How to tell a white shark from a basking shark dorsal fin

Spring has finally sprung on the Cape, which means many marine species are on the way back to our local waters.  Anyone who uses our free app, Sharktivity, can report white shark sightings to the app, but white sharks are not the only large sharks you may encounter at sea.  Basking sharks are also seasonal visitors to the Cape and can often be seen swimming at the surface.

Fisheries Biologist, John Chisholm, from the MA Division of Marine Fisheries put together this informative guide on how to tell the difference between a white and basking shark dorsal fin.  

Remember to be Shark Smart this season and to report your sightings!
