Thomas Elliot Bowman III
Thomas Elliot Bowman III (October 21, 1918 – August 10, 1995) was an American carcinologist best known for his studies of isopods and copepods. Bowman was born and grew up in Brooklyn, New York (state), New York. He graduated from Kent School in Kent, Connecticut in 1937 and Harvard College in 1941. During the World War II, Second World War, he spent four years in the United States Army, U.S. Army, gaining a degree in veterinary medicine from the University of Pennsylvania. Afterwards, he went to the University of California, Berkeley, where he gained a master's degree, and then worked at the Scripps Institution of Oceanography, where he gained a Doctor of Philosophy, Ph.D. (awarded by the University of California, Los Angeles). During his career, Bowman wrote 163 papers, using a style which has been likened to that of Ernest Hemingway and Albert Camus. As well as describing 116 new species (including 55 isopods, 28 copepods, one suctorian and one Chaetognatha, chaetognath), 16 ge ...

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. 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.

Suwanee River
The Suwannee River (also spelled Suwanee River) is a river that runs through south Georgia (U.S. state), Georgia southward into Florida in the southern United States. It is a wild blackwater river, about long.U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed April 18, 2011 The Suwannee River is the site of the prehistoric Gulf Trough, Suwanee Straits that separated the Florida Panhandle, panhandle from the continent. Geography The headwaters of the Suwannee River are in the Okefenokee Swamp in the town of Fargo, Georgia. The river runs southwestward into the Florida Panhandle, then drops in elevation through limestone layers into a rare Florida whitewater rapid. Past the rapid, the Suwanee turns west near the town of White Springs, Florida, then connects to the confluences of the Alapaha River and Withlacoochee River (Suwannee River), Withlacoochee River. The confluences of these three rivers form the southern borderlin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crustaceans Of The United States
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their ...

Cave Crustaceans
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Asellota
Asellota is a suborder of isopod crustaceans found in marine and freshwater environments. Roughly one-quarter of all marine isopods belong to this suborder. Members of this suborder are readily distinguished from other isopods by their complex copulatory apparatus. Other characteristics include six-jointed antennal peduncle, the styliform uropods (a character shared with some other isopod groups), the fusion of pleonites 5, 4 and sometimes 3 to the pleotelson, and absence of the first pleopod in females. Classification The suborder Asellota comprises these families: Some classifications also include the Microcerberidea within Asellota.

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 of ...

Ochlockonee River
The Ochlockonee River ( ) is a fast running river, except where it has been dammed to form Lake Talquin in Florida, originating in Georgia and flowing for before terminating in Florida. Background The name is from the Hitchiti language words for yellow river. The Ochlockonee originates south of the town of Sylvester in Worth County in southwest Georgia and empties into Ochlockonee Bay and then Apalachee Bay in Florida. The river forms the western boundaries of Leon County and Wakulla County and eastern boundaries of Gadsden County, Liberty County, and Franklin County in Florida. It flows through the Red Hills, the Jackson Bluff Dam, Talquin State Forest, Lake Talquin State Park and the Apalachicola National Forest, and past Ochlockonee River State Park, where it is tidally influenced and a mixture of fresh, brackish, and salt water, on the way to its terminus in Ochlockonee Bay, which then empties into Apalachee Bay, with tidal influences extending upstream over from ...
