When diving with sharks, you should always be alert and aware of your surroundings. Also, just like all dives, you should know what you're getting into before diving into the water. You should take some time to research on the depth and visibility of the water as well as the types of sharks that frequent the place. When you see a shark, you should make sure that you always know where it is before it leaves the vicinity. Try to stay crouched down on the sand and be as motionless as possible while it is there. Sharks tend to be very agitated when there is a lot of movement. These are some of the precautions that you should follow when diving with sharks.
