What do remoras do turtles?
Some cultures use remoras to catch turtles. A cord or rope is fastened to the remora’s tail, and when a turtle is sighted, the fish is released from the boat; it usually heads directly for the turtle and fastens itself to the turtle’s shell, and then both remora and turtle are hauled in.
In such symbiotic relationship, remoras remove the parasites (such as copepods) found on the host turtle and clean sloughing epidermal tissue as well as ingesting scraps of food, feces, and small nekton and zooplankton.
