Feather star | Comanthus trichoptera
Same Genus
Distribution
Temperate Australasia
Description
Variety of colour forms, most notably orange, yellow, purple, white and brown. These colours generally do not vary along the arms, in contrast to the mottled pattern of Comanthus tasmaniae. The central disk of the body generally remains concealed in crevices or under rocks, while the arms are held up in the water column with the pinnules trapping passing plankton.

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Widespread (60.2% 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: Many (44 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
