Blue Creek reef is named after the tidal pass that divides a tangle of mangroves a distance behind the western reef line. The reefs at Blue Creek are shallow, broken and have abundant and varied marine life. Snorkelers and less experienced divers will find this site very attractive. Live-aboards visiting this site frequently spend the night here and offer this site as a night dive. Much of the marine life at Blue Creek is seen only on night dives. Crabs and lobsters are among the most exciting and interesting nocturnal creatures. Although these arthropods generally forage as individuals, dozens of animals can be found searching for food on the sand flats or coral formations after dark, including spectacular giant spider crabs. If you wish to photograph these invertebrates, you will need a wide-angle lens because their bodies alone are too big for a close-up kit framer. Decorator crabs aren't as large, but they are plentiful, colorful and also active at night. These strange-looking crabs attach a variety of sponges to their bodies, so no two look alike. Look for them on sea fans and sea rods and keep an eye open for large Spanish lobsters. These bizarre creatures like to scrounge for tiny bits food and are most commonly seen sand channel floors. Other invertebrates seen here best photographed at night inch brittle starfish and urchins. Ruby, slimy and Oersted's brittle stars can be tot near the entrance of every little reef, hole, along with Suenson's brittle stars draped over sponges. You will also find an abundance of reef and long-spined black urchins, both of which shun light and do not wander far from shelter even at night. Although only invertebrates are mentioned here, fish watchers will not be disappointed. Blue Creek makes an exciting dive that everyone can enjoy.
