Shell-dwelling cichlids take intense care of their offspring, which they raise in abandoned snail shells. A team at the Max Planck Institute for Biological Intelligence used 3D-printed snail shells to ...

For conservationists, the message is clear: while community-led clean-ups are making a visible difference, protecting one of the world’s most remarkable freshwater ecosystems will ultimately require ...

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 ...

B chromosomes have a functional effect on sex determination in a species of cichlid fishes from Lake Victoria, according to a study by Japanese researchers. The researchers found sex-ratio distortions ...

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 ...

Researchers have discovered that the genes related to extracellular matrix (ECM) and the Wnt signaling pathway characterize the independently acquired lip hypertrophy in cichlids of the East African ...

The cichlids of Lake Tanganyika in Africa are highly diverse -- including with regard to sex chromosomes. These have changed extremely frequently in the course of the evolution of these fish and, ...

For those of you who are teased about your forgetfulness, good news! It turns out having the “memory of a fish” may actually be a compliment. Fish may have a reputation for having three-second ...

A Case Western Reserve University scientist has played the lead role in identifying an invasive species related to one already threatening other fish in the waters of the southern United States. That ...

Scientists have uncovered evidence of fish mating with species different from their own—a process that can lead to the creation of several new species. For a study published in the journal Nature ...
