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 ...

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 ...

For those of you who are teased about your forgetfulness, good news! It turns out having the “memory of a fish” may actually be a compliment. Fish may have a reputation for having three-second ...
