True Facts:The Anglerfish True Facts:The Anglerfish
LiveBait - 6 days 6 hours ago.
The anglerfish is so called because of its method of predation. This is the fish that goes fishing. It has a long, modified dorsal fin spine sprouting from the middle of its head that ends in a fleshy growth that can move and wiggle to resemble another animal. In some deep sea anglerfish this deadly bait can even emit light (bioluminescence). Passing predators who think they’ve found an easy meal only need to touch the bait to find out they’re the main course....
Wounded Sea Turtle Gets A 3D-Printed Jaw Wounded Sea Turtle Gets A 3D-Printed Jaw
LiveBait - 9 days 9 hours ago.
In an earlier era, colliding with a boat’s propeller could have been the end of a sea turtle’s life. This is not that grim dark era, so a sea turtle found with a broken jaw was rescued and then brought to Pamukkale University’s Sea Turtle Research, Rescue and Rehabilitation center in Denizli, Turkey. Thanks to a collaboration with Turkish company Btech Innovation, the turtle received a custom-designed, 3D-printed titanium jaw. Read More:
The Only Warm Blooded Fish (that we know of). The Only Warm Blooded Fish (that we know of).
LiveBait - 11 days 6 hours ago.
This goes against everything I was ever taught since elementary school, on how all fish are cold blooded. This also goes to show two things. That there is an exception to every rule and we don’t know as much as we like to think we do. Meet the Comical Opah, the Only Truly Warm-Blooded Fish...

Shark Finning Shark Finning
LiveBait - 23 days 4 hours ago.
In a statistical report about illegal shark killings, about 100 million of these majestic marine animals are killed each year. The study was compiled by the Dalhousie University in Halifax, Canada led by Boris Worm. In his study, it reveals an alarming rate of 6.4 to 7.9 percent of all shark species being killed annually. The report is indeed alarming because it is a number that will lead to the full extinction of sharks if no proper actions will be done to stop the killings.

Jill Heinerth recently published "Women Underwater" The Comprehensive Guide for Women in Scuba Diving. Jill is a remarkable explorer and diver leading the way for women through her adventures around the world above and below the surface. I recommend this book, co-authored by Renee Power to all divers. It is an excellent resource; helping women gain insights into recreational, technical and professional diving, and helping male instructors and dive buddies better understand the unique aspects of ...
Learning to freedive: Part 1 Learning to freedive: Part 1
ArgentAqua - 27 days 13 hours ago.
Taking a Freediving course: Part 1 – the pool sessions. I love Scuba diving, but there are times I could do without climbing into the dry suit, under suit, five-hosed regs, steel tanks, torch, and all the other paraphernalia - including 12kgs of lead - that goes with the cold water diving available to me here in the UK, so, unsurprisingly, I have often been tempted by the apparent pure simplicity of freediving. Unlike America or the Mediterranean there is no real tradition of spearfishing here i...
PADI very distinctive specialties
diver_ralph - 4/15/2015 8:12 AM
Padi lists some of the following specialities on their website: I am interesting in finding the appropriate dive shop whereever it is to see if its worth trying for some of these additional certifications. Anyway, when I search myself online I can’t get a good hit finding the dive shop. Does anyone know where each or any of those distinctive specialites are located (web address) and post them? Thanks for any information you can provide...
Is it ok to pee in the ocean? Is it ok to pee in the ocean?
Greg - 4/14/2015 6:06 AM
Urine is 95 percent water with sodium and chloride ions. But urine contains something the ocean does not; urea. Urea is a water-soluble organic compound that helps the body rid itself of nitrogen. When urine and ocean water combine, the nitrogen in urea produces ammonium and acts as food for the ocean’s plant life. So go for it, you’re helping to save the ocean!...
Quote from Wesley C. Skiles on Extreme Cave Diving Quote from Wesley C. Skiles on Extreme Cave Diving
Greg - 4/04/2015 9:26 PM
I watched a show on Nova today called Extreme Cave Diving. Wes Skiles was the underwater videographer. I really liked what he said towards the end of the show: "You know I’m not sure how to go on in life if I wasn’t able to go to my church underwater. We go down in these places and we’re cleansed. When we come up from a dive...the pressure, the challenges, the difficulties, the conflicts...they’re gone. We come up from a dive and it is like, you’re reborn."...
Freediving and Deaths in Competitions Freediving and Deaths in Competitions
h2oman - 3/20/2015 10:05 AM
Many divers are adventurous souls. We like to eat some fish fillets after our long day on the water, trade some tall tails and plan the next outing. Sometimes we are frustrated when we can’t find anyone to dive with; sometimes we plan an outing and it seems like we have too many people on the boat, or that we invited just 1-2 too many divers. Some of us are very social when it comes to our dive time; we use scuba or freediving as a way to meet people and spend quality time with our friends. At t...

