Sharks only attack when they are hungry or not well fed, I don't quite know how they act if they are normal probably they will ignor you.
People usually react to sharks with fear. Sharks are a predator and fear is a natural response.
Sharks do not react to water because they are used to it but if they are babies they might be scared of the water because they are not used to it so they swim to their mom
No, not typically. Generally, people react to poison ivy, oak or sumac. Generally, animals be they domesticated or wild don't react. But there may be exceptions.

Sharks are typically "fusiform".
people can see sharks and fishes at the ocean.

Yes, sharks will attack people whether they are white OR black. But sharks tend to attack white people more.
Sharks don't eat people. They eat little fishes.
How many people are swimming in the ocean depends on several factors. It depends on the time of year, location, and what time of the day or night it is. Sharks typically hunt aggressively at night, but some people believe that sharks hunt the most aggressively at sunset and sunrise.
Typically, sharks and dolphins avoid each other. On occasion however, sharks such as the great white will hunt baby dolphins. Dolphins are tough creatures and sharks have learned to ignore them, for the most part.
Sharks rarely come near shore at beaches. Unless you're swimming with sharks, I wouldn't recommend swimming. Blood makes sharks react and could kill you brutally.
