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.
Great white sharks are capricious fish. They are iconic, impressive, photogenic, and awe-inspiring but also frustrating. That frustration is not all about the animal — part of it is how few places in the world you can go to see them.

Our explorations of Belize’s equally biodiverse jungles and reef systems some 4,000 miles (6,437 kilometers) south repeatedly reminded me of that endless summer afternoon in Alaska.
My phone’s alarm filled the air, but I was already awake. It was the day I had eagerly anticipated since first learning about the Florida International University (FIU) Introduction to Saturation Diving: Aquarius Operations and Benefits to Science course — the emergency simulation.
I was diving with my wife, Kristy Hiltz, in remote Kimbe Bay, Papua New Guinea. We had taken all the necessary precautions and dived according to our computers. On what turned out to be our last dive, we sat on a rock ledge at 70 feet for 15 to 20 minutes and then made a slow ascent, completing a full safety stop.
Following the white sand beaches and emerald waters along the Florida Panhandle leads to a diverse set of wrecks and artifacts ranging from oversized sculptures to the largest purpose-sunk wreck in the U.S. This area of Florida is known as the Emerald Coast, and the visibility in this part of the Gulf of Mexico is superior to that along the Louisiana and Texas coastlines.
It is early June, the onset of winter in the Southern Hemisphere, and an army has just reached its destination. It has marched from the ocean’s depths into the shallows, amassing among the pilings at Blairgowrie Pier in Port Phillip Bay, south of Melbourne, Australia.
