Scientists Discover a New Non-Invasive Method to Track Sharks

Sharks
A recently published UK study has unveiled a new less traumatic method of monitoring sharks - via environmental DNA (eDNA). Marine ecologists have shown that even a small sample of seawater can provide the identifiable 'tracks' of numerous species of sharks, rays and other large fish. Current methods of baiting, hooking and filming these animals are invasive, costly and require teams of scientists spending much time at seas.
