The underwater world is a fascinating ecosystem full of life and variation. This tropical coral reef is covered in Magnificent Sea Anemone’s (Heteractis magnifica) which in turn support Skunk Anemone fish (Amphiprion akallopisos). Above the reef is a massive bait ball of Glass fish which in turn becomes prey to larger fish out in the clear blue water. A perfect demonstration of Nature’s food chain within a healthy ecosystem. Footage taken whilst scuba diving at Koh Haa islands, Krabi province, which is one of Thailand’s best eco tourism destinations.

The Red Sea is a rich and diverse ecosystem. More than 1200 species of fish have been recorded in the Red Sea, and around 10% of these are found nowhere else. This also includes 42 species of deepwater fish. The rich diversity is in part due to the 2,000 km (1,240 mi) of coral reef extending along its coastline; these fringing reefs are 5000–7000 years old and are largely formed of stony acropora and porites corals. The reefs form platforms and sometimes lagoons along the coast and occasional other features such as cylinders (such as the Blue Hole (Red Sea) at Dahab). These coastal reefs are also visited by pelagic species of Red Sea fish, including some of the 44 species of shark.

Indian Ocean oriental sweetlips on coral reef - Maldives (South Ari Atoll).The Indian Ocean oriental sweetlips (Plectorhinchus vittatus) is a species of grunt native to the Indian Ocean and the western Pacific Ocean. This species can be found on both coral and rock reefs at depths from 2 to 25 m.

Underwater close-up footage of a red Gorgonian Sea Fan on a coral reef. Coral reefs are the one of earths most complex ecosystems, containing over 800 species of corals and one million animal and plant species. Coral reefs are currently suffering from rising sea temperatures caused by Global Warming. The water is clear blue in this example of a fragile ecosystem. This image was taken whilst Scuba Diving at Phi Phi, Andaman Sea, Krabi, Thailand.

This rare Critically Endangered Hawksbill Sea Turtle (Eretmochelys imbricata) footage was captured whilst scuba diving at Phi Phi islands in the Andaman Sea, Krabi, Thailand. Sea Turtles are reef dwelling creatures who feed mainly on jellyfish and coral. The Hawksbill Turtle, unlike other sea Turtles, feeds predominantly on sponge corals, making it a crucial part of the Coral Reef Ecosystem. Hawksbills are perhaps the most endangered of all sea Turtles being classed as critically endangered on the IUCN red list, due to being hunted for their meat and shell. This footage shows their primal instinctive behavior as they forage for food on the coral reef. Damage to the coral reef can also be seen in the form of coral bleaching and man made impact.

The French angelfish (Pomacanthus paru) is a large angelfish of the family Pomacanthidae, found in the western Atlantic from New York and the Bahamas to Brazil, and also the Gulf of Mexico and the Caribbean, including the Antilles, Roatan, and the eastern Atlantic from around Ascension Island and St. Paul's Rocks, at depths of between 2 and 100 m. Length is up to 41 cm. Hol Chan Marine Reserve is a marine reserve close to Ambergris Caye and Caye Caulker, off the coast of Belize. It covers approximately 18 km² (4,448 acres) of coral reefs, seagrass beds, and mangrove forest. Hol Chan is Mayan for 'little channel'. The Belize Barrier Reef is a series of coral reefs straddling the coast of Belize, roughly 300 meters (980 ft) offshore in the north and 40 kilometers (25 mi) in the south within the country limits. The Belize Barrier Reef is a 300-kilometer (190 mi) long section of the 900-kilometer (560 mi) Mesoamerican Barrier Reef System, which is continuous from Cancún on the north-eastern tip of the Yucatán Peninsula through the Riviera Maya and up to Honduras, making it the second largest coral reef system in the world after the Great Barrier Reef in Australia. It is Belize's top tourist destination, popular for scuba diving and snorkeling and attracting almost half of its 260,000 visitors.

The devastating effects of coral bleaching as a result of Climate Change, pollution, ocean acidification and over-fishing. These corals are mostly extinct due to the ocean temperature rising and causing loss of endosymbiotic algae. This once was a garden of healthy coral now this coral reef ecosystem is decimated leaving nothing but rubble. One Honeycomb Grouper (Epinephelus merra) tries to find shelter where there is none. Footage taken whilst scuba diving at Phi Phi islands, Krabi province, Thailand.
