Waratah Anemone or Cherry Anemone

Actinia tenebrosa

This species with its brilliant red tentacles exposed is unmistakable, although when exposed at low tide the tentacles are retracted and the anemone closes up to form small dark brownish-red spheres. They are typically 25-30 mm, but may grow to 40 mm in diameter. They are abundant, attached to rocks in pools, in crevices and to the under side of boulders in the mid to lower intertidal zone; often exposed at low tide. Their young are brooded internally and can sometimes be seen high in the column before they are released.

Their distribution ranges from southern Australia, from Shark Bay, WA, to Heron Island, Queensland, and extends to New Zealand.
