The open ocean is a good place for parasites, fish don't have arms to remove them and swim far from anything fixed like a coral reef that can be used as a comb.

A team of researchers has found that fish like to rub against sharks to scratch themselves and remove irritants including parasites. They prefer sharks to other fish for this purpose. Shark skin is rough, made up of tiny tooth like structures, and was used as sand paper in prehistoric times.

true. shark skin is abrasive and coarse, like sand paper (not the fine grit ones). no wonder other fish use this predator to scrape off their ectoparasites. the fish help each other out.

I love sharks. I don’t care what anybody says, I think they’re magnificent, beautiful creatures.

Does this have a negative impact on sharks by transferring parasites to them?
