Most fish rely primarily on their vision to find prey to feed upon, but biologists have demonstrated that a group of African cichlids feeds by using its lateral line sensory system to detect minute ...

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 ...

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 ...

About this issue Abstract Phylogenetic analyses based on mitochondrial (mt) DNA have indicated that the cichlid species flock of the Lake Victoria region is derived from a single ancestral species ...

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 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 ...

Biologists have discovered that the cichlid fish can see in the near infrared range; this was thought to be unlikely until now. Seeing in the infrared range is apparently helping fish to hunt in ...

Sex-determining systems may evolve rapidly and contribute to lineage diversification. In fact, recent work has suggested an integral role of sex chromosome evolution in models of speciation. We use ...

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 ...
