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 ...

Fish viewed digital models with unfamiliar fish faces longer and from a further distance than models with familiar faces, according to a new study. Fish viewed digital models with unfamiliar fish ...

Caring for children can be a tough job, particularly if you are a female cichlid fish, with research showing that male cichlid fish have a propensity to desert their mates, leaving them to then look ...

In social fish like cichlids, status is everything. High-status males are territorial and colorful – they defend territories and reproduce with females. Low-status males, which are less colorful and ...

Cichlid fishes, renowned for their extraordinary speciation and adaptive radiation, provide an exceptional framework to explore evolutionary dynamics, particularly through the study of their parasites ...

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 ...

What is important when you choose a home? Space, security, light – or a combination of these? Like humans, animals make choices about where to live that have important implications for their ...

Two discrete cichlid fishes endemic to Cuatro Ciénegas, Mexico differ significantly in several morphological characters associated with feeding specializations. Conventional taxonomic treatment would ...

Scientists have uncovered evidence of fish mating with species different from their own—a process that can lead to the creation of several new species. For a study published in the journal Nature ...

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 ...
