Tubastraea diaphana

Tubastraea diaphana is a coral species found in tropical regions, particularly in the Pacific Ocean. It is associated with reef environments and can be found at depths ranging from 8 to 54 meters. This coral often inhabits caves and areas beneath rock overhangs, providing a unique sight for divers exploring these darker, sheltered spots. The colonies of Tubastraea diaphana exhibit a range of colors, from dark green and dark brown to black, making them distinguishable from other coral species that may have brighter hues. During a dive, encountering Tubastraea diaphana can be an intriguing experience due to its habitat preferences. Divers might spot these corals in both shallow and deeper waters, and they are often observed in the company of nudibranchs, such as Aeolidiella species, which graze on them. The life cycle of this coral involves a planktonic planula larva stage, which eventually settles and undergoes metamorphosis, forming tentacles and other structures characteristic of mature corals. However, it is included in CITES Appendix II.
