No Limits Freediving
1 No Limits Freediving "The challenges to the respiratory function of the breath-hold diver' are formidable. One has to marvel at the ability of the human body to cope with stresses that far exceed what normal terrestrial life requires." Claes Lundgren, Director, Center for Research and Education in Special Environments A woman in a deeply relaxed state floats in the water next to a diving buoy. She is clad in a figure-hugging wetsuit, a dive computer strapped to her right wrist, and another to her calf. She wears strange form-hugging silicone goggles that distort her eyes, giving her a strange bug-eyed appearance. A couple of meters away, five support divers tread water near a diving platform, watching her perform an elaborate breathing ritual while she hangs onto a metal tube fitted with two crossbars. A few meters below the buoy, we see that the metal tube is in fact a weighted sled attached to a cable descending into the dark-blue water. Her eyes are still closed as she begins performing a series of final inhalations, breathing faster and faster. Photographers on the media boats snap pictures as she performs her final few deep and long hyperventilations, eliminating carbon dioxide from her body. Then, a thumbs-up to her surface crew, a pinch of the nose clip, one final lungful of air, and the woman closes her eyes, wraps her knees around the bottom bar of the sled, releases a brake device, and disappears gracefully beneath the waves. The harsh sounds of the wind and waves suddenly cease and are replaced by the effervescent bubbling of air being released from the regulators of scuba-divers. -
Wild About Learning
WILD ABOUT LEARNING An Interdisciplinary Unit Fostering Discovery Learning Written on a 4th grade reading level, Wild Discoveries: Wacky New Animals, is perfect for every kid who loves wacky animals! With engaging full-color photos throughout, the book draws readers right into the animal action! Wild Discoveries features newly discovered species from around the world--such as the Shocking Pink Dragon and the Green Bomber. These wacky species are organized by region with fun facts about each one's amazing abilities and traits. The book concludes with a special section featuring new species discovered by kids! Heather L. Montgomery writes about science and nature for kids. Her subject matter ranges from snake tongues to snail poop. Heather is an award-winning teacher who uses yuck appeal to engage young minds. During a typical school visit, petrified parts and tree guts inspire reluctant writers and encourage scientific thinking. Heather has a B.S. in Biology and a M.S. in Environmental Education. When she is not writing, you can find her painting her face with mud at the McDowell Environmental Center where she is the Education Coordinator. Heather resides on the Tennessee/Alabama border. Learn more about her ten books at www.HeatherLMontgomery.com. Dear Teachers, Photo by Sonya Sones As I wrote Wild Discoveries: Wacky New Animals, I was astounded by how much I learned. As expected, I learned amazing facts about animals and the process of scientifically describing new species, but my knowledge also grew in subjects such as geography, math and language arts. I have developed this unit to share that learning growth with children. -

