Ask a scuba diver which he would rather see, a seahorse or a shark? The answer may surprise you. Seahorses and pipefish appeal to divers because of their unusual shape and the fact that they are thought to mate for life. Many divers have never seen a seahorse, not because seahorses are extremely rare, but simply because they are very difficult to find. Seahorses and pipefish are masters of camouflage. Still, the photographers featured in this image gallery have not only managed to locate these sneaky creatures, they have captured stunning shots of seahorses and pipefish in their natural environment. Click through this photo gallery to learn more about seahorses and pipefish around the world. Read more.
A diver should be able to use his lungs and his buoyancy compensator (BC) to keep himself neutrally buoyant (or close to neutrally buoyant) during the entire descent. This is important in order to avoid ear problems, environmental contact, and buddy separation. Here are tips to mastering a proper scuba diving descent. Read more.
Read and interview with shark biologist Dr. David Delaney. Dr. David Delaney has dedicated his career to the study and conservation of sharks. I was interested to learn what he thinks about the practice of baited shark dives. Shark feeding on scuba dives can be done by hand, by tossing fish bits in the water from a boat, or by hiding feeder fish in some sort of receptacle which the sharks approach. Read more
Trim is one of the most important (and most overlooked) concepts in scuba diving. A diver's trim refers to his position in the water. A diver in good trim can hold a horizontal position in the water with no hand or fin movements. Trim is affected by arm, leg, and torso position, as well as by body composition and equipment configuration. This article assumes divers already understand the concept of trim in scuba diving, and focuses on how a diver's equipment may be adjusted to correct his trim. Read more
A pair of rounded eyes poked out of the sand. One eye pointed directly at my dive group while the other focused in the opposite direction. I couldn't believe my luck! My dive group was making its way between two coral heads, and I had just spotted a peacock flounder buried beneath the sand. I called my dive group to a halt, and then slowly finned my way closer to the flounder so as not to frighten it away. Read more.
By About.com guest author Julien Borde. Freedivers have no control over buoyancy. According to Boyle's Law, the deeper you dive, the more negatively buoyant you will become. This means that because he does not have a BCD, at some point the freediver begin will sink. Even though a freediver cannot control his buoyancy, with a little training can use the buoyancy shift to his advantage. Read more.
Ten years ago, this was a healthy coral reef. Thankfully, you can help to restore this once thriving ecosystem.
By About.com Guest Author, Stefanie Conrad. Convincing others to be concerned about the health of our coral reefs is challenging. As recreational divers in the tropics, where most coral reefs are found, we pay dive shop operators to take us to the best spots for indulging in the strange and rich diversity of life underwater. It's a paradise that we've escaped to, where we can relax and enjoy peace and quiet surrounded by beautiful vistas. Read more.
