Variable in colour and markings, but often yellow-brown or gold. Typical shape and its flabby skin covered by wart-like lumps. The skin is shed in a single piece at regular intervals, an important process for a fish that remains immobile for most of its life, as it prevents the build-up of fouling organisms. It is difficult to detect in its natural habitat because it closely resembles the sponges among which it lives.

• IUCN Threat Status: Not Evaluated
• Occurrence: Infrequent (7% 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.
