Cichlids can be protective parents or infanticidal cannibals—studying these extremes could provide new insights into their ...

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 ...

In bony fish the swim bladder primarily serves for buoyancy. Moreover, in many species it also possesses acoustic functions: it plays a role in sound production and improves hearing in numerous ways.

In the April issue of Scientific American, I present recent insights into the extraordinary evolution of cichlid fish. Although many factors have probably contributed to the stunning success of this ...

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 ...

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

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 ...

Aristos is a Newsweek science and health reporter with the London, U.K., bureau. He is particularly focused on archaeology and paleontology, although he has covered a wide variety of topics ranging ...

The communication of aggressive propensity is an important component of agonistic interactions. For this purpose, animals use different sensory modalities involving visual, acoustical and chemical ...

Raising babies can be exhausting—so much so that some mouthbrooding mothers snack on their young, according to a new study. A central African cichlid fish, Astatotilapia burtoni—commonly called Burton ...
