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 ...

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 ...

Scientists at the Shedd Aquarium have been successful in breeding a previously undiscovered species of fish that might help save Africa`s largest lake, Shedd officials announced last week. The fish ...

Researchers have found that male African cichlids vocalize during courtship, and that females' sensitivity to these sounds increases when they are ready to mate. African cichlids enjoy an alien, ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 105, No. 40 (Oct. 7, 2008), pp. 15475-15480 (6 pages) The existence of ancient deep-water lakes provides an ...

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 ...

Beau Alward, University of Houston assistant professor of psychology, who holds a joint appointment in biology and biochemistry and is director of the Social Neuroscience Lab, has received the Beckman ...

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 ...

The African cichlid fish radiations are the most diverse extant animal radiations and provide a unique system to test predictions of speciation and adaptive radiation theory. The past few years have ...
