Description

Red coral is a slow-growing colonial organism found on rocky walls, caves and overhangs in the Mediterranean Sea. Its skeleton of calcium carbonate is a deep, vivid red that has been prized in jewellery for millennia. Colonies grow just a few millimetres per year, making them extremely vulnerable to harvesting. Today the species is protected across most of its range and listed as Endangered. Divers lucky enough to spot it should admire from a distance and never touch it.
