#Regram #RG brianskerry: Photo by BrianSkerry. A Thresher shark dead in a gill net off of the coast of Baja California in the Sea of Cortez in Mexico. Every year, over 100 million sharks are killed as a result of human activity – often for their fins. Look out for new posts to learn more about shark conservation, and to see more underwater photography. thephotosociety natgeocreative #thresher #shark #conservation #extinction #climatechange #pollution #onassignment #photooftheday #savesharks #nikonambassador #nikonlove #nikonnofilter
