Daisy Brittle Star (Ophiopholis aculeata), Knobby Coralline-crust Alga (Lithothamnion graciale) discovered by Elijah (#9867)

Comments:

Several rhodoliths (subspherical growths of coralline algae) were washed up, bleached from exposure. Upon splitting one rhodolith, I found that a brittle star had apparently moved into the growth when it could fit inside, only to be entombed when the algal growth washed up. A few tiny and unidentified clams suffered the same entombment.

great sighting. This is Common in Coralline Algae.

Is this species found in Random Island? I've only seen the flat variety there on rocks.

there are several species of brittle stars. I am not sure which ones are found where. I have seen these general types many times in the large amounts of Coralline Algae found in this area.
