its like impossible to tell a sharks age without tkaing its vertebrae out which kills it so we usuLly have to guess with info we have .. also scientists stick tehir hands into some kinda of sharks mouths to take our their stomachs and see what they eat its awesome and it soesnt harm them iirc
i love them did you inow tiger sharks just follow people around. like rheyre really curious there is videos of them just tryna run over people because theyll just eat anything and they just have to be gently redirected
