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 ...

Scuba divers found some “large”-eyed lake creatures off the coast of Malawi and discovered two new species, a study said and photos show. Photo from Getty / iStockphoto Plunging into a large lake in ...

Researchers have found that chunks of "flipped" DNA can help fish quickly adapt to new habitats and evolve into new species, acting as evolutionary "superchargers." In the face of threats from other ...

Biologists have genetically mapped the sex chromosomes of several species of cichlid fish from Lake Malawi, East Africa, and identified a mechanism by which new sex chromosomes may evolve. In research ...

Most fish rely primarily on their vision to find prey to feed upon, but a University of Rhode Island biologist and her colleagues have demonstrated that a group of African cichlids feeds by using its ...

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 ...

Gene transfer inhibition in the African cichlids fish might explain the evolution of new species, a study in Nature Ecology & Evolution, has found. Martin Genner, a professor of Ecology, Population ...
