Report an Encounter: Great White Shark

Researchers around the world have each begun to develop their own databases of white sharks that they see. The way the identify individuals – the fins. Great white shark fins have serrated trailing edges that are unique and are believed to stay the same over the course of the animal’s lifetime. The OCEARCH tagging project has witnessed their SPOT tagged sharks swimming into Mozambique, one of which had been caught in the shark finning business. It is of great international interest to determine the migration strategies for these animals to better protect them across South African and Mozambican boarders.

If you see a great white shark, the best way to photograph the fin is to get the animal near to the surface and photograph from the comfort of a boat. The fins, albeit after being dried, still maintain the notches on the trailing edge of the fins. If you are able to photograph the fins on a light background, such as the sand, these can be used to identify the individual. Even if no images of the animal are obtained, please notify us as to the presence of white sharks in Mozambique.
