Kurtus
''Kurtus'' is a genus of percomorph fishes, called the nurseryfishes, forehead brooders, or incubator fish, native to fresh, brackish and coastal marine waters ranging from India, through southeast Asia to New Guinea and northern Australia. ''Kurtus'' is currently the only known genus in the family Kurtidae, one of two families in the order Kurtiformes. They are famous for carrying their egg clusters on hooks protruding from the forehead (supraoccipital) of the males, although this only has been documented in ''K. gulliveri'' and available evidence strongly suggests this is not done by ''K. indicus'' (where the hook likely also is too small to carry embryos).Berra, Tim (2003).

Kurtus Indicus
''Kurtus indicus'', the Indian humphead, is a species of fish in the family Kurtidae native to fresh, brackish, and marine waters of the coastal regions of southern Asia from India to southeast China and Indonesia. It resembles the closely related '' K. gulliveri'', but is far smaller, only reaching a length of .Berra, T.B. (2003).

Freshwaters 14(4): 295-306. Although it has been suggested that the male carries the egg cluster on a hook protruding from the forehead (as known from ''K. gulliveri''), available evidence strongly suggests this is not the case in ''K. indicus'': Out of several thousand examined, none carried eggs in this manner and the male's hook is likely also too small. The female lacks the hook entirely. It is of minor importance to local commercial fisheries Commercial fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kurtus Gulliveri
''Kurtus gulliveri'', the nurseryfish, is a species of fish in the family Kurtidae native to fresh and brackish waters in southern New Guinea and northern Australia.Berra, T.B. (2003).

Freshwaters 14(4): 295-306. They can be found in estuaries, mangrove swamps, nipa swamps and slow-flowing rivers with high turbidity. This species can reach a length of , although most are far smaller: In a study of its morphology, 159 specimens were examined and the largest was , while the average was . This species is famous for its unusual breeding strategy where the male carries the egg cluster on a hook protruding from the forehead (supraoccipital). Females do not have a hook. It feeds on crustaceans (especially prawn and shrimp), small fish and insect larvae.Berra, T.B.; and Wedd, D. (2001). ''Alimen ...

Kurtiformes
The Kurtiformes consist of two extant families of ray-finned fish, the Indo-Pacific Kurtidae (consisting solely of two species in the genus '' Kurtus'') and the much more diverse and widespread Apogonidae (the cardinalfishes). The order is part of the Percomorpha clade and is regarded by many authorities as a sister taxon to the Gobiiformes. Relationships and defining characteristics A close relationship between the Kurtidae and Apogonidae was postulated based on the similarity of constituent parts of their dorsal gill arch Branchial arches, or gill arches, are a series of bony "loops" present in fish, which support the gills. As gills are the primitive condition of vertebrates, all vertebrate embryos develop pharyngeal arches, though the eventual fate of these arc ...es and that in both groups the eggs have filaments on the micropyle, which enable the eggs to form a mass.

Tokyo Sea Life Park
is a public aquarium located in Edogawa Ward, Tokyo. It is located in Kasai Rinkai Park in Edogawa Ward, Tokyo, and Kasai Rinkai Bird Garden is also located in the park. It can be accessed from Kasai-Rinkai Park Station. The Predecessor is the Ueno Aquarium, which was set up in the Ueno Zoo. The building was designed by Yoshio Taniguchi. History Tokyo Sea Life Park has its origins in "Uonozoki", the first Public aquarium in Japan that was opened in 1882. It is a public aquarium that existed only during the exposition and was closed at the end of the exposition. After that, uonozoki was demolished, but in 1929, the Ueno Aquarium was opened in the same place at Ueno Zoo. In 1952, aquariums started breeding saltwater fish based on the experimental results of filtration equipment, etc., and opened the New Ueno Aquarium in 1964. New Ueno Aquarium is one of the aquariums that started to use acrylic glass for large tanks in earnest. In 1964, acrylic panels with a height of , a width of ...

Brackish
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific grav ...

India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east.

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Marcus Elieser Bloch
Marcus Elieser Bloch (1723–1799) was a German physician and naturalist who is best known for his contribution to ichthyology through his multi-volume catalog of plates illustrating the fishes of the world. Brought up in a Hebrew-speaking Jewish family, he learned German and Latin and studied anatomy before settling in Berlin as a physician. He amassed a large natural history collection, particularly of fish specimens. He is generally considered one of the most important ichthyology, ichthyologists of the 18th century, and wrote many papers on natural history, comparative anatomy, and physiology. Life Bloch was born at Ansbach in 1723 where his father was a Torah writer and his mother owned a small shop. Educated at home in Hebrew literature he became a private tutor in Hamburg for a Jewish surgeon. Here he learned German, Latin and anatomy. He then studied medicine in Berlin and received a doctorate in 1762 from Frankfurt (Oder), Frankfort on the Oder with a treatise on skin dis ...

Fish Anatomy
Fish anatomy is the study of the form or morphology of fish. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in living fish. The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
