Meet - The Blue Shark. They always look like they're smiling. They can be found in all waters around the world (except the arctic regions) but particularly enjoy water temps between 50-68 degrees. Sadly, despite not being aggressive toward humans, they are the most fished shark. It is estimated that humans kill up to 20 MILLION blue sharks EVERY YEAR. Please share this to show how beautiful these sharks are and to raise awareness that they need humans to protect them not be the cause of their extinction. #BlueShark, #CabosMexico, #LureenFerretti, #MarineLife, #Shark, #UWPhoto, #UWPhotography, @SharkDivingDiva, #SaveOurSharks, #SharkConservation, #animal_captures, www.DeepWaterPics.com https://www.instagram.com/p/BvvF1sAFZWA/?utm_source=ig_tumblr_share&igshid=jwvturw2vh2b
