Iphinoe Trispinosa
''Iphinoe trispinosa'' is a species of cumacean belonging to the family Bodotriidae and the genus ''Iphinoe''. Anatomy ''I. trispinosa'' is a slender cumacean which grows up to 10 mm long. The carapace is approximately twice as long as it is high, and in the male, which has a rounded pseudorostrum, rather smooth. The female has two to six small serrations in the middle of the dorsal ridge of the carapace, and a sharply leading pseudorostrum. Both males and females are strongly pigmented. The male has — like all members of the family Bodotriidae — five pairs of pleopods. Their colour is whitish to straw-coloured. Habitat ''I. trispinosa'' are usually found in fine sand beaches, such as those formed by silt deposits. They prefer shallower depths, but may be found as deep as 150 m. During summer nights the males emerge from sand, swarming to the surface, frequently attracted by light. They are found from Norway to the Moroccan coast, around the Canary Islands a ...

Edinburgh New Philosophical Journal
The ''Edinburgh Philosophical Journal'' was founded by its editors Robert Jameson and David Brewster in 1819 as a scientific journal to publish articles on the latest science of the day. In 1826 the two editors fell out, and Jameson continued publication as the ''Edinburgh New Philosophical Journal''. Jameson died in 1854, and his place as editor was then taken over by Thomas Anderson, Sir William Jardine, John Hutton Balfour and, for America, Henry Darwin Rogers. In 1864 it was merged into the ''Quarterly Journal of Science'', London. The ''Edinburgh Philosophical Journal'' was published by Archibald Constable and Company, then in 1826 publication of the ''Edinburgh New Philosophical Journal'' was taken on by Adam Black, later A & C Black of Edinburgh. The journal covered emerging scientific developments in chemistry, optics, electricity, magnetism, and natural history, as well as related topics including practical mechanics, inventions, and scientific instruments. As well as ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cumacea
Cumacea is an order of small marine crustaceans of the superorder Peracarida, occasionally called hooded shrimp or comma shrimp. Their unique appearance and uniform body plan makes them easy to distinguish from other crustaceans. They live in soft-bottoms such as mud and sand, mostly in the marine environment. There are more than 1,500 species of cumaceans formally described. The species diversity of Cumacea increases with depth. Anatomy Cumaceans have a strongly enlarged cephalothorax with a carapace, a slim abdomen, and a forked tail. The length of most species varies from . The carapace of a typical cumacean is composed of several fused dorsal head parts and the first three somites of the thorax. This carapace encloses the appendages that serve for respiration and feeding. In most species, there are two eyes at the front side of the head shield, often merged into a single dorsal eye lobe. The five posterior somites of the thorax form the pereon. The pleon (abdomen) consists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bodotriidae
Bodotriidae is a family of crustaceans belonging to the order Cumacea. Bodotriids have a worldwide distribution in shallow and deep waters. There are over 380 described species in over 30 genera, being the most diverse cumacean family. Their external morphology differs from other cumaceans by a combination of traits that independently are not unique to the family: the telson is fused to the last abdominal segment (last pleonite), the dorsal part of the mandible has a boat shape (naviculoid), exopods exist on the third maxilliped and the first peraeopod, and there is a uropodal endopod with one or two articles. Anatomy In both sexes the telson is fused with the last segment of the pleon, forming a "pleotelson". Males generally have five pairs of pleopods, although less often there may be three, two or they may be entirely absent. In females the second antenna is substantially shorter than the first. The third maxillipeds always have exopods (outer branches), and there are endopo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Pleopod
The decapod ( crustaceans such as a crab, lobster, shrimp or prawn) is made up of 20 body segments grouped into two main body parts: the cephalothorax and the pleon (abdomen). Each segment may possess one pair of appendages, although in various groups these may be reduced or missing. They are, from head to tail: Cephalothorax Head # antennules # antennae #mandibles # first maxillae # second maxillae The head also bears the (usually stalked) compound eyes. The distal portion of a mandible or maxilla which has a sensory function is known as a palp. Thorax / pereon #first maxillipeds #second maxillipeds #third maxillipeds #first pereiopods #second pereiopods #third pereiopods #fourth pereiopods #fifth pereiopods Maxillipeds are appendages modified to function as mouthparts. Particularly in the less advanced decapods, these can be very similar to the pereiopods. Pereiopods are primarily walking legs and are also used for gathering food. They are also the ten legs from which decapo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mediterranean Sea
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.
