Eleven-armed Sea Star

Coscinasterias calamaria

Description:

The Eleven-armed Sea Star is native to Australia & New Zealand. They can be identified by their most common feature of eleven arms although you might find them with more or less (7-14) depending upon circumstance. Their colour is normally blue (ocassionally brown), with accents of a multitude of colours. The bi-coloured spines may be blue at the base and salmon pink at the tips.

Habitat:

Intertidal rocky shores and coastal waters to a depth of 150 metres.

Notes:

When I showed these photos to my BIL, he told me this was a Crown Of Thorns Sea Star. After doing some research, I feel he's mistaken in his identification and have found this to be an Eleven-armed Sea Star. Could someone confirm this for me please? Thanks, Trudi

You are correct about your ID. Victoria is too cold for the notorious crown of thorns seastar. http://www.projectnoah.org/spottings/170...
