They're not. It's vice versa.

shark are scared of dolphin.
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.
They aren't any relationship between them as sharks eat dolphins.

dolphins enemies are bull sharks tiger sharks dusky sharks and great white sharks.sharks can kill dolphins.
Dolphins VS sharks, hmmm. Sharks are pretty strong but dolphins are better. Sharks have pretty sharp teeths but dolphins are much more smarter faster and can kill sharks by smashing their strong beaks right into the sharks gills. Sharks can swim ten to twenty miles per hour but dolphins can swim up to thirty miles per hour, let's go for the dolphins. Sharks has sharp teeths but dolphins has a really strong beak that can kill sharks. The dolphins is now the winner.
Yes, of course dangerous animals can come on shore. Sharks, stingrays, killer dolphins, and jelly fish.
