Spinner dolphins are seen near Keahole Point, Hawaii. More people and more activity in Hawaii waters means more impact on ocean creatures, and the entertaining spinner dolphins may be the most stressed. Dolphins constantly performing for tourists can suffer disruption in their eating and reproduction habits and become more vulnerable to predators, according to Steve Soto-Amundson of the South Kona Preservation Coalition.
