''Savalia savaglia'', the gold coral, is a species of colonial false black coral in the family Parazoanthidae. It is native to the northeastern Atlantic Ocean and the Mediterranean Sea where it often grows in association with a gorgonian. It is extremely long-lived, with a lifespan of 2,700 years, and develops into a large tree-like colony. ==Description== ''Savalia savaglia'' forms a large, tree-like colony. The polyps secrete a horny brown or black skeleton from which they project. They are yellow and about tall. Each polyp has an oral disc at the top surrounded by about thirty tentacles. These are arranged in two whorls and are not pinnate, making it easy to recognise that this species is a zoanthid rather than an octocoral or a member of another order of Hexacorallia.〔
