No, because dolphins have sex for fun!
The size of a dolphin compared to a shark is more than half and dolphins aren't predators. If you compare more factors, a dolphin could never win
well since a group of dolphins can kill a shark then maybe a shark is dumber than a dolphin.
A whale shark is much larger than any dolphin but it only eats very small fish and krill because it has no teeth (edit that if i am wrong).
OF COURSE whales are the biggest living animal in the ocean
it mainly depends on the circumstances. If the dolphin is alone, and trys to fight the shark, it will be killed. But if it was a pod of dolphins, the dolphins would have the upper hand. But as for your question, if the shark got into a fight with a GREAT WHITE, the shark would eventually either bite the dolphin, or the dolphin would run away.

I'd rather be surrounded by a group of dolphins, if I'm swimming in the sea, than a single shark. Though not all shark species will attack a swimmer.
no, sharks are totally different than whales and dolphins because sharks are fish, not mammals like a dolphin or a whale.
5 miles per hour more
Dolphins are generally near the top of the food chain. Occasionally a shark will eat a dolphin, but other than that, the only other animal to eat dolphin is humans.
Being of not all creatures underwater are not fish, yes. For example a dolphin, or a shark. Fish are classified as "Tetrapod's".
There are some species of sharks that can swim faster than dolphins (some sharks eat dolphins) but there are on the other fin, species of shark that dolphins are faster than. Mako sharks for instance, do swim at bursts of speed of 50 miles per hour making makos the fastest animals in the ocean. On average speed wise, between dolphins and sharks 50/50. Hope this answers the question.
Most ocean creatures developed this trait for protection from predators. It works like this: Lets say a dolphin is swimming through the water and a hungry shark it swimming below it. If the shark were to look up, he would see the dolphin's light belly blending in with the light from the surface. This makes it hard for the dolphin to be detected and eaten.
