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 ...

New research shows that courtship rituals evolve very fast in cichlid fish in Lake Malawi. Whenever species evolve to feed at different depths, their courtship evolves as well. In the shallows where ...

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 ...

Cuckoo catfish may be the worst parents ever. Rather than raising their own cannibalistic offspring, they force other fish species to raise them in their own mouths. But how do they do it? New ...

The spectacular radiation of 2,000 species of cichlid fishes in East Africa is an ideal model system and natural laboratory for studying evolutionary processes. The explosive speciation of cichlids is ...

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 ...

Cichlid fishes have undergone a mind-boggling degree of speciation. New research is revealing features of their genomes that primed them to diversify so spectacularly Africa's Lake Victoria is home to ...
