Our thanks to the people at the resort Club Ocellaris: the friendly and helpful staff, always ready with meals when we returned (often late) from dives; the excellent boat operators and crews; and the terrific dive guides Peri and Alexis and others, without whom we would have seen far less. Thanks also to our fellow nudi-philic divers, all willing to share their finds so we could all see as many slugs as possible.
