Maturité: Lm ? range ? - ? cm
Max length : 400 cm TL mâle / non sexé; (Ref. 3258); common length : 70.0 cm TL mâle / non sexé; (Ref. 3258)
Vertèbres: 183 - 196. Brownish grey above, lighter below (Ref. 3257). Body moderately elongate, cylindrical in front, compressed along tail; eyes small; teeth small, biserial, inner series enlarged; head not obviously distinct from trunk although the profile is moderately steep; very large mouth, extending to well beyond eye; biserial sharp teeth on jaws, larger in front and in inner row; dorsal fin inserted on head before gill-opening; scales absent (Ref. 4832).
Body shape (shape guide): eel-like.
Inhabits muddy ocean bottoms (Ref. 6934) and estuarine areas (Ref. 2334), but sometimes found in rivers (Ref. 2334) and inner bays (Ref. 37816). Feeds mainly on a variety of small fishes and crustaceans. Known to extend itself vertically from a burrow with its head held horizontally beneath the surface, rising and falling with the tide (Ref. 9710). Marketed fresh and consumed locally (Ref. 3258). Solitary (Ref 90102).
