More Info


Distribution

Endemic to southern Australia, from Broken Bay, New South Wales, to Great Francis Island, Great Australian Bight, South Australia, including around  Tasmania.
Usually shelters under rocks and shells from the intertidal region to a depth of about 10 m.

Features

Caudal fin 7-8; Pelvic fin 3; Vertebrae (total) 66-78.
Body very elongate, relatively robust, moderately compressed (depth 9.3–11.6 in SL); head very short; eyes small; mouth small; gill opening a small slit on underside of head, its length equal to or greater than eye diameter; single post-ocular sensory pore dorso-posterior to eye; dorsal, anal and caudal fins continuous, elongate, without fin rays, dorsal fin relatively high, continued anteriorly as a prominent fin fold to area above urogenital opening (snout to origin of dorsal fin 2.0–3.5 in SL); pelvic fins rudimentary, positioned immediately behind gill opening, width equal to or greater than length of gill slit.

Colour

Large blackish circular blotches often present along the midside of large adults.

Remarks

Seen more often than other shore eel species due to its relatively large size and intertidal habitat. 
Although eel-like in shape, the Common Shore Eel is a member of the clingfish family - the Gobiesocidae.

Similar Species

The similar Elongate Shore Eel, Alabes elongata, has a more slender body, lower fins, and a different colouration.  

Etymology

The specific name is from the Latin dorsalis (= of, or pertaining to the back).
