Great whites are armed with an array of adaptations that make them extremely efficient predators. They display a multi-rowed arsenal of continuously growing serrated teeth, and around two-thirds of their brain is taken up by the olfactory lobes, allowing them to detect as little as one part per million of blood in the water. Great whites often approach their prey from below and at high speed; at 32 km/h they can break the surface with such ferocity that their not inconsiderable bulk is launched clean into the air.
