Some sharks can shed 30,000-plus teeth in a lifetime. When a shark sheds a tooth, a new one rotates forward, replacing it within 24 to 48 hours. | National Aquarium

Sharks continuously shed their teeth. Some shark species can lose up to 35,000 teeth throughout their lifetime! Sometimes we are at the right place at the right time and can catch them before they hit the seafloor. #tigershark #sharktooth #savesharks #sharkdiver #sharkdiving | Kayleigh Nicole Grant
