was born in St. Petersburg, Russia. He was the son of the merchant Robert Busk and his wife Jane. Robert Busk was the son of Sir Wadsworth Busk, who was an Attorney General of the Isle of Man. Jane Busk's father, John Westly, was Customs House clerk in St. Petersburg. He studied at Dr. Hartley's School in Yorkshire. He studied surgery in London, at both St Thomas' Hospital and for one session at St Bartholomew's Hospital. Career Busk was appointed assistant-surgeon to the Greenwich Hospital in 1832. He served as naval surgeon first in . He later served for many years in , which had fought at Trafalgar. In Busk's time it was used by the Seamen's Hospital Society as a hospital ship for ex-members of the Merchant Navy or fishing fleet and their dependants. During this period Busk made important observations on cholera and on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
