Sawfish are one of the most endangered fish in the world, and Atlantic tarpon are considered vulnerable. Both fish move into salty and fresh water, but we don't understand these movements. Knowing more could help identify ways to protect both species. Luckily, tarpon scales and sawfish rostral teeth store chemistry that can reconstruct the movements they make. We hypothesize that teeth and scales will allow is to reconstruct the movements of both fish in a non-lethal way.
