Cichlid fishes are celebrated for their vast taxonomic, phenotypic, and ecological diversity; however, a central aspect of their evolution — the timeline of their diversification — remains contentious ...

Different beak and jaw shapes are illustrative examples of how animal species have adapted to different food sources. In a new study published in the journal Nature, researchers now show how diet ...

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 ...

The biological family Cichlidaea is one of the most fascinating examples of animal evolution on Earth. Convict cichlids are a widespread, well-known species within this unique group. Convict cichlids ...

Cichlid fishes have undergone a mind-boggling degree of speciation. New research is revealing features of their genomes that primed them to diversify so spectacularly Africa's Lake Victoria is home to ...

East Africa’s Lake Victoria is home to over 500 species of cichlid, and according to scientists, that amount of diversity is a recent development. With the lake only filling with water some 16,000, ...

Cichlid fishes are an important evolutionary model (Kocher, 2004). Their uncanny ability to exploit new environments by radiating into a wide array of shapes and forms has made them an ideal system to ...

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.

Cichlids are a striking type of freshwater fish with over 500 species. They're usually found in warmer regions and in various bodies of water, including ponds, rivers, lakes, and streams. Most species ...

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 ...

The researchers analyzed extensive genome and transcriptome data of around 240 cichlid species for differences between females and males, which enabled them to identify sex chromosomes in over 70 ...

Cichlid fish are seen sucking up sand and spitting it out in a pile to impress females and intimidate rivals with their 'sandcastles'. The mounds of sand, called bowers, are each subtly different in ...
