Divers learn to steer clear of sharks and other predators who see them as a snack, and they tend to keep dolphins and other inquisitive mammals at bay for safety's sake, but their relationship with seals remains uncertain.
That's because seals have been known to attack humans in the water for no apparent reason, and their playful and curious nature can result in injuries for humans they decide to use as a plaything.
But when diver Gary Grayson was approached by a curious seal while diving in the Scilly Isles he wasn't afraid or worried about being attacked- because he was just as curious about the little critter as the critter was about him.
Next thing you know the seal did something totally unexpected- he flipped over and asked Gary to rub his belly!
