Hidden within fish DNA are powerful genetic twists that may explain one of nature’s biggest mysteries: how new species form so quickly. In Lake Malawi, hundreds of cichlid fish species evolved at ...

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 ...

Scientists show the extraordinary diversity of cichlid fish in Africa’s Lake Victoria was made possible by ‘genetic recycling’ - repeated cycles of new species appearing and rapidly adapting to ...

The cichlids of Lake Tanganyika in Africa are highly diverse -- including with regard to sex chromosomes. These have changed extremely frequently in the course of the evolution of these fish and, ...

Raising babies can be exhausting—so much so that some mouthbrooding mothers snack on their young, according to a new study. A central African cichlid fish, Astatotilapia burtoni—commonly called Burton ...
