If a creature comes up to you and initiates contact like some octopus and eels then fine. Otherwise the no touch rule is a good one. Regarding mantas, the Hawaii population that frequents the Kona night dive show skin infections from the frequent contact with divers. The shops say it is not seen on the mantas that are not seen at the night dive.
As we all know more and more people are diving. Maybe 20yrs ago it was just one stressful incident in the rays, eels, puffer fishs life. Now with so many people diving the same areas the no touch just makes sense. As divers we should take it on ourselves to talk about it after the dive with the offending divers. I think it is a hard thing for dive guides who are dependant on tips for a living.
