Notolabrus tetricusBlue-throat wrasse | Bluethroat Wrasse | Kelpie
Juveniles are usually mottled brown, but can also be bright green, similar to juveniles of other wrasses, like N. fucicola. A dark bar becomes more obvious in the middle of the body as they grow, and a white bar develops behind this and becomes prominent in males. One of the most common and frequently encountered wrasses in south-eastern Australia, particularly Tasmania.
Max Size: 50 cm
Sea Temperature Range: 10.3-21.7°C
Depth: 1 - 50 m
Habitat Generalization Index: 29.39
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: Least Concern
Occurrence: Widespread (78.4% 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: Several (8 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
