Sharks exist since more than 400 milion years. They play an important role for the stability of the marine ecosystem. In less than 100 years the industrial fishing industry has brought many shark species to the brink of extinction. In my talk about sharks I tell you about the fascinating skills the sharks have and the role they play in the ecosystem. I also talk about the interference of the humans with the sensitive system.
