Cichlids are one of the largest and strangest groups of vertebrate fish — fish with backbones — on Earth. They’re popular as pets and farmed in aquaculture, and scientists have been studying them ...

Arecent phylogeographical examination of east African river cichlid fish species has pinpointed the area of speciation to a now extinct lake in Botswana. The turbid rivers of Africa typically contain ...

Cannibalism, the eating of conspecifics, has a rational background in the animal kingdom. It may serve as a source of energy-rich nutrition or to increase reproductive success. Some species do not ...

Scientists have discovered that a pair of closely related species of East African cichlid fishes -- a group of fish whose diversity comprising hundreds of species has puzzled evolutionary biologists ...

Lake Tanganyika in Africa is a true hotspot of organismal diversity. Approximately 240 species of cichlid fishes have evolved in this lake in less than 10 million years. A research team from the ...

In an effort to understand the molecular basis of adaptation in vertebrates, researchers sequenced the genomes and transcriptomes of five species of African cichlid fishes. A research team uncovered a ...
