Corals and More; Cnidaria

This family includes much of the non-moving marine life admired at Koh Phangan dive sites. Corals soft and hard, anemones, sea pens, hydroids (and jellyfish?)…

A big range including the Hard Corals, Anemones, Corallimorpharians and Zoanthids. They all have tentacles in multiples of six. (2 Albums, 4 Galleries)

Divers and snorkellers beware; these delicate structures pack an unpleasant sting. And it\'s best for Koh Phangan marine life as well as your own comfort not to touch anything! (3 Galleries)

Also known as Alcyonaria, they include Soft, Whip and Fan Corals, plus the Sea Pens. Their corallum has eight tentacles (not in multiples) and their tentacles are feathery, not smooth. (8 Galleries)

Beautiful photo subjects for divers and snorkellers but keep clear if they have tentacles. Not seen so often in Koh Phangan waters. (6 Galleries)

Thankfully they are not common in these waters!

Comb jellys are technically a different phylum from Cnidaria but we have put them here to keep things simple!
