If this seems strange, remember that tuna have no arms. How else would they scratch themselves?

  Seabed, rocks etc.

    Ok but that’s far away. What’s next, not carrying all the groceries in one trip?

      That's why they risk rubbing themselves on a mincing machine. I subscribe to New Scientist (actually Dad is currently) and have done so for roughly 35 years. This is not the finest science ever reported. There will actually be loads of really great science and stuff from these studies but sadly "tuna shags shark" or some other rubbish sells ads n that. I'm starting to get a bit disillusioned now and might have to pen an "angry of Andover" piece to NS. I'll threaten to cease my subscription (that my dad pays for) and look like a right old prat. On the other hand, I might simply ask for some decent science. This isn't the best. It sounds novel to start with but rapidly looks like tosh.

  What's strange to me is that tuna even feel the urge to scratch themselves

    They can't scratch each other either....

    Apparently it's to dislodge painful parasites.
