Green Snakelock Anemone (Aulactinia veratra)

This anemone is similar to the one in the previous spotting and was found in the same rock pool.
Where the anemones were out of water, they looked like dark clumps studded with sand grains. Partially submerged anemones were interesting in that the submerged part had extended tentacles and the exposed part was curled up displaying a sand encrusted column. Long striations could be seen in the retracted column which was the same colour as the tentacles.
The species has several synonyms, Cnidopus verater is one of them.
