More Info


Distribution

Endemic to southeastern Australia, from Point Cartwright, southern Queensland, to Flinders Island, South Australia, including Tasmania. Inhabits seagrass beds and sometimes adjacent reef areas (including rockpools) in depths to 10 metres.

Features

Caudal fin 4-6; Vertebrae (total) 63-74.
Body very elongate, moderately compressed; head very short; eyes small; mouth small; teeth small; gill opening a small slit on underside of head, its width less than eye diameter; single sensory pore dorso-posterior to each eye. Dorsal, anal and caudal fins continuous, dorsal and anal elongate, without fin rays; pectoral and pelvic fins absent. Head of females more pointed anteriorly than that of the male.

Colour

Body completely transparent with internal organs usually clearly visible; a row of brownish or greenish blotches on dorsal fin; head spotted or unspotted, male usually with a tiger-like pattern of reddish to brownish bars on side, continued on body in larger individuals.

Remarks

Springer & Fraser (1976) considered the Pygmy Shore Eel to occur in Western Australia and Norfolk Island. However, these forms represent the Western Shore Eel, Alabes occidentalis in Western Australia, and Springer's Pygmy Shore Eel, Alabes springeri in Norfolk Island.

Similar Species

The Pygmy Shore Eel is so similar to the Dwarf Shore Eel, Alabes hoesei, that the two may only be separated by microscopic examination.
