Oculina

Oculina is a genus of colonial stony coral in the family Oculinidae. These corals are mostly found in the Caribbean Sea, the Gulf of Mexico and Bermuda but some species occur in the eastern Pacific Ocean. They occur at depths down to 1000 metres.

==Description== The colonies of Oculina have a straggly branching structure and are mostly pale yellow. The branches are slim, not exceeding 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.
