YEAR DIVE CERTIFIED: 1982 AGE WHEN CERTIFIED: 21 DIVE CERTIFICATION LEVEL: Advanced WORDS TO LIVE BY: You may say that I’m a dreamer But I’m not the only one I hope someday you’ll join us And the world will be as one —John Lennon, “Imagine” Biologist and conservationist Randall Arauz has made almost 40 trips to Costa Rica’s Cocos Island in the past 15 years. What he’s learned there has given him his life’s purpose: to stop overfishing and illegal fishing in the Eastern Pacific, using scientific data to try to persuade governments to change policies, thereby protecting the region’s magnificent megafauna for generations to come.

out of the blue

There is a parable about a man who asked a yoga master to teach him, but he was too weak to do a set of exercises. So the master ordered the new student to train in water. Weightlessness would be easier for the body, but it required more discipline of the breath, since it’s impossible to breathe underwater. Andrey Sidersky, a worldfamous yogi from Kiev, Ukraine, came up with a set of exercises in the ’70s that are used today by freedivers and scuba divers. In-water and underwater yoga techniques help practitioners adjust their mind and body before immersion. “We cannot control our heartbeat, but we can breathe arbitrarily, and our bodies can take arbitrary poses. That’s all we have,” Sidersky said. “Our breathing and body position is our only way…

pocillopora (cauliflower coral)

Pocillopora can be found all over the world. It is a hardy coral species with small bumpy corallites that cover the surface of small knobby branches. Most divers will recognize this coral by its bright-pink color, but Pocillopora that are purple, yellow or cream colored can also be found. This coral can be influenced by the habitat in which it’s found. On reeftops, where you find lots of light and high current, the colonies are compact with short branches. As you dive deeper, the colonies are more spread out, and the branches become flatter so they can capture more light. Pocillopora can adapt to water with low salinity, fluctuations in pH, and coral bleaching events using a survival mechanism called polyp bailout. When this coral is stressed, individual surviving polyps…
