Clownfish produce sounds to establish and defend their breeding status in social groups, but not to attract mates, according to research published November 7 in the open access journal PLOS ONE by Orphal Colleye and colleagues from the University of Liege, Belgium.
Previous studies showed that clownfish live in unique social groups, where the largest fish develops as a female, the second-largest is male, and the rest of the group remains gender neutral. If the largest fish dies, the rest of the group moves up a rank to replace the female and male.
