The ivory tree coral (Oculina varicosa) can be found in shallow and deep waters. In shallow waters, it is often patchily distributed on coarse shelly reef. However, in deeper water, it can occur as a massive, bush-like aggregation. Oculina reefs typically occur in regions on the shelf edge where water flows upward from depth. It grows very slowly. Their colors range from yellow-brown to lavender. Check our storyboard to learn all about the Ivory Tree Coral.
