A team of biologists affiliated with multiple institutions in Switzerland and Tanzania has found that early cichlid diversification in Lake Victoria led to their success in deep parts of the lake. In their study, reported ...
Scientists show that the extraordinary diversity of cichlid fish in Africa's Lake Victoria was made possible by "genetic recycling"—repeated cycles of new species appearing and rapidly adapting to different roles in the ...

A pair of researchers at Central Michigan University has found that cichlid fish that brood their young in their mouths eat up to 40% of their offspring. For their paper published in the journal Biology Letters, Jake Sawecki ...
The evolution of a new species by hybridization from two already described species without a change in chromosome number is very rare in the animal kingdom. So far, only a few accepted empirical examples exist for this spontaneous ...

Cichlids ( /ˈsɪklɨd/) are fishes from the family Cichlidae in the order Perciformes. Cichlids are members of a group known as the Labroidei along with the wrasses (Labridae), damselfish (Pomacentridae), and surfperches (Embiotocidae). This family is both large and diverse. At least 1,300 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 1,300 and 3,000.
