Ophiothrix spongicola, Bermagui, NSW, Photo: Andrew Green
Large brittle star with sinuous arms and a general appearance similar to Ophionereis schayeri. However, unlike that species, the disc is covered by short spinelets except on the five paired triangular areas near the ends of the arms (the â€˜radial shieldsâ€™), and each arm segment has 8â€“10 serrated spines, which are as long as the arm width. The banding pattern on the arms, with alternate bands of purple (sometimes blue) edged with yellow and cream/pink, generally also allows the species to be recognised.
Max Size: 30 cm
Sea Temperature Range: 17.1-23.7°C
IUCN Threat Status: Not Evaluated
Occurrence: Widespread (100% of sites)
Occurrence describes how often the species is found on surveys within its distribution.
It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Few (3 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
