                                                    Mark Strickland’s life-long interest in the sea has included over 10,000 dives and careers as a lifeguard, boat captain, and scuba instructor. His passion for underwater photography has led him to many top dive locales, including the Virgin Islands, Australia, and Thailand, where he spent 17 years as Cruise Director on a series of liveaboards. Mark now resides in Ventura County, California. 

                                                    An avid marine naturalist, Mark has discovered several nudibranch species. He is co-author and principal photographer for Lonely Planet’s award-winning book, “Diving and Snorkeling Thailand”, and his work appears in many magazines, books, and displays around the world. Currently, Mark leads several dive trips each year to his favorite destinations, while working on a career-spanning large-format pictorial book. 

                                                    Mark's photos and articles have appeared in magazines and books around the world, including Action Asia, BBC Wildlife, National Geographic World, Natural History, Scuba Diving, Skin Diver, Sport Diver, Sportdiving, Unterwasser, and many others.

                                                    On par with the Galapagos and Socorro Islands, Cocos Island National Park is aUNESCO World Heritage Centreand a mecca for all things sharky. Diving here typically wouldnt be described as pretty, as there is virtually no colorful coral, and therefore none of the associated vibrant reef species. But dont be fooled - the waters around Cocos are some of the richest in the world, with Pacific Ocean currents converging to bring all manner of shark species, and a myriad of other pelagics to the island.

                                                    We hopped on the shuttle in San Jose and headed out towards the port town of Puntarenas. Traffic was bad due to the long weekend, but we arrived at the boat in great spirits. Our driver was a ornithologist and gave us lectures along the drive about the flora and fauna of Costa Rica. We boarded the Okeanos Aggressor I and motored out of port right away.