DYNAMICS OF ESTUARINE MICROPHYTOBENTHOS IN A SHALLOW WATER SAND BOTTOM HABITAT by Jeffrey Garner Allison B.S., The University of West Florida, 2000 A thesis submitted to the Department of Biology College of Arts and Sciences The University of West Florida In partial fulfillment of the requirements for the degree of Master of Science 2006 The thesis of Jeffrey Garner Allison is approved: Joe E. Lepo, Ph.D., Committee Member Date Jane M. Caffrey, Ph.D., Committee Member Date Richard A. Snyder, Ph.D., Committee Chair Date Accepted for the Department/Division: George L. Stewart, Ph.D., Chair Date Accepted for the College: Jane S. Halonen, Ph.D., Dean Date Accepted for the University: Richard S. Podemski, Ph.D., Dean of Graduate Studies Date ii ACKNOWLEDGMENTS I am grateful for loving, caring, and kind family and friends through which my emotional stability, trust and support was upheld. I would like to thank my major advisor Dr. Snyder as well as my committee members, Dr. Lepo and Dr. Caffrey, for the opportunity to complete a Master of Science in Biology degree. My thesis work would not have been possible without their guidance and lasting direction. Likewise, the support of my colleagues, Matt Wagner, Mike McAllister, Alex Ren, Paige Cramer, Ashley Moore, Kristen Hellein, Joe Moss, Hugo Castillo, Alan Knowles, and Melissa Ederington-Hagy enabled me to accomplish my goals and were instrumental throughout experimentation and analysis. Technical information and assistance was generously provided by Jim Hammond, Jan Macauley, Steve McLin, and Tanya Streeter. I especially appreciate the ability to use the facilities at Gulf Islands National Seashore, thanks to Riley Hoggard and Permit #: GUIS-2005-SCI-003. -
18 Special Habitats and Special Adaptations 395
THE DIVERSITY OF FISHES Dedications: To our parents, for their encouragement of our nascent interest in things biological; To our wives – Judy, Sara, Janice, and RuthEllen – for their patience and understanding during the production of this volume; And to students and lovers of fishes for their efforts toward preserving biodiversity for future generations. Front cover photo: A Leafy Sea Dragon, Phycodurus eques, South Australia. Well camouflaged in their natural, heavily vegetated habitat, Leafy Sea Dragons are closely related to seahorses (Gasterosteiformes: Syngnathidae). “Leafies” are protected by Australian and international law because of their limited distribution, rarity, and popularity in the aquarium trade. Legal collection is highly regulated, limited to one “pregnant” male per year. See Chapters 15, 21, and 26. Photo by D. Hall, www.seaphotos.com. Back cover photos (from top to bottom): A school of Blackfin Barracuda, Sphyraena qenie (Perciformes, Sphyraenidae). Most of the 21 species of barracuda occur in schools, highlighting the observation that predatory as well as prey fishes form aggregations (Chapters 19, 20, 22). Blackfins grow to about 1 m length, display the silvery coloration typical of water column dwellers, and are frequently encountered by divers around Indo-Pacific reefs. Barracudas are fast-start predators (Chapter 8), and the pan-tropical Great Barracuda, Sphyraena barracuda, frequently causes ciguatera fish poisoning among humans (Chapter 25). Longhorn Cowfish, Lactoria cornuta (Tetraodontiformes: Ostraciidae), Papua New Guinea. Slow moving and seemingly awkwardly shaped, the pattern of flattened, curved, and angular trunk areas made possible by the rigid dermal covering provides remarkable lift and stability (Chapter 8). A Silvertip Shark, Carcharhinus albimarginatus (Carcharhiniformes: Carcharhinidae), with a Sharksucker (Echeneis naucrates, Perciformes: Echeneidae) attached. -

Passage A A French professor tells of how he and his friend, and a sailor called Ned, fell into the Pacific Ocean in 1850 when their ship was hit by a huge creature. They at first believed it to be the legendary whale they were searching for on behalf of the International Marine Society. The monster of the deep My first concern was to look for the ship. I glimpsed a black mass disappearing eastward, its lights fading in the distance. I shouted for help, swimming desperately toward the ship. My clothes were weighing me down. I was sinking! Then I found and seized the arm of my loyal friend. ‘What about the ship?’ I asked. ‘As I jumped overboard, I heard the helmsman shout, “Our propeller and rudder are smashed by the monster’s tusk!” ’ ‘Then the ship can no longer steer, and we are done for!’ Having concluded that our sole chance for salvation lay in being picked up by the ship’s longboats, we had to take steps to wait for them as long as possible. -

This is paralleled only by aquatic and semi-aquatic mammals. In all air breathers, the ability to breath-hold dive is set by a number of physiological factors. Some of these have been extensively studied, like the ‘diving response,’ which diverts blood to the brain, heart and working muscles, while less sensitive organs can rely on anaerobic me- tabolism. The diving response is effectively triggered in trained human divers and may reduce the heart rate by 50% – simi- lar to the response in semi-aquatic mammals, and it has been shown to conserve oxygen and prolong apneic duration.
