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 ...

Evolutionary biologists describe a new gene in the Central American Midas cichlid fish and identify a variant caused by a 'jumping gene' (transposon). This variant of the 'goldentouch gene' is most ...

Africa's Lake Victoria is home to one of evolution's greatest experiments. In its waters, what began as a single lineage belonging to the cichlid family of fishes has since given rise to a dazzling ...

The biological family Cichlidaea is one of the most fascinating examples of animal evolution on Earth. Convict cichlids are a widespread, well-known species within this unique group. Convict cichlids ...

Breeding and examining the cichlids with and without stripes in the laboratory shows that all cichlids carry the "stripes gene," but the switches (regulatory elements) of this gene differ. "This ...

We associate nests with shelter, warmth, and a safe retreat—and usually picture a bird's nest made out of twigs, grass and feathers. Yet many other animals take advantage of such refuges, with nests ...

A new study that looked at gut length variation between cichlid fish species found that some of the genetic loci for the trait are sex-specific even though males and females of the same species have ...
