The basking shark (Cetorhinus maximus) is the second-largest living shark. It is one of three plankton-eating shark species, along with the whale shark and megamouth shark.
Read MoreIn the Northeast Pacific, adult white sharks annually migrate far from USA and Mexican protection and are vulnerable to being killed as bycatch on international longliners or shark finning on the high seas. This is one of the reasons we celebrate their return to Sanctuary during Sharktober each year!
Read MoreScientists 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.

These statistics underscore the critical importance of strengthening global protections for these vulnerable marine predators.
Read MoreA study published in the journal Fish and Fisheries this month revealed that fisheries could reduce shark death by requiring the release of threatened sharks caught as bycatch by at least three times. Known as retention bans, the practice requires that fishermen release certain sharks that are endangered or unwanted rather than retain them for their fins or some other use.

He manages the Sevengill Shark ID Project, which uses the pattern recognition algorithms contained in ‘Wildbook’ to help identify Sevengills returning to La Jolla [and Cape Town] from year-to-year. We are leading dive trips and recruiting divers who dive the san Diego area to submit photographs of sevengill sharks to photo ID using an algorithm.
