Black and Wire Coral; Antipatharia family

Black and Wire Coral are found in deeper waters at a few Koh Phangan local dive sites. Their living tissue is brightly coloured, but the family takes its name from the distinctive black colour of the corals keratin skeleton.
If you look carefully when diving you will find that wire corals are host to the beautiful Sawblade Shrimp.

Not Giant Hydroids as we previously thought...

Growing where the stronger currents run - sometimes in interesting shapes.

Looking like a skinny underwater bush, in shades of white, yellow and orange.
