This is a colony of little anemone-like creatures that were abundant hanging off the side of the docks at the boat marina. I think they may be Epizoanthus scotinus or Orange Zoanthids? Each was about 3/4" to 1" diameter, and one colony had over a hundred. I waved a pole near them and they closed up tight, like anemones would do.
Anthozoa is a class within the phylum Cnidaria. Unlike other cnidarians, anthozoans do not have a medusa stage in their development. Instead, they release sperm and eggs that form a planula, which attaches to some substrate on which the cnidarian grows. Some anthozoans can also reproduce asexually through budding. More than 6,100 species have been described.
