Siniperca Kawamebari
''Coreoperca kawamebari'', commonly known as the Japanese perch, redfin perch, Japanese river perch, Eye-spot perch or in Anglophone parts of Japan, simply the perch, is a predatory species of the freshwater perch native to Japan and southern Korea. They are sometimes kept as pets. The Japanese perch (Coreoperca kawamebari) are a member of the perch family but with the predatory feeding behaviour of the black bass (Micropterus) and bluegill (Lepomis macrochirus). Description Japanese perch are greenish with red pelvic, anal and caudal fins. They have five to eight dark vertical bars on their sides. The Japanese perch can reach up to in length. They can live for up to 7 years. Diet The Japanese perch is a predatory species. Juveniles feed on zooplankton, bottom invertebrate fauna, other fish fry, scuds, small shrimp and insects, while adults feed on both invertebrates and smaller fish, mainly Japanese rice fish, Japanese minnows (Nipponocypris temminckii, Rhynchocypris, Gn ...

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch people, Dutch Aristocracy (class), aristocrat, Zoology, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna japonica'' (1844–1850).

Freshwater Fish Of Japan
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is ...

Fish Of Japan
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Vallisneria
''Vallisneria'' (named in honor of Antonio Vallisneri) is a genus of freshwater aquatic plant, commonly called eelgrass, tape grass or vallis. The genus is widely distributed in tropical and subtropical regions of Asia, Africa, Europe, and North America. ''Vallisneria'' is a submerged plant that spreads by runners and sometimes forms tall underwater meadows. Leaves arise in clusters from their roots. The leaves have rounded tips, and definite raised veins. Single white female flowers grow to the water surface on very long stalks. Male flowers grow on short stalks, become detached, and float to the surface. It is dioecious, with male and female flowers on separate plants. The fruit is a banana-like capsule having many tiny seeds. Sometimes it is confused with the superficially similar ''Sagittaria'' when grown submerged. This plant should not be confused with ''Zostera'' species, marine seagrasses that are usually also given the common name "eelgrass". ''Vallisneria'' has arche ...

Common Kingfisher
The common kingfisher (''Alcedo atthis''), also known as the Eurasian kingfisher and river kingfisher, is a small kingfisher with seven subspecies recognized within its wide distribution across Eurasia and North Africa. It is resident in much of its range, but migrates from areas where rivers freeze in winter. This sparrow-sized bird has the typical short-tailed, large-headed kingfisher profile; it has blue upperparts, orange underparts and a long bill. It feeds mainly on fish, caught by diving, and has special visual adaptations to enable it to see prey under water. The glossy white eggs are laid in a nest at the end of a burrow in a riverbank. Taxonomy The common kingfisher was first described by Carl Linnaeus in the 10th edition of his ''Systema Naturae'' in 1758 as ''Gracula atthis''. The modern binomial name derives from the Latin ', 'kingfisher' (from Greek , '), and ''Atthis'', a beautiful young woman of Lesbos, and favourite of Sappho. The genus ''Alcedo'' comprises ...

Great Cormorant
The great cormorant (''Phalacrocorax carbo''), known as the black shag in New Zealand and formerly also known as the great black cormorant across the Northern Hemisphere, the black cormorant in Australia, and the large cormorant in India, is a widespread member of the cormorant family of seabirds. The genus name is Latinised Ancient Greek, from φαλακρός (''phalakros'', "bald") and κόραξ (''korax'', "raven"), and ''carbo'' is Latin for "charcoal". It breeds in much of the Old World, Australia, and the Atlantic Ocean, Atlantic coast of North America. Taxonomy and etymology The long white-breasted cormorant ''P. c. lucidus'' found in sub-Saharan Africa, has a white neck and breast. It is often treated as a full species, ''Phalacrocorax lucidus'' (e.g. , ). In addition to the Australasian and African forms, ''Phalacrocorax carbo novaehollandiae'' and ''P. c. lucidus'' mentioned above, other geographically distinct subspecies are recognised, including ''P. c. sinensis' ...

Spawn (biology)
Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and marine reptile, reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing Ovum, ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mos ...

Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

Crayfish
Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as ''Procambarus clarkii'', are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus. The term "crayfish" is applied to saltwater species in some countries. Terminology The name "crayfish" comes from the Old French word ' (Modern French '). The word has been modified to "crayfish" by association with "fish" (folk etymology). The largely American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypomesus Nipponensis
''Hypomesus nipponensis'' (Japanese smelt, in Japanese: ''wakasagi'') is a commercial food fish native to the lakes and estuaries of northern Honshu and Hokkaido, Japan, Korea, and Sakhalin, Khabarovsk Krai, and Primorsky Krai, Ruassia. It has been introduced in other locations, including the San Francisco Delta of the United States. It is raised in fisheries, and is very similar in appearance to the delta smelt (''H. transpacificus''). Synonyms ''Hypomesus chishimaensis'' was described as being a new species in the lakes of Kunashir and Iturup in 1997 based on claimed morphological differences. After later studies failed to find these morphological differences, it regarded as an ecotype of ''H. nipponensis''. A 2007 genetic analysis supported this classification, and recommended that ''H. chishimaensis'' not be given its own binomial designation.
