Great Whites on the Rise
Scientists and shark conservation organizations like Shark Stewards call this period “Sharktober” to describe the period of heightened great white shark (hereafter called white sharks) activity and human encounters along the California coast. As the fall season arrives along California’s coastline, a compelling and cautionary period for ocean-goers occurs when adult great white sharks return to California waters. These fall months coincide with an increase in human -shark interactions and a few, but rare, high profile human shark interactions, (aka shark attacks.) Here we discuss the incidence of great white shark human interactions* along the West Coast of North America, the relative risk and how to avoid becoming the next statistic.
