These white pedicellaria distinguish if from the similar Lytechinus williamsi (Jewel Urchin) which has purple pedicellaria. The spines radiate in a spoke like pattern from the centre of the shell in more or less dense wedges.
Max Size: 11 cm
Sea Temperature Range: 27-29.6°C
Habitat Generalization Index: N/A
Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Frequent (12.9% 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: Solitary (1 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
