Fig. 1 in Turtle cleaners: reef fishes foraging on epibionts of sea turtles in the tropical Southwestern Atlantic, with a summary of this association type
Fig. 1. Reef fishes cleaning sea turtles' hard and soft parts in the Southwestern Atlantic. A porkfish (Anisotremus virginicus) and a group of blue tangs (Acanthurus coeruleus) feed on epibionts on the shell of a moving hawksbill turtle (Eretmochelys imbricata); a barely visible doctorfish (Acanthurus chirurgus) nibbles at the posterior portion of the turtle's shell, and two blue tangs nibble at the left hind limb (a). Photo by M. Granville. One Zelinda's parrotfish (Scarus zelindae) and three blue tangs feed on algae growth on the shell of a male loggerhead turtle (Caretta caretta) near a shipwreck; two Spanish hogfishes (Bodianus rufus) also inspect the turtle (b). Photo by Z. Matheus. Four Spanish hogfish inspect and forage on epibionts on the shell of the same loggerhead turtle; one blue tang and one Zelinda's parrotfish also "escort" the slowly moving turtle (c). Photo by Z. Matheus. A green turtle (Chelonia mydas) remain motionless on the bottom, while a Brazilian blenny (Ophioblennius trinitatis) forages on algae growth on the left lateral portion of the shell; a few smallmouth grunts (Haemulon chrysargyreum) also capitalize upon this situation, and nibble at the turtle's shell (d). Photo by C. Sazima. A sergeant major (Abudefduf saxatilis) nibbles at an algae patch on the anterior part of the shell of a posing and hovering green turtle (e). Photo by Z. Matheus. The herbivorous Rocas damselfish (Stegastes rocasensis) nibbles at the right hind limb of a green turtle posing near algae turfs tended by this damselfish (f). Photo by Z. Matheus.
