Brachycnemina
Brachycnemina is a suborder of zoanthids in the order Zoantharia. Genetic analysis has been used to suggest Brachycnemina is a monophyletic group diverging within the paraphyletic Macrocnemina. Characteristics Brachycnemia species habitate most environments, ranging from shallow tropical reefs to cold seeps in the deep sea. It forms large colonies on intertidal and shallow reef crests. Due to the members of this suborder being loosely collected, there are no standard characteristics uniting them besides slight morphological, ecological and phylogenetic differences. Subdivisions This suborder counts with 3 taxonomic families, namely Neozoanthidae, which is monogeneric; Sphenopidae, which includes sand-encrusted and colonial specimens like the commonly found ''Palythoa'' and ''Sphenopus'', itself found in a few discrete areas; and Zoanthidae Zoanthidae is a family of cnidarians. Genera include: * '' Acrozoanthus'' Saville-Kent, 1893 * '' Isaurus'' Gray, 1828 * ''Zoanthus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palythoa Grandis
''Palythoa'' is a genus of anthozoans in the order Zoantharia.Reimer, J. (2018). Palythoa Lamouroux, 1816. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=205785 on 2018-08-27 Description The polyps of ''Palythoa'' are partially embedded in an encrusting mat of tissue (coenenchyme) covering the substrate on which the colony grows. The individual polyps have flattened oral discs surrounded by a fringe of tentacles. The tentacles' shape and size can vary considerably between species, and even between colonies of the same species. Their colors are also highly variable, with relatively dull shades like cream, coffee, white, brown, or yellow, being the most common. Fluorescent colored colonies also exist, but these are more rare. Palytoxin Palytoxin is a highly toxic fatty alcohol produced by many species of ''Palythoa'', and is also found in other corals and certain marine invertebrates. The substance was first isolate ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Cnidarian
Cnidaria () is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments, predominantly the latter. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. Cnidarians mostly have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes. Both forms have a single orifice and body cavity that are used for digestion and respiration. Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors. Several free-swimming species of Cubozoa and Scyphozo ...
