Crittercam on Gulf of California Green Turtles III: Stationary Benthic Foraging Gigartina

Sitting still on the sea floor to consume red algae seems like the most energetically efficient diet intake strategy. However the interaction, or at least association, with other species during foraging is a new insight provided by the Crittercam footage. Note in this video that the turtle expels algae fragments from its mouth as it forages. We don’t see the Cortez Angelfishes (Pomacanthus zonipectus) consuming these fragments, but this may be why they are attracted to this turtle.
