The spectacular radiation of 2,000 species of cichlid fishes in East Africa is an ideal model system and natural laboratory for studying evolutionary processes. The explosive speciation of cichlids is ...

Figure 1: The egg-spots of haplochromine cichlids. Figure 2: The role of fhl2a and fhl2b in egg-spot formation. Figure 3: Gene tree of the two fhl2 paralogs and expression profiling in East African ...

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 ...

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 ...

Mouthbrooding fish under stress may sometimes resort to cannibalism and eat their young. Scientists' discovery of the behavior was "a complete accident." When you purchase through links on our site, ...

This study tested if convict cichlids (Amatitlania siquia) with prior predator experience could socially transfer their predator knowledge to their offspring. Prior to reproduction, pairs were ...

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 ...

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 ...

Dubai’s indoor rainforest opens new aquarium with 2,000 African cichlid fish Starting June 22, guests can dive into the world's largest freshwater cichlid aquarium for the ‘Snorkel with Cichlid’ ...

In South Florida’s tropical climate, many exotic fish species are right at home in local ponds, lakes and canals. Mayan cichlids and oscars are two of the more abundant non-native species. Both are ...
