It depends on what kind of shark it is. The sharks mistake swimmers for seals and other pray. It doesn't happen on purpose.
Yes.

Sharks polar bears sharks clownfish and blue whales
well it depends..... if you believe Jaws then yes but if you really look at sharks, they really only eat seals fish etc. they rarely attack people . and they attack surfers more then swimmers because they have the black wet suits and they think there seals so yes and no
KIller Whales do not attack sharks and they do not attack anything that they see. Killer Whales only eat small sharks and fish because No creatures are mindless killers there is always a reason
No, human swimmers are not usually in great danger from sharks. Shark attacks on humans are rare, and most shark species are not interested in preying on people. It's important to practice caution in areas known for shark activity, but the risk of a shark attack is very low.
Yes they are, they can swim up to 2.4Km
Yes, sharks will attack people whether they are white OR black. But sharks tend to attack white people more.
Hammerhead sharks can eat swimmers. However, they do have very small mouths compared to other sharks. This will make them have a harder time trying to bite and devour you. Sharks are not aggressive animals though, so you should not worry unless you are provoking them.
Both Dolphins and Sharks are predatory animals. They often hunt and breed in areas accessible to one another. The acts of violence toward each species can simply be due to the fact that each may be competing for hunting territory, to protection of offspring. Sharks do attack dolphins, even the related Orca(killer whale) as prey, so dolphins will attack sharks for purpose of protection. There have been recorded incidents of dolphins "protecting" human swimmers from shark attacks( by attacking sharks or swimming around humans to drive sharks away) but it is probably because dolphins don't see humans as threats, and have an instinctive emnity toward sharks.
