Green sea turtle with some marks on the shell

Here's a turtle photographed in Hawaii. What do you think the marks on its shell are?

Marks left by a parasite cleaner, Wrasse type?

I thought they looked like 'normal' markings.

Scratches from rocks / other turtles / sharks?

I Googled a few images and most animals do show the marks. Hard to say if they are natural or acquired as the result of interaction with something else?

Thank you, all.
I meant the black scratches on the back. These are not normal scratches. No parasite cleaners could have left them either (they are too small for that). Scratches from rocks? Maybe, but there are many rocks and turtles like to feed next to them in the surf. Why only this one has the marks? I saw many turtles, but never the one with such marks. A shark? I thought about it, but a shark expert said it was doubtful.
