Speak of the Spiny Devilfish
The spiny devilfish (Inimicus didactylus) is a member of the family Scorpaenidae, which also contains the venomous lionfish, stonefish, and scorpionfish. These fish conceal glandular venom-producing daggers within their dorsal, pelvic, and anal fins. Divers — especially underwater photographers who may focus on one creature while others sidle up under their legs — must be aware of these animals’ subtle defense maneuvers.
Nutrition optimale pour la plongée
La plongée sous-marine exige non seulement une bonne condition physique, mais aussi une préparation nutritionnelle adéquate. Comme pour toute activité, nous dépensons de l’énergie en plongeant ; de façon surprenante, l’énergie nécessaire pour une plongée récréative habituelle reste relativement modérée. Dans des conditions récréatives exceptionnellement exigeantes, il est toutefois possible de brûler plus de 500 calories.
Training Is Everything in a Rescue Attempt
Many divers are proud to be comfortable in the water and sometimes push their limits on air consumption, exceed their bottom time, or take one last shot of a big fish with a camera or spear before ascending. Some of them develop reputations in the dive community for being competent divers by looking cool and experienced while taking little risks. It may start small but snowball into making poor decisions for which the price you pay is not worth the reward.
Learning from the Conception
On Sept. 2, 2019, the small passenger vessel Conception burned to the waterline off Santa Cruz Island, California, killing 34 people. This wasn’t the first liveaboard fire, but the fearful reactions to this deadly tragedy echoed throughout the scuba industry. Liveaboard fires that have occurred since this incident have further fueled industry concerns.
Diving After an Eye Stroke
Q: I recently had an eye stroke. Can I still dive after it has been resolved? A: The main concerns with an eye stroke (central retinal artery occlusion, or CRAO) are the underlying cause and the medications your doctor prescribed for treatment. Before returning to diving, work with your ophthalmologist or physician to determine the root cause of the initial ocular stroke, the probability of recurrence, and your overall cardiovascular health.
Gerald Nowak: Extreme Environments
Over the years I have often admired Gerald Nowak’s underwater photos. There is so little overlap between the markets available to European versus North American photographers, however, that I did not know the backstory of his career. A recent phone call rectified that.
Welcome to Shoulder Light
Imagine waking up in the early hours of the morning at your favorite dive site. The sun hasn’t quite peaked above the horizon, and light is minimal. You don your dive gear, grab your camera, and giant stride off the back of the boat to begin your descent into the dimly lit ocean.
Fighting the European Green Crab Invasion
One of the world’s most destructive invasive species is gaining new ground — or water — in Canada and up to Alaska. Carcinus maenas, which translates to “raving mad crab,” outcompetes many local crab species in devouring clams, oysters, and mussels, and they sometimes even eat other crabs and juvenile fish. They destroy seagrass, an essential habitat for juvenile salmon, herring, rockfish, and many other marine animals.
