Australian blenny Australian blenny The Australian blenny ("Ecsenius australianus") are small marine blennioid fish of the genus "Ecsenius". They are small and reddish brown with a white ventral side. Australian blennies inhabit the shallow marine waters of the tropics. They are often found along the Great Barrier Reef and Coral Sea of Australia. This species is believed to be most closely related to "E. fourmanoiri". Similarities between these two species include "broad, darkly dusky bands and stripes" and "dark opercular margin[s]", which are not found in other members of the "Opsifrontalis Group". Preserved specimens also bear similarity to "E. opsifrontalis". However, "E.
Pacific leaping blenny members of "A. arnoldorum" are able to thrive on land due to their ability to twist their tails axially at 90 degrees, to propel their bodies. Hsieh noted that the twisting of the tail was a behaviourism unique to "A. arnoldorum" and species in the genus "Andamia"; the two genera were subsequently considered terrestrial. Pacific leaping blenny The Pacific leaping blenny ("Alticus arnoldorum"), also known as the leaping rockskipper, is a species of combtooth blenny (family Blenniidae) in the genus "Alticus". The blennies are oviparous, and form distinct pairs when mating. Males can reach a maximum total length of 8
