Notes: Bright orange yellow crumbly masses filling crevices or growing below laminar corals; oscules and skin tend to be transparent. Bahamas specimens have as megasclere spicules strongyles instead of styles-subtylostyles of other areas; sometimes there are completely white specimens that nevertheless have been confirmed to belong to this species (data from Loh et al., 2010).
