Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bony Fish
Osteichthyes ( ; ), also known as osteichthyans or commonly referred to as the bony fish, is a Biodiversity, diverse clade of vertebrate animals that have endoskeletons primarily composed of bone tissue. They can be contrasted with the Chondrichthyes (cartilaginous fish) and the extinct placoderms and acanthodians, which have endoskeletons primarily composed of cartilage. The vast majority of extant taxon, extant fish are members of Osteichthyes, being an extremely diverse and abundant group consisting of 45 order (biology), orders, over 435 family (biology), families and 28,000 species. The group is divided into two main clades, the ray-finned fish (Actinopterygii, which makes up the vast majority of extant fish) and the lobe-finned fish (Sarcopterygii, which gave rise to all land vertebrates, i.e. tetrapods). The oldest known fossils of bony fish are about 425 million years old from the late Silurian, which are also transitional fossils showing a dentition, tooth pattern th ...

Family
Family (from ) is a Social group, group of people related either by consanguinity (by recognized birth) or Affinity (law), affinity (by marriage or other relationship). It forms the basis for social order. Ideally, families offer predictability, structure, and safety as members mature and learn to participate in the community. Historically, most human societies use family as the primary purpose of Attachment theory, attachment, nurturance, and socialization. Anthropologists classify most family organizations as Matrifocal family, matrifocal (a mother and her children), patrifocal (a father and his children), wikt:conjugal, conjugal (a married couple with children, also called the nuclear family), avuncular (a man, his sister, and her children), or Extended family, extended (in addition to parents, spouse and children, may include Grandparent, grandparents, Aunt, aunts, Uncle, uncles, or Cousin, cousins). The field of genealogy aims to trace family lineages through history. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmonidae
Salmonidae (, ) is a family (biology), family of ray-finned fish, the only extant member of the suborder Salmonoidei, consisting of 11 extant genera and over 200 species collectively known as "salmonids" or "salmonoids". The family includes salmon (both Atlantic and Pacific species), trout (both ocean-going and landlocked), Salvelinus, char, Thymallus, graylings, freshwater whitefishes, taimens and lenoks, all coldwater fish, coldwater mid-trophic level, level predatory fish that inhabit the subarctic and cool temperate waters of the Northern Hemisphere. The Atlantic salmon (''Salmo salar''), whose Latin name became that of its genus ''Salmo'', is also the eponym of the family and order names. Salmonids have a relatively primitive appearance among teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back. They have slender bodies with rounded fish scale, scales and forked caudal fin, tail fins, and their fish jaw, mouths contain a si ...

Lake Istikhed
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large la ...

Chukchi Peninsula
The Chukchi Peninsula (also Chukotka Peninsula or Chukotski Peninsula; , ''Chukotskiy poluostrov'', short form , ''Chukotka''), at about 66° N 172° W, is the easternmost peninsula of Asia. Its eastern end is at Cape Dezhnev near the village of Uelen. The Chukotka Mountains are located in the central/western part of the peninsula, which is bounded by the Chukchi Sea to the north, the Bering Sea to the south, and the Bering Strait to the east, where at its easternmost point it is only about from Seward Peninsula in Alaska; this is the smallest distance between the land masses of Eurasia and North America. The peninsula is part of Chukotka Autonomous Okrug of Russia. Accessed September 2010. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chukotka Autonomous Okrug
Chukotka ( ; ), officially the Chukotka Autonomous Okrug, is the easternmost federal subjects of Russia, federal subject of Russia. It is an Autonomous okrugs of Russia, autonomous okrug situated in the Russian Far East, and shares a border with the Sakha Republic to the west, Magadan Oblast to the south-west, and Kamchatka Krai to the south, as well as a Maritime boundary, maritime border on the Bering Strait with the U.S. state of Alaska to the east.

Salvelinus
''Salvelinus'' is a genus of Salmonidae, salmonid fish often called char or charr; some species are called "trout". ''Salvelinus'' is a member of the subfamily Salmoninae within the family Salmonidae. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea. Most char may be identified by light-cream, pink, or red spots over a darker body. Scales tend to be small, with 115–200 along the lateral line. The pectoral, pelvic, anal, and the lower aspect of caudal fins are trimmed in snow white or cream leading edges. Many members of this genus are popular sport fish, and a few, such as lake trout (''S. namaycush'') and arctic char (''S. alpinus'') are objects of commercial fisheries and/or aquaculture. Occasionally such fish escape and become invasive species. Deepwater char are small species of char living below 80 m in the deep areas of certain lakes. They ar ...

Fish Of Russia
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish w ...
