I just returned from a 10 day trip aboard the Undersea Hunter (Scuba Diving Cocos Island Malpelo Liveaboard Cruises Costa Rica) to Cocos Island. What a great trip! We had tons of hammerheads as well as whitetip reef sharks, silkies, Galapagos sharks, and a tiger shark. The last day we even had a whale shark spend about 20 minutes with us at Alcyone. Here are a few photos. Thanks go to Ethan Gordon (Ethan Gordon - Underwater Photography, Destination & Fishing Images) for the shot of the whale shark with my wife.
