1 Angina Pectoris: It is described as a pain located at the back of the breast bone which may be sharp or dull. This sensation may radiate or crawl to the hand, arm, left shoulder, or jaw.  Vasculitis: When the small to medium sized arteries are inflamed, head tingling and numbness may result.
Most species of shark eat things like fish, crustaceans, mollusks, plankton, krill, marine mammals and other sharks. Sharks also have a very acute sense of smell that allows them to detect blood in the water from miles away.
By raising its head several feet out of the water, a White Shark may be better able to detect airborne scents that could indicate a rich source of food in the otherwise featureless expanse of the open ocean. To what extent the Great White relies on its sense of taste is also a matter of conjecture. There are a few, scattered reports of other sharks apparently rejecting food on the basis of taste, but this has not been tested.
