Aquarius is located under 20 m (66 ft) of water at the base of a coral reef within the Florida Keys National Marine Sanctuary, an ideal site for studying the health of sensitive coral reefs. The laboratory is most often used by marine biologists for whom Aquarius acts as home base as they study the coral reef, the fish and aquatic plants that ...

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 site is an excellent example of a pristine coral reef with a spectacular 100-m perpendicular wall, extensive lagoons and two coral islands. [3] In 1999, Ramsar listed Tubbataha as one of the wetlands of international importance. [4] In 2008, the reef was nominated at New7Wonders of Nature. [5]
