What is important when you choose a home? Space, security, light – or a combination of these? Like humans, animals make choices about where to live that have important implications for their ...

Behavioural experiments in shell-dwelling cichlid fish reveal evolutionary adaptations in parents and offspring that control the timing of emergence from the nest. To mimic the empty snail shells that ...

Theoretically, competition can initiate divergence in habitat use between individuals of a species, leading to restricted gene flow and eventual speciation. Evidence that sister species differ in ...

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 ...

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 ...

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 ...

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 ...

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 ...
