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.

Hollis Explorer Rebreather

Thursday, 07 January 2016 20:38

Review by Billy Snook

Rebreather technology has been around for about a hundred years but it hasn't been until recently that it has become practical for the masses of recreational divers. Bob Hollis & Company have done just that, and they are selling and promoting a truly recreational semi-closed rebreather aptly named the Explorer. The advantages of diving an Explorer are that the diver makes very little noise as compared to conventional open circuit diving, available dive times are much longer (as long as three hours), and you’re breathing warm, moist air instead of the cold, dry air and subsequent dry mouth characteristic of an open circuit system. Not blowing bubbles affords the diver much better marine life encounters and photographic opportunities and is ideal for wreck diving so as to avoid disturbing silt and drastically decreasing visibility.
