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.

They are oviparous and form distinct pairs when mating. They can reach a maximum total length of 10 centimetres (4 inches). Leaping blenny The leaping blenny ("Alticus saliens"), also known
