Himantolophus Kalami
''Himantolophus kalami'' is a species of marine Actinopterygii, ray-finned fish belonging to the Family (biology), family Himantolophidae, the footballfishes. This species was Species description, described in 2022 by Melapurra Rajeeshkumar, Theodore Wells Pietsch III and Naryanane Saravanane with its Type locality (biology), type locality given as the east coast of the northern Andaman and Nicobar Islands, India. This species is a member of the ''Himantolophus albinares'' species complex, a classification partly based on the absence of anterior Esca (fish anatomy), escal appendages. It differs from other species in this complex in having a unique Illicium (fish anatomy), illicial and escal morphology having a simple lower central filament and a pair of filaments on each side of the base the esca. Etymology The Specific name (zoology), specific name honours A. P. J. Abdul Kalam, the 11th president of India from 2002 to 2007, who was also an Indian Aerospace engineering, aerospace ...

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as plant variety (botany), varieties), which may be a complex ranking but it is not a species complex. In most cases, a specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Naryanane Saravanane
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep Sea Fish
Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep-sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout. Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor. Deep-sea organisms generally inhabit bathypelagic ( deep) and abyssopelagic ( deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic ( deep) zone as well. The mesopelagic zone is the disphotic zone, meaning light there is minimal but still measurable. The oxygen minimum layer exists somewhere between a depth of depending on the place in the ocean. This area is also where nutrients are most abundant. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerospace Engineering
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, air propulsion, avionics, materials science, st ...

President Of India
The president of India (ISO 15919, ISO: ) is the head of state of the Republic of India. The president is the nominal head of the executive, the first citizen of the country, and the commander-in-chief, supreme commander of the Indian Armed Forces. Droupadi Murmu is the 15th and current president, having taken office on 25 July 2022. The office of president was created when Constitution of India, India's constitution came into force and it became a republic on Republic Day (India), 26 January 1950. The president is indirect election, indirectly elected by an electoral College (India), electoral college comprising both houses of the Parliament of India and the state Legislative Assembly (India), legislative assemblies of each of States and union territories of India, India's states and territories, who themselves are all directly elected by the citizens. s:Constitution of India/Part V#Article 53 %7BExecutive power of the Union%7D, Article 53 of the Constitution of India stat ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) 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". Etymology 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 ...

Illicium (fish Anatomy)
The anglerfish are ray-finned fish in the order Lophiiformes (). Both the order's common name, common and scientific name comes from the characteristic mode of predation, in which a modified dorsal Fish fin#Ray-fins, fin ray acts as a Aggressive mimicry#Food as an attractant, lure for prey (akin to a human Angling, angler, and likened to a crest or "''wikt:Lophius, lophos''"). The modified fin ray, with the very tip being the Esca (fish anatomy), esca and the length of the structure the Illicium (fish anatomy), illicium, is adapted to attract specific prey items across the families of anglerfish by using different luring methods. Anglerfish occur worldwide. The majority are bottom-dwellers, being demersal fish, while the aberrant deep-sea anglerfish are Pelagic fish, pelagic, (mostly) living high in the water column. Some live in the Deep-sea fish, deep sea (such as the deep-sea anglerfish and sea toads), while others live in Shallow water marine environment, shallower waters, s ...
