Summary:
A very long, slender, greenish-brown worm-like eel with low dorsal and anal fins that barely reach the sharply pointed tail tip, and no pectoral fins.

This nocturnal species uses its bony tail tip to burrow tail first into the sediment, and to probe the sediment for food items such as alpheid shrimps.

Shorthead Worm Eel, Scolecenchelys breviceps (Günther 1876)

More Info


Distribution

Widespread in southern Australia, from about Wallis Lake, New South Wales, to Perth, Western Australia, including Tasmania. Elsewhere, the species occurs in New Zealand.

Buries in soft sediments in estuaries, bays and inshore waters; occasionally trawled offshore at depths to 156 m.

Features

Vertebrae 161-167

Body depth 1.9-2.9% TL; head length 8.0-9.4% TL; snout rounded, lower jaw only slightly shorter than snout; eye moderate, diameter less than interorbital distance, rear margin of eye above or ahead of level of corner of jaw; teeth in two or three irregular rows on jaws and vomer; teeth in an oval patch on "premaxillary", patch joining that of vomer.

Size

To 60 cm TL.

Colour

Greenish-brown above, reaching a line from angle of mouth posteriorly to gill opening and then to anus; markedly darker above lateral midline; chest and anus not notably darkened; much paler below.

Remarks

Digested or "encysted" Shorthead Worm Eels are occassionally taken from the stomachs or even the body cavities of deeper-living fish - the eel having penetrated the stomach wall after being swallowed.

Etymology

The specific name breviceps is from the Latin brevis (= short) and ceps (= head), in reference to the shorter head of this species, compared with that of Muraenichthys macropterus (= Scolecenchelys macropterus).
