Summary:
A semitransparent greenish, brownish or purplish shore eel with the internal organs usually clearly visible, a row of brownish or greenish blotches along the dorsal fin, sometimes a dark internal midlateral stripe, and a spotted or unspotted head. Males are more colourful with a pattern of regular reddish to brownish tiger-like bars along the side that do not merge with a series of 3-4 blackish to dark blue blotches or bars on the orange abdomen.

More Info


Distribution

Endemic to southeastern Australia, from Point Cartwright, southern Queensland, to Flinders Island, South Australia, including coastal Tasmania. Inhabits seagrass beds and 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; lchrymal pores present; 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 anteriorly along side, continued on body in larger individuals, and not merging ventrally with a longitudinal series of 4 blackish to dark blue blotches or bars on the side of the abdomen, area of blotches extending about halfway between gill slit and urogenital opening.

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 very similar to the Dwarf Shore Eel, Alabes hoesei. The two species can only reliably be separated based on the number of post-ocular pores (= cephalic lateral line canal pores behind the eye), with Alabes parvula having a single pore, and A. hoesei having two pores. 

Etymology

The specific name is from the Latin parvulus (= very small) in reference to the small size of this species.
