Dinochelus
''Dinochelus ausubeli'' is a small deep sea lobster discovered in 2007 in the Philippines during the Census of Marine Life and described in 2010 in the new genus ''Dinochelus''. Its two claws are very different in size, are elongated, and bear many long teeth on the inner surface. Description ''Dinochelus ausubeli'' has a carapace length of around , and is in life mostly translucent white, with reddish pink colouring near the middle of the carapace, on the tail fan, on the antennae, and on the first pereiopods (including the claws). Its two claws are very different in size. Distribution and discovery ''D. ausubeli'' is only known from its type locality, , off the coast of Luzon in the Philippines. It was found by trawling at a depth of around in 2007, as part of the Census of Marine Life, a major effort to document marine life in the first decade of the 21st century. It was described in 2010 by an international team of scientists. Taxonomy The new species was placed in a sep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lobster
Lobsters are a family (biology), family (Nephropidae, Synonym (taxonomy), synonym Homaridae) of marine crustaceans. They have long bodies with muscular tails and live in crevices or burrows on the sea floor. Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others. Highly prized as seafood, lobsters are economically important and are often one of the most profitable commodities in coastal areas they populate. Commercially important species include two species of ''Homarus'' from the northern Atlantic Ocean and scampi (which look more like a shrimp, or a "mini lobster")—the Northern Hemisphere genus ''Nephrops'' and the Southern Hemisphere genus ''Metanephrops''. Distinction Although several other groups of crustaceans have the word "lobster" in their names, the unqualified term "lobster" generally refers to the clawed lobsters of the family Nephropidae. Clawed lobsters are not closely related to spiny lobsters o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epistome
Stomotheca is the term applied to the feeding apparatus in front of the mouth of harvestmen, and sometimes the related scorpions. Usually it consists of the ''epistome'' ( labrum), two pairs of ''coxapophyses'' (endites, maxillary lobes) and often a '' labium''. (2007): Morphology and Functional Anatomy. In: Pinto-da-Rocha ''et al.'' 2007: 23ff The ''epistome'' is a projection that forms the anterior wall of the stomotheca. Its upper side is hardened and divided by a transverse invagination ( sulcus). The part nearer the groove is sometimes called clypeus, the other one labrum. The area around the mouth is soft and flexible, often with a distal lobe. On the sides, the walls around the mouth are fused to the medial surfaces of the pedipalpal coxae, and a transverse muscle attaches to the inner surfaces of the epistomal walls. ''Coxapophyses'' are extensions from the pedipalps and first pair of legs. While hardened at the base, they end in large soft pads that work as lips. It some ...

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Cytochrome Oxidase
The enzyme cytochrome c oxidase or Complex IV, (was , now reclassified as a translocasEC 7.1.1.9 is a large transmembrane protein complex found in bacteria, archaea, and mitochondria of eukaryotes. It is the last enzyme in the respiratory electron transport chain of cells located in the membrane. It receives an electron from each of four cytochrome c molecules and transfers them to one oxygen molecule and four protons, producing two molecules of water. In addition to binding the four protons from the inner aqueous phase, it transports another four protons across the membrane, increasing the transmembrane difference of proton electrochemical potential, which the ATP synthase then uses to synthesize ATP. Structure The complex The complex is a large integral membrane protein composed of several metal prosthetic sites and 14 protein subunits in mammals. In mammals, eleven subunits are nuclear in origin, and three are synthesized in the mitochondria. The complex contains two ...

DNA Sequencing
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thaumastochelopsis
The family Thaumastochelidae contains five known species of deep-sea lobsters, three in the genus ''Thaumastocheles'', and two in the genus ''Thaumastochelopsis''. The fifth species was discovered in the ten–year Census of Marine Life. These creatures are distinguished from other clawed lobsters by their blindness (an adaptation to deep-sea life), and by their single elongated, spiny chela. The family Thaumastochelidae is now more usually subsumed into the lobster family Nephropidae. The five species are as follows: *''Thaumastocheles'' **''Thaumastocheles dochmiodon'' Chan & de Saint Laurent, 1999 is found in the Timor Sea. **''Thaumastocheles japonicus'' Calman, 1913, the "Pacific pincer lobster", is endemic to the Sea of Japan. **''Thaumastocheles zaleucus'' Thomson, 1873, the "Atlantic pincer lobster" or "Atlantic deep-sea lobster", is endemic to the Caribbean region. *''Thaumastochelopsis'' **''Thaumastochelopsis brucei'' Ahyong, Chu & Chan, 2007 lives in the Coral Sea ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Claw
A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or tarsus for gripping a surface as they walk. The pincers of crabs, lobsters and scorpions, more formally known as their chelae, are sometimes called claws. A true claw is made of a hard protein called keratin. Claws are used to catch and hold prey in carnivorous mammals such as cats and dogs, but may also be used for such purposes as digging, climbing trees, self-defense and grooming, in those and other species. Similar appendages that are flat and do not come to a sharp point are called nails instead. Claw-like projections that do not form at the end of digits but spring from other parts of the foot are properly named spurs. Tetrapods In tetrapods, claws are made of keratin and consist of two layers. The unguis is the harder external layer, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
