Dolphins
Dolphins are one of the friendliest creatures you’ll ever encounter in the ocean. Unfortunately, they can also be pretty deadly. Usually they’ll only use their sharp teeth and strong tails to attack predators. But over the last couple of years, human deaths have risen as a result of attacks led by dolphins who became agitated or felt like they were being provoked by people. In rare cases, death can occur if a dolphin gets too excited and slams into a human’s torso, causing fatal bodily harm.
