Fish feel pain, or don’t they? Despite a growing body of sound evidence that fish do indeed feel pain and are sentient beings capable of all the types of cognition found in the “higher” mammals, with the possible sole exception of the ability to imitate, a group of critics seems to systematically seek to discredit this research. But for what reasons? Ila France Porcher takes a closer look at the stakes involved.

On a night dive in the Philippines several years ago, I had an opportunity to do a "fluoro" night dive. Atlantis Dive Resort rented blue underwater flashlights and yellow filter shields that went over divers' masks. Geared up, I set off into the night. The blue light was very dim and the dive was much darker than a normal night dive. After a few moments of wondering what exactly I was doing underwater in the blackness of night, my eyes started to adjust and the first fluorescent colors started to show up.

The pursuit of unusual and compelling photo opportunities has led me on some interesting journeys over the last few years, but few come close to the raw excitement of photographing the American crocodiles of Mexico’s Banco Chinchorro! I have come to realise that photographing big and charismatic animals underwater actually borders on the addictive, because the more of those trips you do, the more encounters you hear about and the “must-do list” just keeps on growing. So it was when a conversation over an après-dive adult beverage led to the subject of in-water encounters with crocodiles.

Over a number of years, the actions of fishermen and sea anglers have attracted the attention of marine scientists at the Dunstaffnage Marine Laboratory who quickly became aware of these fishers catching spurdogs in the Loch Etive area near Oban on the west coast of Scotland. These small sharks were always on a catch-and-release scheme, and the researchers thought that this little British shark deserved a bit more interest in order to discover what they were up to, trying to learn more about their habitat and habits, and why Loch Etive was so important to the Scottish population of these fascinating sharks.

Adding some realism to your training protocol also requires adding spontaneity, distraction and surprise. This is not as hard as it seems, but it can be dangerous for instructor and student if not well-controlled.

Mike Ange discuss methods of building a safer and more comfortable diver at the more advanced levels by preventing the diver from anticipating issues before they occur. While this may sound contradictory to the earlier articles in this series, in reality, it is taking those skills to the next level.

You are chatting with a diving friend and the conversation turns to mutual acquaintances. “Do you know Bob and Carol?” your friend asks. “Oh yes, good divers!” you reply. We will usually refer to someone as a good diver when they are not around. We will rarely say it to their face. And it is something that we all rather hope people say about us behind our backs. And of course, the politically correct response when someone says, “so-and-so is a good diver” is to nod sagely in agreement, rather than object. But what does it mean? What are the qualities that make someone a good diver?
