The Säcken Reef in the Swedish marine protection of Koster Fjord is an ancient cold water coral reef and the only known coral reef in the country. The Tisler Reef in the Norwegian marine protection of Ytre Hvaler National Park is the largest known coral reef in Europe. Lophelia reefs are also present in the Norwegian trench and they are known ...
Lophelia pertusa is a reef building, deep water coral, but it does not contain zooxanthellae, the symbiotic algae which lives inside most tropical reef building corals. [6] Lophelia lives at a temperature range from about 4–12 °C (39–54 °F) and at depths between 80 metres (260 ft) and over 3,000 metres (9,800 ft), but most commonly at ...
Deep-water coral Paragorgia arborea and a Coryphaenoides fish at a depth of 1,255 m (4,117 ft) on the Davidson Seamount. The habitat of deep-water corals, also known as cold-water corals, extends to deeper, darker parts of the oceans than tropical corals, ranging from near the surface to the abyss, beyond 2,000 metres (6,600 ft) where water temperatures may be as cold as 4 °C (39 °F).
The series took almost five years to make, involving nearly 200 filming locations. The fact that most of the ocean environment remains a mystery presented the production team with many challenges. Besides witnessing some animal behaviours for the first time, the crew also observed some that were new to science.
The Rost Reef (Norwegian: Røstrevet) is a deep-water coral reef off the coast of the Lofoten islands in Nordland county, Norway. The reef was discovered in 2002, about 100 kilometres (62 mi) west of the island of Røstlandet. It extends over a length of about 43 kilometers (27 mi), and has a width of up to 6.9 kilometers (4.3 mi). [1]
The Miami Terrace Reef 1] is a coral reef off the coast of Florida stretching from South Miami to Boca Raton, in the Atlantic It lies in depths of 650 to 2,000 feet (200 to 610 m) on top of a geological formation known as the Miami Terrace, a 40-mile (65 km) long shelf about 15 miles (24 km) off shore.

The reef drop-off is, for its first 50 m, habitat for reef fish who find shelter on the cliff face and plankton in the water nearby. The drop-off zone applies mainly to the reefs surrounding oceanic islands and atolls. The reef face is the zone above the reef floor or the reef drop-off. This zone is often the reef's most diverse area.
The sea is the habitat of over 1,000 invertebrate species and 200 soft and hard corals and is the world's most northern tropical sea. The Red Sea is a rich and diverse ecosystem . More than 1100 species of fish [ 33 ] have been recorded in the Red Sea, and around 10% of these are found nowhere else. [ 34 ]
