We found this on two occasions during our 2015 trip. Three were exposed on a rock at night at Eagle Point, and seven more exposed on a rock at Koala in the late afternoon.
This species was plentiful on our 2016 trip. Literally hundreds were seen on Briareum at Arthur's, and more were found at Kitchen Rock and a new site near Bethlehem we called Elephant Ear.
Still more were found in 2017 and 2018.
A small crab was nestled among the cerata of one specimen.
This appears to be one that had lost all its cerata and is regrowing them.
