Kurtidae
''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 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). ''Nurseryfish, Kurtus gulliveri (Perciformes: Kurtidae), from northern Australia: redescription, distribution, egg mass, and comparison with K. indicus from southeast Asia.'' Ichthyol. Explor. Freshwaters 14(4): 295-306. 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).

Kurtiformes
The Apogonoidei is a suborder of Gobiiformes, gobiiform fish consisting of two families: 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, based on phylogenetic evidence, is considered a sister taxon to the Gobioidei, gobies and Trichonotus, sand divers. In some older treatments, it is instead treated as its own order, Kurtiformes (). Relationships and defining characteristics A close relationship between the Kurtidae and Apogonidae was postulated based on the similarity of constituent parts of their dorsal fish anatomy, gill arches and that in both groups the eggs have filaments on the Micropyle (zoology), micropyle, which enable the eggs to form a mass. This mass is brooded in the mouth in the Apogonidae and borne on the supraoccipital hook of at least one of the two nursery fishes in the Kurtidae. They also have horizontal ...

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, 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 (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

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 can be 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 spec ...

New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; , fossilized , also known as Papua or historically ) is the List of islands by area, world's second-largest island, with an area of . Located in Melanesia in the southwestern Pacific Ocean, the island is separated from Mainland Australia, Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf, and were united during episodes of low sea level in the Pleistocene glaciations as the combined landmass of Sahul. Numerous smaller islands are located to the west and east. The island's name was given by Spanish explorer Yñigo Ortiz de Retez during his maritime expedition of 1545 due to the perceived resemblance of the indigenous peoples of the island to those in the Guinea (region), African region of Guinea. The eastern half of the island is the major land mass of the nation of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Pap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order (biology)
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and 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. For some groups of organisms, their orders may follow consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 Frankfort on the Oder with a treatise on skin disorders. He then became a ...

Fish Anatomy
Fish anatomy is the study of the form or Morphology (biology), 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 density, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
