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 ...

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.

There are concerned, overprotective parents, and then there are cichlid fish. After a male cichlid fertilizes the female’s eggs, she holds her entire brood of embryos inside her mouth for two weeks ...

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’ ...

"Sound vibrations are transmitted to the inner ear via anterior extensions of the swim bladder or via bony ossicles", the biologist Tanja Schulz-Mirbach explains how swim bladders may serve for ...

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 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 ...
