Western Jumping Blenny, Lepidoblennius marmoratus (Macleay, 1878)
The Eastern Jumping Blenny looks similar. The species can be distinguished by the deep incision in the membrane between the last spine of the first dorsal fin and the fist spine of the second dorsal fin (vs unincised membrane in the Eastern Jumping Blenny). In addition, the Western Jumping Blenny has two anal fin spines (vs no anal fin spines in the Eastern Jumping Blenny).
The Western Jumping Blenny is a small fish that lives in very shallow marine waters of South Australia and Western Australia.
The Western Jumping Blenny has a slightly compressed body and a scaleless head with a steep snout profile. It has three separate dorsal fins, a long-based anal fin and large pectoral fins.
The species is usually grey to greenish above, pale below, and has blotches or banding on the sides. There are dark vertical lines on the head and rows of dark spots on the dorsal, caudal and pectoral fins.
Rockpools and intertidal zones.
The Western Jumping Blenny is endemic to Australia. It occurs in temperate marine waters, usually on rocky reefs and intertidal areas, from eastern South Australia to south-western Western Australia.
