“…Meristic ranges for New Zealand blennies approximated those presented by Springer & Gomon (1975) for O. anolius, though for most characters the range of variation was narrower and frequency of modal values higher. No differences in coloration or general morphology were observed.…”

“…Current perceptions of the Australian distribution of O. anolius differ from the geographic range presented in Springer & Gomon (1975) only in that the species is now known to occur slightly farther north on the eastern coast of Queensland (Gladstone, 23°48'S, 151°16Ti -AMS I.20400-002) and to reach southward to Narooma, New South Wales (36°14'S, 149°46Ti -AMS I.40460-009). The species is documented north of the above-mentioned Queensland record only from a single collection made in 1914 at Norman River in the southern Gulf of Carpentaria.…”

“…Excluding the two specimens collected by KT (which were not examined by us), there were 9 males, 12 females, and 1 immature blenny (16 mm total length (TL)). Males were distinguished from females by the presence of a large crest on the head and elongated fin rays in the second dorsal fin (Springer & Gomon 1975;Gomon et al 1994;Randall et al 1997;Kuiter 2000;Fig. 3). On two occasions a male-female pair was found under the same boulder.…”

“…The fish were tentatively identified as an Australian species, the oyster blenny Omobranchus anolius (Valenciennes, in Cuvier & Valenciennes, 1836). Apart from one dubious 1864 record from New Zealand, and another pre-1863 record from Bombay, India, this species is considered as an Australian endemic (Springer & Gomon 1975). Therefore its presence in New Zealand may result from a human-assisted introduction, and may pose a biosecurity risk.…”

Twenty-four blennies collected in east Auckland, New Zealand, were identified as the Australian oyster blenny, Omobranchus anolius using taxonomic and molecular characters. This species appears to have been introduced recently to New Zealand. Auckland oyster blennies mainly inhabited dead oyster shells in water pooled under intertidal boulders on mudflats. Specimens ranged from small juveniles to large mature males, suggesting that the species is breeding in New Zealand, or that there have been multiple incursion events. Oyster blennies may be capable of colonising estuaries throughout the northern North Island, and possibly farther south. Control or eradication of O. anolius would be facilitated by its intertidal habitat, lack of an escape response when found, and the very limited movement and natural dispersal of adults and larvae.
