Dorsale stekels (totaal) : 0; Anale stekels: 0; Wervels: 171 - 180. Diagnosis: Body snake-like, cylindrical, compressed only along extreme tail tip; anterior nostril tubular, posterior along lower edge of lip; teeth granular to molariform, multiserial bands on jaws and vomer, but sharper on jaws and more pointed in young individuals; median fins not continuous posteriorly; extreme tip of tail stiff and finless; dorsal fin origin about a pectoral fin length behind tips of pectoral fins; lateral line inconspicuous (Ref. 4832).

Found in lagoons and estuaries, entering freshwater and paddy fields (Ref. 7245, 30573). Common in tidal reaches and nearby upstream areas of coastal rivers (Ref. 12693). Lives in holes in the river bottom and bank and actively forages for small fishes at night (Ref. 12693). Reported to spawn in rice-paddies during the rainy season (Ref. 12693). Caught in bag nets and similar gear. Marketed fresh.
