Nick was supposed to be our "safety diver," but we don't have time for that now. He has to film too. When the opportunity arises, we must seize it!

After the discovery that around 70 protected porpoises were probably dumped from a fishing boat in the harbor of Lysekil, the coast guard has now started a preliminary investigation into fishing crime or serious fishing crime
Deep Sea Reporters/Tobias Dahlin's minute-long film footage of the shark massacre in Lysekil harbour basin has provoked strong reactions.
