Doctor and diver Ben Burville made friends with a young female grey seal that became used to seeing him dive in her waters.

I would advise that divers do not touch marine life. Notably grey seals have a range of rather unpleasant bacteria in their mouths and these bacteria can cause serious infections. (Including various mycoplasma and streptococcus species)
