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, led by University of Bristol, have been studying a fish sensory organ to understand cues for collective behavior which could be employed on underwater robots. Why would having two sets of ...

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 ...

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 ...

African cichlids are among the most interesting fish in the freshwater hobby for many reasons, but mouthbrooding is near the top of the list - a survival strategy so effective that it looks alarming ...

Complex teeth with multiple cusps in an African cichlid fish. The cichlid fish of Africa's Great Lakes have formed new species more rapidly than any other group of vertebrates. A new study shows that ...

Biologists from the University of Bonn have discovered that the cichlid fish Pelvicachromis taeniatus can see in the near infrared range; this was thought to be unlikely until now. Seeing in the ...

African cichlid fish evolved in calm, clearwater lakes saturated with sunlight, and are known for their incredible visual system, which relies on a diverse array of visual pigment proteins called ...
