Great white sharks are at the very top of the marine food chain. Feared as man-eaters, they are only responsible for about 5-10 attacks a year, which are rarely fatal. Great whites are ultimate predators. Powerful streamlined bodies and a mouth full of terrifyingly sharp, serrated teeth, combine with super senses that can detect a single drop of blood from over a mile away. Hiding from a great white isn't an option as they can detect and home in on small electrical discharges from hearts and gills. Unlike most other sharks, live young are born that immediately swim away.
