Pontella
''Pontella'' is a marine copepod genus in the family Pontellidae. It is an organism that bears three lenses in the eye. The outer has a parabolic surface, countering the effects of spherical aberration while allowing a sharp image to be formed. ''Pontella'' includes the following species: *'' Pontella agassizii'' Giesbrecht, 1895 *'' Pontella alata'' A. Scott, 1909 *''Pontella andersoni'' Sewell, 1912 *''Pontella argentea'' Dana, 1849 *'' Pontella asymmetrica'' Heinrich, 1967 *'' Pontella atlantica'' (Milne-Edwards, 1840) *''Pontella bairdii'' Lubbock, 1853 *''Pontella barbata'' Tanaka, 1936 *''Pontella bifurcata'' Tanaka, 1936 *''Pontella bonei'' Mulyadi, 2003 *''Pontella brachiata'' Dana, 1849 *'' Pontella brachyura'' (Kroyer, 1849) *'' Pontella brevicornis'' (Lubbock, 1857) *''Pontella cerami'' A.

Calanoida
Calanoida is an order of copepods, a group of arthropods commonly found as zooplankton. The order includes around 46 families with about 1800 species of both marine and freshwater copepods between them. Description Calanoids can be distinguished from other planktonic copepods by having first antennae at least half the length of the body and biramous second antennae. However, their most distinctive anatomical trait is the presence of a joint between the fifth and sixth body segments. The largest specimens reach long, but most do not exceed long. Classification Calanoida contains the following families, as well as the genus '' Microdisseta'' (which is currently ''incertae sedis''); * Acartiidae * Aetideidae * Arctokonstantinidae * Arietellidae * Augaptilidae * Bathypontiidae * Calanidae * Calocalanidae * Candaciidae * Centropagidae * Clausocalanidae * Diaixidae * Diaptomidae * Discoidae * Epacteriscidae * Eucalanidae * Euchaetidae * Fosshageniidae * Heterorha ...

James Dwight Dana
James Dwight Dana FRS FRSE (February 12, 1813 – April 14, 1895) was an American geologist, mineralogist, volcanologist, and zoologist. He made pioneering studies of mountain-building, volcanic activity, and the origin and structure of continents and oceans around the world. His zoological author abbreviation is Dana. Early life and career Dana was born February 12, 1813, in Utica, New York. His father was merchant James Dana (1780–1860) and his mother was Harriet Dwight (1792–1870). Through his mother he was related to the Dwight New England family of missionaries and educators including uncle Harrison Gray Otis Dwight and first cousin Henry Otis Dwight. He showed an early interest in science, which had been fostered by Fay Edgerton, a teacher in the Utica high school, and in 1830 he entered Yale College in order to study under Benjamin Silliman the elder. Graduating in 1833, for the next two years he was teacher of mathematics to midshipmen in the Navy, and sailed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic (inhabiting sea waters), some are benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult and then, after more molts, achieves adult development. The nauplius form is so ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List ...
