cichlid

(sĭk`lĭd), common name for members of the family Cichlidae, several hundred species of spiny-finned freshwater fishes of moderate or small size, native to Africa, S Asia, Mexico, and Central and South America. Cichlids are found in tropical waters. The larger species are food fish of some importance, and small species are popular as aquarium fish. Cichlids are noted for the care they give their young; the eggs are laid in a basin hollowed in the sand and, until they hatch, are stored in the mouth of either the male or the female, depending on the species. Cichlids are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

Cichlid

(graphics, tool)
A tool for rapidly visualising arbitrary data in high-quality 3D, while allowing the viewer to explore and interact with the data in real time. Cichlid was designed with remote data generation and machine independence in mind; data is transmitted via TCP from any number of sources (data servers) to the visualisation code (the client), which displays them concurrently.

Further sampling and analyses of morphological, meristic, genetic and ecological differentiation from the syntopic Midas cichlid species warranted a species description.
Brian Zimmerman, curator of the aquarium at the zoo, said: "The Mangarahara cichlid is shockingly and devastatingly facing extinction; its wild habitat no longer exists and as far as we can tell, only three males remain of this entire species.
Most studies of agonistic behavior have focused on aggressive interactions between males; however, female-female contests are also observed in some taxa, for example in cichlids (Draud et al.
Feeding strategies of cichlids are diverse and highly adapted to exploit a variety of niches (Fryer and |les 1972; Maitipe and De Silva, 1985: Bowen and Allanson 1982).
This leaves one fish to protect the eggs from other cichlid species.
This is the first record of this non-native cichlid from natural freshwater bodies of Iran (Golabi spring), the second record from the Middle East and the only record where the species is extant in the wild in the Middle East.
These cichlids are unusual because they form permanent hierarchical social groups made up of a dominant breeding pair and many helpers that look after the young and defend their territory.
Some cichlid fish see red better while others only have eyes for blue.
In particular, extensive within-habitat proliferation, and repeated evolution of similar ecomorphs in different habitats has been found in cichlid fish in the Great African Lakes (Ruber et al.
