More Info


Distribution

Endemic to southern Australia, from just north of Sydney, New South Wales, to the Houtman Abrolhos Islands, Western Australia, and northern and eastern Tasmania. Inhabits dense shallow seagrass beds and adjacent reefs covered in dense brownish macroalgae, at depths to 5 m.

Features

Caudal fin 7-8; Vertebrae (total) 67-71.
Body very elongate, moderately compressed. Head very short; eyes small; mouth small, reaching to below front part of eye; teeth small, single row in each jaw; no spines laterally; gill opening a small slit on underside of head, its width less than eye diameter. Scales and lateral line absent; pair of sensory pores dorsoposterior to each eye. Dorsal, anal and caudal fins continuous, dorsal and anal elongate, without fin rays. Pectoral and pelvic fins absent.

Colour

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 tiger-like pattern of reddish to brownish bars on side, continued on body in larger individuals.

Similar Species

Extremely similar to the Pygmy Shore Eel, Alabes parvula, differing most noticeably in having two post-ocular sensory pores (= cephalic lateral line canal pores behind the eye), vs. a single pore A. parvula, near the dorso-posterior edge of the eye. Also, the Dwarf Shore Eel is generally found in slightly deeper water and tends to be brownish rather than greenish in colour.

Etymology

The species is named in honour of Douglass F. Hoese, of the Australian Museum, Sydney, who provided much of the material for the study.
