Coral reefs are the largest living structure on the planet, and the only living structure to be visible from space. As we currently know them, coral reefs have evolved on earth over the past 200 to 300 million years, and over this evolutionary history, perhaps the most unique feature of corals is the highly evolved form of symbiosis. So, I bought a book called The Rugose Coral Genera by Geoffrey Cotton (1973) and it does an excellent job of giving a short description of what looks like thousands of different rugose corals (both colonial and solitary).

Understanding the Context

Here is my original list of five filled out and corrected with information from the book. The Gulf of Mannar’s coral reefs are vital for marine biodiversity, coastal protection, and the livelihoods of thousands of fisherfolk. Continued conservation and adaptive management are essential to ensure their survival amidst escalating climatic and human pressures. Read the full report and summary here.

Coral reefs of the Gulf of Mannar, Tamil Nadu, India - Decadal changes ... Forty-four per cent of reef-building coral species globally are at risk of extinction, the IUCN Red List of Threatened Species (TM) reveals following a global assessment announced today at the ongoing COP29 UN climate conference in Azerbaijan.

I was gifted two specimens of Agatized coral from the Withlacoochee River from a wonderful forum member I had the privilege of hunting with. They are displayed in my living room and receive compliments from many visitors.

Final Thoughts

Coral reef restoration for coastal protection is an area of active multi-disciplinary research and development that will require an array of subject matter experts and the performance of numerous studies and pilot projects to demonstrate feasibility and proof of concept [12-15]. The coral branches and corallite sizes seem way too large for Madracis auretenra which leaves us with the genus Oculina. The branch thickness is too thick for O. tenella (Delicate Ivory Bush Coral) and O. diffusa (Diffuse Ivory Bush Coral). The species O.

arbuscul a (Tube Coral) is more densely branched clumps without longer branches.
