Tubbataha Reefs Natural Park is home to some of the most beautiful coral reefs in the world. Rising from the volcanic depths of the Sulu Sea in the western Philippines, these magnificent atolls encompass an astonishing diversity of marine life.
The park is an underwater sanctuary where nature thrives. Tubbataha is the Philippines' first national marine park and is also a UNESCO World Heritage Site, a place of global importance being preserved for future generations of humankind.
Tubbataha supports an unparalleled variety of marine creatures. Colorful reef fish crowd corals growing in the shallows while sharks and pelagics haunt the steep drop offs to the open sea.
A team of rangers are stationed on the reef year-round and, from March until June, divers visit Tubbataha to experience the wonders of this unique underwater world.
Tubbataha is located in the Sulu Sea, 98 nautical miles (181 km) southeast of Puerto Princesa City in the Palawan Province. The reef is made up of two coral atolls divided by an eight-kilometer (5 miles) wide channel. The South Atoll, the smaller of the two is five kilometers in length and three kilometers in width; while the North Atoll, the larger of the two is 16 kilometers (10 miles) long and five kilometers (3 miles) wide.(Knipp 22) Each reef has a single small islet that protrudes from the water. The atolls are separated by a deep channel 8 km (5 miles) wide.
There are no permanent inhabitants of the islets or reefs. Fishermen visit the area seasonally, establishing shelters on the islets. The park is visited by tourists, particularly divers. Trips to Tubbattaha from mid-March to mid-June are all vessel-based; the park is about twelve hours by boat from Puerto Princesa City. Tubbataha is considered as the best dive site in the Philippines and the diving dedicated ships that operate during the "Tubbataha Season" are usually booked years in advance especially during the Asian holidays of Easter and "Golden Week".
Tubbataha has become a popular site for seasoned sports divers because of its coral "walls" where the shallow coral reef abruptly ends giving way to great depths. These "walls" are not only wonderful diving spots but they are also wonderful habitats for many colonies of fish. There are giant trevally (jacks), hammerhead sharks, barracudas, manta rays, palm-sized Moorish idols, napoleon wrasse, parrotfish, and moray eels living in the sanctuary. There also have been reported sightings of whale sharks and tiger sharks. Tubbataha is even home to the hawksbill sea turtles (Eretmochelys imbricata) which are endangered species
Over 1000 species inhabit in the reef; many are already considered as endangered. Animal species found include manta rays, lionfish[disambiguation needed], sea turtles, clownfish, and sharks.
Vivid corals cover more than two-thirds of the area and the waters around the reef are places of refuge for numerous marine lives. The seemingly diverse ecosystem of this sanctuary rivals the Great Barrier Reef – having 350 coral species and 500 fish species. In June 2009 an outbreak of the crown-of-thorns starfish was observed, possibly affecting the ecological functioning of this relatively pristine coral reef.
Aside from being a marine sanctuary, Tubbataha is also renowned for being a bird sanctuary. A lighthouse islet, at the southern tip of the South Atoll, supports a large number of seabirds which nest there. Around the Tubbataha, there are tens of thousands of masked red-foot boobies, terns, and frigate birds resting during their annual migrations. To minimize any external intrusions, the Philippine Coast Guard maintains a small monitoring station on one of the many permanent sand bars.
