Halocypridina
Halocypridina is a suborder of seed shrimp in the order Halocyprida. Ostracods of this group often have a dorsoposterior spine on the carapace. The adductor muscle scars show various patterns, in contrast to those of the Cladocopina, which are in a triangular pattern (three scars) or a half-rosette (15 scars). A sixth limb is present (absent in Cladocopina). The group is divided into the Halocypridae and the Thaumatocyprididae ''Thaumatocyprididae'' is a family of ostracods in the order Halocyprida The Halocyprida is one of the two orders within the Myodocopa, in turn a subclass of the ostracods.

Like their relatives in the order Myodocopida, they have a long exopod on the second antenna. However, unlike myodocopids, their fifth appendage is leg-like rather than modified for feeding, their seventh limb is reduced or absent, and they have no lateral eyes. The group is primarily planktonic. There are two suborders: Halocypridina and Cladocopina.

Halocypridae
Halocypridae is a family of ostracods belonging to the order Halocyprida. This family contains bioluminescent members such as ''Conchoecia pseudodiscophora'', which are believed to use coelenterazine and a coelenterazine luciferase rather than vargulin.

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] |

Seed Shrimp
Ostracods, or ostracodes, are a class of the Crustacea (class Ostracoda), sometimes known as seed shrimp. Some 70,000 species (only 13,000 of which are extant) have been identified, grouped into several orders. They are small crustaceans, typically around in size, but varying from in the case of ''Gigantocypris''. Their bodies are flattened from side to side and protected by a bivalve-like, chitinous or calcareous valve or "shell". The hinge of the two valves is in the upper (dorsal) region of the body. Ostracods are grouped together based on gross morphology. While early work indicated the group may not be monophyletic and early molecular phylogeny was ambiguous on this front, recent combined analyses of molecular and morphological data found support for monophyly in analyses with broadest taxon sampling. Ecologically, marine ostracods can be part of the zooplankton or (most commonly) are part of the benthos, living on or inside the upper layer of the sea floor. While Myodoco ...

American Geophysical Union
The American Geophysical Union (AGU) is a 501(c)(3) nonprofit organization of Earth, atmospheric, ocean, hydrologic, space, and planetary scientists and enthusiasts that according to their website includes 130,000 people (not members). AGU's activities are focused on the organization and dissemination of scientific information in the interdisciplinary and international fields within the Earth and space sciences. The geophysical sciences involve four fundamental areas: atmospheric and ocean sciences; solid-Earth sciences; hydrologic sciences; and space sciences. The organization's headquarters is located on Florida Avenue in Washington, D.C. History The AGU was established in December 1919 by the National Research Council (NRC) to represent the United States in the International Union of Geodesy and Geophysics (IUGG), and its first chairman was William Bowie of the United States Coast and Geodetic Survey (USCGS). For more than 50 years, it operated as an unincorpora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
