Description

The colonies of Oculina have a straggly branching structure and are mostly pale yellow. The branches are slim, not exceeding 1 centimetre (0.4 in) in diameter. The corallites which house the polyps are widely separated. Their walls are composed of fragile, solid-walled tubes. Each corallite has 12 primary septa with fine teeth which partially project from the corallite wall and which are larger than the intermediate septa. Some species contain symbiotic microalgae called zooxanthellae.[2]
