How many great whites are there
Modern hunting techniques were wiping out humpback populations in following years and there were just three fatal shark attacks from to By the s there were less than adult humpbacks off the WA coast. Since there have been 19 fatal attacks on swimmers, divers and surfers, with one blamed on tiger sharks, two unknown species and the rest great whites.
The whales disappeared and the sharks disappeared. The whales returned, the sharks returned, and this time they've found a lot more humans swimming nearby. Albeit a dubiously low figure, a survey desktop site suggested there were just 3, left on the planet. Great whites are not a strictly coastal species and are know to swim between South Africa and Australia through cold lower latitudes, their habitat including several thousand kilometres north along the WA coast.

They are threatened by overfishing, according to the World Wildlife Fund , and their global population is in decline.
On the Pacific coast, however, the sharks seem to be doing well. Chapple and his team originally published a population estimate for sharks off Northern and Central California in The new research updates the previous estimate with longer-term observations. Great white sharks are known to be highly migratory, with individuals making long migrations every year. In the eastern Pacific Ocean, great whites regularly migrate between Mexico and Hawaii.
In other ocean basins, individuals may migrate even longer distances. Like in many highly migratory species, the very largest individuals are female. Though they give live birth, great whites do not connect to their young through a placenta. Instead, during the gestation period, the mother provides her young with unfertilized eggs that they actively eat for nourishment.
