The tabulae are usually not crowded, have a smooth, outwardly rounded appearance and decrease rapidly in size away from the central body region.

Note: although the species Nectria multispina is still accepted by the World Register of Marine Species (WoRMS), investigation reveals that there is no confirmation that it differs from N pedicelligera. Thus RLS survey data recorded as N multispina is ported in the RLS database as N pedicelligera.

• IUCN Threat Status: Not Evaluated
• Occurrence: Common (24% 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.
