Similar Species

Distribution

Temperate Australasia


Description

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.


Information

Max Size: 21 cm

Sea Temperature Range: 11.6-22.1°C

Depth: 3-30m

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: Infrequent (7.8% 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.
