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 cichlid fishes of Lake Malawi are famously diverse. However, phylogenetic and population genetic studies of their history have been difficult because of the great amount of genetic variation that ...

Animals are remarkably diverse in their sleep and activity patterns due to foraging strategies, social behavior and their desire to avoid predators. With more than 3,000 types of cichlids, these ...

Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers. This trait influences the cichlids' ability to adapt to new habitats. The ...

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 ...

One decision in the 1950s transformed Lake Victoria’s ecosystem. The Nile perch was introduced into Lake Victoria in Africa in an effort to boost commercial fishing by creating larger catches for the ...

Cichlid fishes are one of the best model system for the study of evolution of the species. Inspired by them, in this paper we simulated the splitting of a single species into two separate ones via ...

Animals are remarkably diverse in their sleep and activity patterns due to foraging strategies, social behavior and their desire to avoid predators. With more than 3,000 types of cichlids, these ...
