This species is frequently colonized by " Parazoanthus parasiticus ", a colonial anemone, and " Ophiothrix suensonii ", a brittle star.

Sweetings Pond in North Central Eleuthera is recognized as a site of special ecological value, containing, it is estimated, a concentration of Ophiothrix oerstedi brittle stars at up to 434 individuals per square metre, because of the lack of marine predators.
5.
Echinoderms such as the brittle star " Ophiothrix fragilis " are frequently seen with their arms protruding from rock cracks, whilst the starfish " Asterias rubens " and the sea urchins " Echinus esculentus " and " Psammechinus miliaris " occasionally form part of the community, as does the whelk " Buccinum undatum ".

The giant " Marthasterias glacialis " is the most sighted starfish, but other smaller species do exist such as purple " Asterias rubens ", the tiny " Asterina gibbosa " and the exotic-looking " Ophiothrix fragilis " brittle star . " Paracentrotus lividus " is the general urchin locally and has diverse colour varieties including purple, green and pink.
