Can Cephalopods “See” with their Skin?

Wednesday, 06 April 2016 22:20

By Alex Rose

There are few marine creatures as fascinating to watch as cephalopods. From their tentacles that each seem to move autonomously, to their unbelievable ability to change colour and texture, to their alien feeding habits, these molluscans never cease to amaze us.

Although they may look absolutely nothing like clams, cephalopods are considered mollusks and are more closely related to bivalves than any other group of sea creatures. Octopuses, squid, cuttlefish, and nautiluses all belong to the class Cephalopoda, which means “head foot.” Mollusks in general are not known for their intelligence and most don’t even have a proper head, let alone an impressive brain, but cephalopods differ drastically in this regard.

Shark Story: How a Tiger Touched my Heart

Monday, 28 March 2016 17:52

By Vanessa Mignon

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.

Exploring the Moon on Earth

By Cristina Zenato

The horizon is the beginning of my world. As I started as a young diving instructor in the Bahamas I used to ride the boat sitting on the roof with fellow instructors, soaking in the morning sun rays, as the boat glided over a shimmering road of glittering sea. It was perfectly paved to show us the way to the first dive of the day, the first adventure.

“Bubbles Away”- Oceanic Omega 3 Review

Thursday, 22 September 2016 02:37

By Brett Lobwein

 

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.

*Check with your local dealer that this is standard in your location
