Temperate Australasia


Yellowish brown humped head, blending into a green body. The species generally remains concealed in crevices during the day and moves about in the open when feeding at night. A second temperate moray eel, the speckled moray Gymnothorax obesus, occurs along the New South Wales coast. This eel is easily distinguished by colour pattern, as it has numerous cream speckles scattered over a brown body. A few tropical moray eels also occasionally occur, but are rarely encountered.


Max Size: 92 cm

Sea Temperature Range: 14.4-24.6°C

Depth: 0-20m

Habitat Generalization Index: 20.84

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: Common (21.0% 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.
