Not to hijack the thread, but gloves also provide protection when decending and ascending anchor lines, which are often encrusted with sharp barnacles and other marine life. They also assist in gripping rope lines during zebra boat tows and exiting the water on wet slippery metal ladders. In times when it's necessary to push off coral reefs/walls or make a hold fast, a gloved had is better for the diver and reef. I don't understand the argument that allowing gloves incentivises divers to touch/handle marine life or reefs more. Careless or bad divers are going to do it anyway and if they do, THEY should be warned or have their diving restricted...not experienced and conscientious divers.
