Pallenopsis gippslandiae


Temperate Australasia


Large, thin-legged pycnogonid with prominent spines on the legs. The illustrated pycnogonid and similar animals that occur on shallow southern Tasmanian reefs are likely to be this species, although there is a slight doubt about their identity, because the original scientific description of P. gippslandiae was poor and based on deep-water (>60 m) specimens.


Max Size: 5 cm

Sea Temperature Range: 13-19.6°C

Depth: 6-555m

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 (14.3% 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.
