This closeup shows the individual polyps lining the rows. A small majid crab has climbed aboard, and may be nipping at the polyps, though the crab's activity did not stimulate Ptilosarcus to close.
Buds seem to be growing off 3 of the laminae on the right side of the plume of this individual. Does Ptilosarcus do any budding for reproduction? Photo by Dave Cowles, July 2005
