Although great hammerhead sharks (Sphyrna mokarran) appear powerful and robust, recent research has shown that they are in fact one of the most fragile shark species, being particularly vulnerable to the stress of capture. Even those that are released after being hooked have a nearly 50% chance of succumbing after their ordeal.1 To better protect these sharks, a greater understanding of their movements is needed. The results of a new study conducted by scientists at the Bimini Biological Field Station in Bimini, Bahamas have provided a major step forward by showing the migration patterns and regional connectivity of great hammerheads between the Bahamas and the United States.

As I look at the dozens of shark fins breaking the surface, I cannot help thinking about my mum’s face if she could see what I am about to do. Here I am, in the Bahamas, getting ready to jump in the middle of sharks!
I gear up, thinking about the crew’s advice; when you get in the water, go straight to the bottom. There is no cage and no protection, just my camera and the hope that I am too skinny to be even considered as finger food! My heart is full of excitement and anticipation.

Over the last decade I have spent hundreds of hours studying the science and conservation of sharks and the ecosystems they inhabit. I have come to a full understanding that the ocean is not only the life support system of the sharks I have compassion for, but it’s the lifeblood of the human race, too. Yet here we are tanking its health with all manner of our consuming compulsions.

Indonesia is regarded by many as being the best country in the world when it comes to dive sites, and the diving around Bunaken does everything to uphold Indonesia’s prestigious reputation.
Bunaken is a small island in North Sulawesi and it is one of 5 islands, which make up the Bunaken Marine Park, which was one of the first marine protected areas declared in Indonesia. The move by the Indonesian government to protect the area in 1991 was made due to the extreme marine bio-diversity the area supports. The islands of Bunaken, Manado Tua, Siladen, Montehage and Nain are home to numerous rare and endangered marine creatures which include coelacanths, dugongs, whales, turtles and dolphins but it’s not just these “special” species that make Bunaken a phenomenal diving destination.

The Oceanic Omega 3 side exhaust regulator is the perfect choice for underwater photographers, videographers or SCUBA divers who want to avoid any distraction from focusing on the ocean. Apart from the exhaust [flow] bubbles being directed away from my face, as a photographer I really like the Omega 3’s profile. Being a side exhaust means there is not a bulky regulator pushing up against the back of the camera housing as you look through the viewfinder.
The biggest ‘upgrade” of the Omega 3 over the very popular Omega 2 is that it no longer breathes wet. It comes packaged out of the box with a MaxFlex hose* and a ball swivel, making it very comfortable plus dramatically reducing the regulator pulling against your jaw. Tech divers will also love that this regulator is ambidextrous “no up or down”, making it an ideal choice for a side mount setup.
I have managed to test the Omega 3 to a depth of 52 metres (170 feet). The entire way from the surface to 52 metres the Omega 3 delivered the perfect amount of air without the need for any complicated adjustment knobs. A simple twist operated dive/pre-dive switch is very handy to stop any free flowing on the surface.
Oceanic has paired the Omega 3 with the lightweight and top-performing FDX-i first stage. For those who want to explore colder oceanic waters, the FDX-i is ready with an environmentally sealed diaphragm. As you would expect this first stage is also balanced, which ensures the regulator performs consistently at any depth. I have also been very impressed with the well thought out port layout and positioning. The FDX-i uses Oceanic’s Dry Valve Technology (DVT) preventing water or other foreign objects from entering the first stage, ideal if you forget to put the dust cap on.
Complimenting its modern design, the Omega 3 comes in three colour choices—black, white or clear. Personally I love the clear, as it allows you to see the beautifully engineered internal workings of the second stage. After owning the Omega 3 for over 12 months, I am still blown away by its performance.
