Brood parasitism in fish [Phys]

par Frédéric Magné - publié le

Professor Axel Meyer, an evolutionary biologist from the University of Konstanz, and a team of researchers from the Institute of Vertebrate Biology in Brno (Czech Republic) have carried out research into the evolutionary strategies employed by cuckoo catfish and various types of cichlids that occur in Lake Tanganyika and several other African lakes. Their study paints a fascinating picture of evolutionarily shaped and individually learned defence behaviour, as well as the deception efforts employed by both species of fish—and the high price that cichlids pay for keeping the illegitimate offspring of the cuckoo catfish away from their own eggs.
