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.

Neogobius Fluviatilis
''Neogobius'' is a genus of goby native to Black Sea and the Caspian Sea basins. It is part of the broader Benthophilinae subfamily which is also endemic to the same region. Nevertheless, two ''Neogobius'' species have recently turned out to be highly invasive and spread across Europe and even to the Great Lakes of North America. Species There are currently four recognized species in this genus: * '' Neogobius caspius'' ( Eichwald, 1831) (Caspian goby) * ''Neogobius fluviatilis'' (Pallas, 1814) (Monkey goby) * ''Neogobius melanostomus'' (Pallas, 1814) (Round goby) * '' Neogobius pallasi'' (Berg Berg may refer to: People *Berg (surname), a surname (including a list of people with the name) *Berg Ng (born 1960), Hong Kong actor * Berg (footballer) (born 1989), Brazilian footballer Former states *Berg (state), county and duchy of the Holy ..., 1916) (Caspian sand goby) Of these, ''N. bathybius'', ''N. caspius'' and ''N. pallasi'' are endemic to the Caspian basin.

Ponticola Kessleri
''Ponticola kessleri'', the bighead goby or Kessler's goby, is a species of goby native to Eurasia. The bighead goby is a Ponto-Caspian relict species. It inhabits the fresh and oligohaline waters, with mineralisation from 0-0.5‰ up to 1.5-3.0‰. Characteristics This species has a big flattened head, strongly expended upper lip, prolonged-conical body and thickened anterior. The mandibula is longer than maxilla. It reaches . A triangular dark spot is visible near the caudal fin. The collar of its abdominal sucker has blades. The sucker does not reach the anus. It is red- or grey-brown with 5 transverse lines on the back, one of which is on the basis of the caudal fin. The head has light round spots with a white margin on sides. The basis of the pectoral fin has wave-shaped brown spots, odd fins have lines of black spots. This species is distinguished from related Black Sea basin inhabitants by the following: 75-95% of its length is between its origin and anus; ctenoid scales ...

Mesogobius Batrachocephalus
''Mesogobius batrachocephalus'', the knout goby or toad goby, is one of the species of gobiid fish native to the Black Sea and the Sea of Azov basins. It lives in estuaries and brackish water lagoons, occasionally in fresh waters, such as the coastal Lake Siutghiol in Romania. It prefers areas near cliffs with sandy, shelly or rocky substrates at depths of from , sometimes down to . The knout goby is a piscivore A piscivore () is a carnivorous animal that eats primarily fish. The name ''piscivore'' is derived . Piscivore is equivalent to the Greek-derived word ichthyophage, both of which mean "fish eater". Fish were the diet of early tetrapod evoluti .... It can reach a length of SL and weight of .

Goby
Goby is a common name for many species of small to medium sized ray-finned fish, normally with large heads and tapered bodies, which are found in marine, brackish and freshwater environments. Traditionally most of the species called gobies have been classified in the order Perciformes as the suborder Gobioidei but in the 5th Edition of ''Fishes of the World'' this suborder is elevated to an order Gobiiformes within the clade Percomorpha. Not all the species in the Gobiiformes are referred to as gobies and the "true gobies" are placed in the family Gobiidae, while other species referred to as gobies have been placed in the Oxudercidae. Goby is also used to describe some species which are not classified within the order Gobiiformes, such as the engineer goby or convict blenny ''Pholidichthys leucotaenia''. The word goby derives from the Latin ''gobius'' meaning "gudgeon", and some species of goby, especially the sleeper gobies in the family Eleotridae and some of the dartfishes are ...

Cobitis Taenia
The spined loach (''Cobitis taenia'') is a common freshwater fish in Europe. It is sometimes known as spotted weather loach, not to be confused with the "typical" weather loaches of the genus ''Misgurnus''. This is the type species of the spiny loach genus ('' Cobitis'') and the true loach family (Cobitidae). Description The spined loach typically reaches an adult length of , although females may grow up to . Adults weigh between . Their backs feature a yellow-brown colouring interspersed with many small grey or brown scales on the spinal ridge. The scales on the belly are pale yellow or orange. The body overall is long and thin. There are 6 barbels around the mouth. Under the eyes there is a two-pointed spike, with which the fish can inflict a painful sting. Distribution and relationships It is found from the Volga River basin to France. Generally it occurs across much of temperate Europe north of the Alpide belt, with the exceptions of Ireland, Scotland, Wales and northern ...

Dikerogammarus Haemobaphes
''Dikerogammarus haemobaphes'' is a species of freshwater gammarid crustacean. These gammarids are commonly known as demon shrimp, likely because they are an extremely successful invasive species. Native to the Ponto Caspian basin, ''Dikerogammarus haemobaphes'' expanded their range in 1955. This expansion began in Lake Balaton, Hungary and then spread into certain rivers and lakes in Austria, Belgium, Germany, Poland, Russia, Ukraine, and the United Kingdom. These crustaceans likely broadened their range due to the interconnection of waterways in Europe and the use of transportation vectors such as boats and ships. Identification ''Dikerogammarus haemobaphes'' have a semi-transparent, white body consisting of a head, thorax, and abdomen. Their body consists of seven segments, each with a pair of pereopods (walking legs). These shrimp are different from other gammarid species as their peduncle, flagellum of antennae, and gnathopods have short bristles rather than long o ...

Dikerogammarus Villosus
''Dikerogammarus villosus'', also known as the killer shrimp, is a species of amphipod crustacean native to the Ponto-Caspian region of eastern Europe, but which has become invasive across the western part of the continent. In the areas it has invaded, it lives in a wide range of habitats and will prey on many other animals. It is fast-growing, reaching sexual maturity in 4–8 weeks. As it has moved through Europe, it threatens other species and has already displaced both native amphipods and previous invaders. Description ''D. villosus'' can grow up to in length, relatively large for a freshwater amphipod. It varies in appearance, with some specimens being striped, and some not. It has relatively large mandibles which allow it to be an effective predator. Distribution ''D. villosus'' was originally found in the lower courses of large rivers in the Black Sea and Caspian Sea drainage basins. It has become an invasive species across central and western Europe, using the Dan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
