Facts about this animal

The Green Bubble Coral is a stony coral with large polyps. It can grow to 1-2 m and produces a basal calcareous skeleton. Although there are many polyps there is only one large oral opening. The Green Bubble Coral has bubble-like processes next to its tentacles in order to enlarge the surface and to offer more space and light to the symbiotic algae, the so called zooxanthellae which make the bubbles green. These bubbles shrink during night and the tentacles expand to 4-5 cm in order to capture food. The colour is green or blue.

Fertilization takes place in the digestive cavity and the planula larvae are released through the mouth. The larvae settle after one day and soon produce a calcareous basal plate. Within a few weeks tentacles grow.
