by Ksso on February 08, 2011

The Pufferfish ( scientific name : Tetraodontidae) is a fairly common fish that can be encountered especially easily on the US , Australian and western African coasts. The Puffer fish can be also referred ad balloonfish, blowfish, bubblefish, globefish, swellfish, toadfish, toadies, honey toads, sugar toads, and sea squab and represents a family of about 121 species within 20 genera.The blowfish eat mostly crustaceans and mollusks whose shells they crush with their four teeth (thus the scientific name).Puffer fish are generally believed to be the second–most poisonous vertebrate in the world, after the Golden Poison Frog. One of its best known representant is the japanese Fugu fish which...

Decompression theory - How it all began

by Ksso on February 08, 2011

The decompression theory is one of the key techniques enabling regular people to go discover the marvels of the oceans in a somewhat secure context. Diving is dangerous, since the first time you go diving, all scuba divers have been warned about the risks of a DCI (DeCompression Incident).Why the DCIs ? A DCI can be an unhappy consequence to a fairly simple phenomenon : the off-gazing of Nitrogen (N2) held in your body tissues. When you go for a dive, pressure around you increases. Likewise the aire that you are breathing gets to the same pressure as your environment.Air is made primarily of 78% N2, 21% of O2. While O2 gets "used" by your organism, N2 is useless and will be diluted within...

How nets kill to protect our fears

by Ksso on February 06, 2011

Shark Angels - on Shark Nets from Shark Angels on Vimeo.

Very striking video made by the "Shark Angels" about the rampage done by nets. The most appalling thing is that those net don't only target sharks but dolphins, turtles and other harmless animals die there too.Again, it's a recall that actually few types of sharks are dangerous: of the existing 368 species of sharks, only 20 are dangerous to humans. Of them, four account for almost 60-70 shark attacks registered annually worldwide.If you were as appalled as I was by those images, go ahead and sign the petition at removethenets.com .

Common hand signals

by Ksso on February 05, 2011

If you haven't been diving for a while, before getting back in a suit it's always a good idea to review the basic hand signals used for communicating underwater.... you know, just in case you need them ( and to make sure you don't thumb-up your dive buddy ... (thumb-up means we're going up now)).There are more gestures than that and you should think while on the boat to reassess those that may be used during the dive to point on the rare fish you may run into.Common Hand Signals for Scuba Diving

Dive western Bali - Geko dive

by Ksso on February 03, 2011

Indonesia is an amazing place to dive containing 10 - 15 percent of the world's coral reefs. Indonesia consists more than 17,000 islands and becomes the largest archipelago in the world with at least 80,000 kilometers of coastline.View Larger MapAmongst those island, Bali stands out by the variety of its landscapes and the kindness of the Balinese people (and their super-yummy local dishes).I went on a vacation there for 2 weeks in 2006 and we chose the western side of the island. The southern coast is traditionally more touristic as it is closer to the airport and Kuta, the capital city, looks like a giant night club. If you want some quiet time you definitely need to avoid this side of...
