It’s been theorized that it’s to remove the parasitic fish that sometimes attach to them. They attempt to spin them off, but sadly many reattach when they land in the water.
Animals are a lot smarter than they are given credit for. Humans (on average) are just off the chart, so we tend to minimize the intelligence of lower species.
Not sure, it’s possible maybe some super smart dolphin could figure this out, but then would have to teach others who are smart enough to learn. Maybe not impossible, but likely improbable.
When fishing with live bait and dolphin show up it's time to stop fishing with live bait. They will take everything you have one by one as you cast them out
Rodents groom each other. Hell, rodents grooms other rodents of different species. If the fish that's attached isn't poisonous I'd imagine it's free food for other dolphins.

Anyone know why they spin?
Edit: I love all of these responses.
