Occurrence of the Oculinidae

The Oculinidae are a family of hard corals (Scleractinia), which mainly contains genera from cold and temperate seas.

The corals mostly live at greater depths and are typical of ahermata, that is, they do not live in symbiosis with zooxanthellae .

Madrepora oculata forms sticks up to 40 centimeters high and lives, for example, off the coast and in the fjords of Norway at depths of 50 to 1600 meters. It is also found in the Mediterranean .

In contrast to warm water corals, cold water corals hardly need any light. They have only been researched since the 1990s and are threatened by ocean acidification and trawling . In 60–70 years, around two thirds of the known cold water corals will no longer exist.
