Little is known about the reproduction of white sharks. The white shark becomes reproductive when it is about 15 years old.  The maximum lifespan was previously thought to be about 30 years, but in a study by the Woods Hole Oceanographic Institute, the true life span of a white shark can be as high as 70 years or more.  Tests of the sharks have shown that their maximum age is 73 years and that of female sharks maximum is 40 years for the specimens studied. The late maturation of sharks, low reproductive rates, a long 11-month gestation period and slow growth make them vulnerable from overfishing and environmental changes.
The process of jumping into the air is the result of a high-speed approach to the surface with momentum that attracts sharks partly or completely in the water. This is a hunting technique used by great white sharks while hunting seals. This technique is commonly used on the Cape fur seal on Seal Island in False Bay, South Africa. Because behavior is unpredictable, it is difficult to record. It was first captured by Chris Fallows and Rob Lawrence, who developed the technique of pulling slow-moving seal prey to trick the sharks into jumping. From April to September, scientists can observe about 600 times sharks launch out of the water to catch prey. Seals swim across the surface and great white sharks launch their predatory attack from the deep water below. They can reach speeds of up to 40 km / h (25 miles per hour) and can sometimes launch more than 3.0 m (10 ft) into the air. Only less than half of these attacks were successful.
