when people capture sharks they cut off their fins and then release them back into the water for dead because sharks can't swim without fins so they sink to the bottom of the ocean to drown because they have to come up for some air sometime but can't without fins

no sharks do not hurt themselves with their own teeth because they don't close their mouth fully and the teeth do not touch them

A dolphin can hurt a shark it just depends on the shark its attacking. Dolphins are pretty smart when choosing who to pick on. They have been known to gang up on certain species of sharks, but generally only those that are not dangerous to them. Dolphins tend to leave the more dangerous sharks (such as Tiger sharks) alone.

Dolphins of any kind have never been known to hurt humans. There are actually recorded cases of them protecting humans from sharks.
