Observe wild dolphins, porpoises, and seals from safe distances of at least 50 yards. You could use binoculars or telephoto lenses for a better view of the animals, limit overall viewing time to no more than 30 minutes. Avoid circling or entrapping marine mammals between watercraft, or watercraft
and shore , avoid abrupt movements or loud noises around marine mammals . You need to try and AVOID separating mother/calf pairs and move away cautiously if behaviors are observed that indicate the animal is
stressed. You can also try to avoid them even if they do come to you. it's more than three, but there ya go :)
