Oculina diffusa, commonly known as the diffuse ivory bush coral or ivory tree coral, is found in the eastern Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea. It is found in shallow water, usually down to 3 metres (9.8 ft) deep but occasionally as deep as 20 metres (66 ft). Its colonies are dense and have a yellow-brown color. It favours areas with high amounts of sedimentation.
