Anthothoe albocincta (Family Sagartiidae)

Striped Anemone

Distribution

Distribution:

Anthothoe albocincta has been recorded from Ceduna, South Australia to New South Wales and Tasmania, and from New Zealand. (SA, VIC, NSW, TAS)

Features:

The Striped Anemone is 8 mm high, and up to 15 mm across with the pedal disc being slightly wider than the column. The most distinctive feature of this anemone is the longitudinal stripes on the column. White and dark brown stripes alternate and the upper part of the column is orange. Tentacles are white and unmarked. The oral disc is orange with white stripes around the mouth. There are many (about 200) conical tentacles. The inner tentacles are of moderate length and the outer tentacles are substantially shorter.

Ecology/Way of Life:

This species is common in south-eastern Australian locations, at the lower limits of the intertidal zone under rock ledges and on jetty pylons.

Interaction with Humans/Threats:

No threats are known for this species.

Other Comments:

This species is known to occur in aggregations of individuals all with the same colour pattern. These have been found to be clones formed by asexual reproduction in which an individual adult splits in half to form two individuals. The species also reproduces sexually, producing tiny planktonic larvae, which are dispersed by ocean currents.