2014 Market Share of Scuba Certification Agencies (PADI, SSI, NAUI)
Greg - 12/12/2014 9:00 AM
According to the certifications added by scuba divers on, the following list indicates the percentage market share by each certification agency. I included all types of certifications, not just entry level certs. This data was collected from 21,273 divers. In the following list, I counted only once per agency per diver (ie: if a diver has 3 PADI certs and 1 DAN cert, I counted 1 for PADI and 1 for DAN): Worldwide 1. PADI: 55.6% (54.9% USA, 60.6% Outside USA) 2. SSI: 10.6% (11.4% US...

Here is some tips for the new diver. During my course I have seen people sign up for scuba for maybe a honeymoon or one trip. Folks this is not a one time commitment. This is a very important step in your life. When you do decide to embark on this journey. Enjoy every aspect of your experiences: whether they be in the class room, at a scuba park, at a lake, or ocean. Be sure to complete and read everything the instructor gives you. Practice your navigation on land. I like to go to the local foot...

Selecting a Training Facility
RAWalker - 8/16/2014 11:39 PM
Considerations for Selection of a Scuba Training Facility The sport of Scuba Diving has maintained a great record of safety while maturing from an elite sport to one that today enjoyed by the masses. This in spite of the fact that it is a high risk sport which allows people to enjoy a hostile environment. Those seeking to engage in the sport should not consider it lightly but with a serious understanding that it requires a great deal of knowledge and training to mitigate the risks and maintain s...
Kayak Diving in South Florida Kayak Diving in South Florida
kayakdan - 7/12/2014 6:39 AM
A kayak can help you reach dive sites as far as 2 miles offshore. They also are great exercise and expand the adventure of diving. Most dive sites in Broward County are within a 30 minute paddle of a kayak launch point. Necessary equipment includes the kayak (about $500), a paddle (about $45) and a coastguard-approved life vest (as cheap as $8). You will also need a dive flag mounted to the kayak ($10) and a lead line ($15 to $30) to pull the kayak along with you during your dive. Optional equip...
The True Cost of Scuba Diving The True Cost of Scuba Diving
Diver96 - 6/30/2014 4:51 PM
There are a lot of excuses for not becoming a diver. Number one on list is the time required to get certified. The second runner-up is that diving is expensive. These are common objections that I often run into. Cost seems to be the major sticking point, or is it? Diving is not cheap, but most adventure pursuits are not. In many places diving has taken on a status more in-line with "yachting" or "sky diving" than a something just about anyone participate in. Is this perception keeping potential ...
NITROX FOR Beginners
YKoach - 6/18/2014 9:02 AM
Although nitrox has been used for recreational diving for almost 25 years, it is still often misunderstood. As an instructor, I’ve found myself correcting countless students who are under the impression that nitrox enables a person to dive deeper than normal air — just one of the common misconceptions about nitrox diving. Although specific training is required before diving nitrox for the first time, these basic facts will help to make more sense of what it is and what it can do for you. What Is...
