Shark (Carcharhinus perezi), Cleaned by the Goby (Elacatinus randalli), at Fernando de Noronha Archipelago, Western South Atlantic

Abstract Sharks are seldom recorded as associates of reef-based cleaner fishes. Here we report on juvenile Caribbean Reef Sharks, Carcharhinus perezi, associated with Yellownose Gobies, Elacatinus randalli, off northern Brazil. The sharks sought out cleaning stations tended by the gobies and posed on the bottom while being cleaned. The bottom-resting habit of C. perezi possibly facilitates cleaning interactions with the bottom-dwelling cleaner gobies.
