Green Anemone

Aulactinia veratra

Description:

The anemone (pic 1) was about 50 mm with tentacles extended and floating in the water. Tentacles were numerous, translucent but dark green in colour and had pointy ends. The oral disc was covered by sand and therefore not visible.
Where the anemones were out of water, they looked like dark clumps studded with sand grains. Partially submerged anemones (pic 3) 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.

Habitat:

Spotted in rock pools - rocky intertidal zone (Cape Conran)
Occurrence record:

Notes:

The number and arrangement of tentacles is important for identification. This family of anemones (Actiniidae) does not share a symbiotic relationship with fish as some others do.
The anemone feeds on small creatures brought in by the tide, capturing them with its tentacles and transferring the food to the mouth in the centre of the oral disc.
They are mostly bottle green in colour but depth of colour might vary as in this spotting:
