Video by @paulnicklen // What lies beneath California’s thin blue line? Blue sharks are one of the most graceful and beautiful animals I have had the pleasure to engage with underwater. Even though they may be a top predator in their domain, they are no match for California’s swordfish driftnet fishery. These mile long, 100-foot deep nets entangle and kill countless sharks annually. Is it worth having swordfish on our menus and risking the survival of Californian coastal species? #Followme on @PaulNicklen to see the impacts that driftnets are having on California’s charismatic megafauna including dolphins. #TurningTheTide with @sea_legacy
