Reddit reviews The Devil's Teeth: A True Story of Obsession and Survival Among America's Great White Sharks

Is there a geographical disparity between where sharks are tagged? I skimmed the site and it seems like they focus on Atlantic sharks but there are ones in various other places. I'd just like to know more about their methodology before drawing conclusions about where they predominantly live. For instance, the Farallon Islands off of San Francisco are a known meeting place for great whites from all over the pacific. I don't remember all the details but eh... I read that one book by Susan Casey that was interesting. Thank you for providing an interesting data visualization!!
