Dimidiochromis
''Dimidiochromis'' is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. All of its species are elongated in shape and predatory on smaller fishes.

Dimidiochromis Compressiceps
The Malawi eyebiter (''Dimidiochromis compressiceps'') is a species of fish in the family Cichlidae. This predatory cichlid is endemic to Lake Malawi in East Africa. Description ''Dimidiochromis compressiceps'' can reach a length of about . The females are considerably smaller than males. The body is narrow and laterally compressed (hence the Latin name ''compressiceps'') minimizing its visibility. The mouth is quite large and jaws are relatively long, reaching about one-third of the body length. This large and impressive cichlid normally shows a whitish-silver body with a brown horizontal stripe along the sides, from the snout to the tail. Sexually mature males put on a dazzling metallic blue with reds and oranges on their fins.Marc EliesoDimidiochromis compressiceps in Cichlid Forum/ref> Behavior This species once was regarded as a specialist, feeding on eyes of other fishes (hence the common name ''eyebiter''), (Winkler, 1966) but such behavior has never been observed in the w ...

Dimidiochromis Strigatus
''Dimidiochromis strigatus'' is a species of haplochromine cichlid endemic to Malawi. It was formerly placed in the genus '' Haplochromis'' and known as ''Haplochromis'' 'sunset' in the aquarium fish trade. It is endemic to Malawi where it is found in Lake Malawi, Lake Malombe and the upper and mid Shire River. It is normally found in shallower areas with a mixture of weedy and sandy habitats. It is a predator of small fishes such as utaka and larger invertebrates.

Dimidiochromis Kiwinge
''Dimidiochromis kiwinge'' is a species of haplochromine cichlid which is found in Lake Malawi and Lake Malombe in Malawi, Mozambique, and Tanzania. Its natural habitat is freshwater lakes. This species is normally found in the vicinity of rocks, although it frequently forms offshore shoals and is a common predator on the surface near the shore where it feeds on small fishes, especially utaka and Lake Malawi sardines. It either hunts in pairs or in large groups. The females are mouthbrooders and while they are brooding young they remain in midwater until the fry are released.

Cichlid Genera
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquar ...

Haplochromine
__NOTOC__ The haplochromine cichlids are a tribe of cichlids in subfamily Pseudocrenilabrinae called Haplochromini. This group includes the type genus (''Haplochromis'') plus a number of closely related genera such as '' Aulonocara'', '' Astatotilapia'', and '' Chilotilapia''. They are endemic to eastern, southern and northern Africa, except for ''Astatotilapia flaviijosephi'' in the ''Middle East''. A common name in a scientific context is East African cichlids – while they are not restricted to that region, they are the dominant Cichlidae there. This tribe was extensively studied by Ethelwynn Trewavas, who made major reviews in 1935 and 1989, at the beginning and at the end of her career in ichthyology. Even today, numerous new species are being described each year. The haplochromines were in older times treated as subfamily Haplochrominae, However, the great African radiation of pseudocrenilabrine cichlids is certainly not monophyletic without them, and thus they are t ...

Lake Malawi
Lake Malawi, also known as Lake Nyasa in Tanzania and Lago Niassa in Mozambique, is an African Great Lake and the southernmost lake in the East African Rift system, located between Malawi, Mozambique and Tanzania. It is the fifth largest fresh water lake in the world by volume, the ninth largest lake in the world by area—and the third largest and second deepest lake in Africa. Lake Malawi is home to more species of fish than any other lake in the world, including at least 700 species of cichlids.Turner, Seehausen, Knight, Allender, and Robinson (2001). "How many species of cichlid fishes are there in African lakes?" ''Molecular Ecology'' 10: 793–806.

East Africa
East Africa, Eastern Africa, or East of Africa, is the eastern subregion of the African continent. In the United Nations Statistics Division scheme of geographic regions, 10-11-(16*) territories make up Eastern Africa: Due to the historical Omani Empire and colonial territories of the British East Africa Protectorate and German East Africa, the term ''East Africa'' is often (especially in the English language) used to specifically refer to the area now comprising the three countries of Kenya, Tanzania, and Uganda. However, this has never been the convention in many other languages, where the term generally had a wider, strictly geographic context and therefore typically included Djibouti, Eritrea, Ethiopia, and Somalia.Somaliland is not included in the United Nations geoscheme, as it is internationally recognized as a part of Somalia. *Tanzania, Kenya, Uganda, Rwanda, Burundi, Democratic Republic of Congo and South Sudan are members of the East African Community.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predatory
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate an ...
