Sertularella Gayi
''Sertularella gayi'' is a branching colonial hydroid in the family Sertulariidae.WoRMS (2017)''Sertularella gayi'' (Lamouroux, 1821).In: Schuchert, P. (2017). World Hydrozoa database. Accessed through: World Register of Marine Species on 2018-02-03. Description The main stems of the colony are bright yellow and relatively thick, composed of several fibres adhering to each other at the base, becoming monosiphonic with alternating zooids in the upper part of the colony. The side branches are approximately alternate and support the hydrothecae which are regularly alternate, one to each internode. As in ''Sertularella polyzonias'' they are bulbous in the basal region, and the margin is quadridentate. The operculum consists of four triangular flaps. The gonothecae are oval shaped, and the upper portion has transverse ridges whilst the lower portion is smooth. The aperture is bidentate. Distribution The type locality for this species is the English Channel coast of France, from P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Vincent Félix Lamouroux
Jean Vincent Félix Lamouroux (3 May 1779 – 26 March 1825) was a French biologist and naturalist, noted for his seminal work with algae. Biography Lamouroux was born in Agen in the Aquitaine of southwestern France, the son of Claude Lamouroux, an intellectual who made his livelihood in manufacturing, but who was also a musician, a one-term mayor of Agen, and a co-founder of the Academic Society of Agen. Jean Vincent Lamouroux studied botany at the Boudon de Saint-Amans school in Agen. Lamouroux was particularly interested in marine organisms such as algae and hydrozoans. In 1805 he published a dissertation on several species of ''Fucus'' before settling in Paris in 1807, after his father went into bankruptcy. In 1807, Lamouroux was appointed to the French Academy of Sciences and in 1808 he became assistant professor of natural history at the University of Caen, rising to full professorship by 1811. He joined the Linnean Society of Calvados and contributed to its publications, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrozoa
Hydrozoa (hydrozoans; ) are a taxonomic class of individually very small, predatory animals, some solitary and some colonial, most of which inhabit saline water. The colonies of the colonial species can be large, and in some cases the specialized individual animals cannot survive outside the colony. A few genera within this class live in freshwater habitats. Hydrozoans are related to jellyfish and corals and belong to the phylum Cnidaria. Some examples of hydrozoans are the freshwater jelly (''Craspedacusta sowerbyi''), freshwater polyps ('' Hydra''), ''Obelia'', Portuguese man o' war (''Physalia physalis''), chondrophores (Porpitidae), "air fern" (''Sertularia argentea''), and pink-hearted hydroids (''Tubularia''). Anatomy Most hydrozoan species include both a polyp (zoology), polypoid and a medusa (biology), medusoid stage in their lifecycles, although a number of them have only one or the other. For example, ''Hydra'' has no medusoid stage, while ''Liriope tetraphylla, Lir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
