I first dived the Red Sea just after Moses and the Israelites had crossed it. No, that’s an exaggeration but now it does seem like a very long time ago. Scuba-diving was in its infancy and most of the experienced dive-guides had learnt their business from being backpackers who had a go at diving. They did a lot of diving and had a tremendous amount of experience together with masses of in-water confidence, yet their theoretical knowledge of diving could be a little sparse. The calm clear deep water invited the intrepid to go deep. There soon grew up among dive-guides a deep-diving culture that was to claim many lives. The Blue Hole at Dahab regularly claimed divers and, in those days, military ‘helium-divers’ from the Israeli were called in to recover the bodies.
Lionfish carry a deadly poison in their spines. Lionfish are not poisonous, they are venomous. The difference between poison and venom is the method of delivery. Venom must be injected into the bloodstream to cause injury, such as through a sharp spine or fang, but is harmless if drunk or eaten.
