Blue Sea Cruises does not participate in the activity of allowing swimmers to enter the water to swim with the dolphins. We believe this activity harms the natural behavior of the dolphins and interrupts their much-needed rest during the day.
Studies have shown that Spinner Dolphins are especially vulnerable to human disturbance. Spinners follow a predictable pattern of traveling off shore in the later afternoon to dive down and feed on deep scattering layer animals that rise from their midwater regions towards the surface at night. In the early morning, spinners move in towards shore, especially on the leeward sides of the Big Island. After traveling along the coast during the morning, the spinners go into a rest period during the day.
