Answer 2

Sharks communicate using their body language, things like how they swim also comes into play.
Usually shark communication is bahavioural eg. they arch their back & swim in an aggressive S pattern when aggrovated. Also their Pectoral fins (the bottom fins) point downwards when they are unhappy about something.

Answer 3

they can protect themselves by eating and leaving dangerous things behind that they know not to touch or eat

The shark's body is streamlined to swim quickly through the ocean and away from predators. It can swim about 22 miles per hour, and even faster in short bursts. Some sharks are bottom dwellers--they spend a lot of time at the bottom of the ocean--and they are camouflaged to blend in with their surroundings. These sharks will lie quietly, unnoticed, until their prey comes along, then suddenly snatch their unsuspecting prey. A shark has scales on its body called denticles, which are like tiny teeth embedded in the shark's skin. Denticles can injure a fish if it rubs against the shark the wrong way. Perhaps what a shark is most known for is its teeth. Sharks have several rows of teeth, and can have up to 3,000 teeth at a time. A shark has so many teeth because of the way it eats. It bites and jerks its prey around so violently, that the shark loses many teeth in the process. When a shark loses a tooth, a new one grows in its place.

Sharks use their different senses for protection. They have tiny holes all over their heads called the ampullae of Lorenzini. These are nerve receptors that sense electricity in the water. Animals give off electrical currents when they move, which sharks can sense.
