  2. 1. Sharks are attracted to electrical pulses emitted by some boat motors.
    2.It happened about eight miles into the Gulf of Mexico off of Panama City Beach
    3.It was at least 10 feet long.
    4.Sharks have the ability to detect electromagnetic fields with their Ampullae of Lorenzini. These are 'jelly'-filled pores at the tip of the nose/snout of elasmobranchs designed to pick up minute electric pulses put off by muscle contractions of their prey.
    5.Sharks tend to "taste" potential food items, be they a human leg or an old inner tube, to see if they're worth eating. (All depends on its hunger)
