Welcome to r/science! This is a heavily moderated subreddit in order to keep the discussion on science. However, we recognize that many people want to discuss how they feel the research relates to their own personal lives, so to give people a space to do that, personal anecdotes are now allowed as responses to this comment. Any anecdotal comments elsewhere in the discussion will continue to be removed and our normal comment rules still apply to other comments.

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.

Just wanted to say that the shark in the picture looks so dam happy and cute.

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?
