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 ...

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 ...

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.

The analysis of fossils in sediment cores from Lake Victoria, Africa, reveals that a group of cichlid fish rapidly diversified as the lake got larger and provided new ecological niches, whereas the ...

It all started with the Convict cichlids. The small striped fish, native of Central America, captured Sac State Biology Professor Ron Coleman’s attention in a laboratory at the University of Toronto ...

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 ...

The unique diversity of cichlids in Africa’s oldest lake could help unlock the secrets of evolution. Baby Haplotaxodon microlepis scramble for safety in their mother’s mouth. Like many cichlid species ...

Cichlids are one of the largest and strangest groups of vertebrate fish — fish with backbones — on Earth. They’re popular as pets and farmed in aquaculture, and scientists have been studying them ...

The poster child for evolution may have finally revealed its secret. More than 1000 closely related but different species of cichlid fish live in Lake Malawi in south-east Africa – more than in any ...

Some female fish have eyes for their man only. Colourful African cichlids have evolved into new species because females are partially blind to others. But even as that discovery is made, the species ...
