Cleaning interactions of fishes at Sao Tome Island, West Africa

摘要

This study reports six new types of cleaning interactions among tropical reef fish species at sao Tome Island, and confirms previously reported interactions for this area. Spicara melanurus was recorded as a cleaner for the first time, and Abudefduf saxatilis was confirmed in this role, following reports from the Southwest Atlantic. Individuals belonging to the family Labridae were the most commonly-observed cleaners, involved in over 85% of recorded interactions. Juveniles of Bodianus speciosus played a key role as cleaners, interacting with at least seven client species. In addition, some of the client fishes, including Paranthias furcifer and Acanthurus monroviae, interacted with at least four cleaner fish species. All cleaner fish species reported in this study were facultative; obligate cleaners appear to be absent from this region.
