Shark Bite and Shark Attack: Shark attacks can be categorized into three types, hit and run, bump and bite, and a sneak attack. You can potentially avoid a shark attack or shark bite by taking precautions such as not wearing shiny jewelry, not splashing in the water, not entering the water if you have an open cut that is bleeding, and paying close attention to your surroundings. Shark bite treatment depends upon the severity of the wound.
