Same Genus
Distribution
Temperate Australasia
Description
Small size, long fringed tentacles over the eye, and a fine stippling of dots across the body. The Tasmanian blenny is very common in sheltered habitats along the southeastern coast, where it makes a home in small rock crevices, shells or discarded bottles and cans. During the spawning season females guard clusters of eggs, which are attached to the sides of their nests.

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Frequent (10.2% 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: Few (4 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
