Phylogenetic relationships and evolution of cleaning behaviour in the family Labridae: importance of body colour pattern.

Résumé

The family Labridae contains numerous fishes known to act as cleaners in the wild. Previous studies suggested that a small body size and specific colour patterns may be prerequisites for cleaning. We investigated whether cleaning behaviour is linked to particular fish phenotypes. We first present a phylogeny based on partial 12S rRNA gene sequences of 32 wrasses sampled from different localities in the Indo-Pacific and Atlantic oceans, and in the Mediterranean Sea. Secondly, descriptive data (fish body size, fish body shape and fish body colour patterns) were analyzed in a phylogenetic context using comparative methods. We found no relationship between fish cleaning behaviour and fish body size and shape, but instead a correlation between cleaning behaviour and the presence of a dark lateral stripe within wrasses. Our results suggest that the evolution of cleaning depends upon the presence of a dark median lateral stripe on the fish body surface.
