Maturity: Lm ?, range 14 - ? cm
Max length : 35.0 cm SL male/unsexed; (Ref. 35388); common length : 14.0 cm TL male/unsexed; (Ref. 3397); max. reported age: 14 years (Ref. 32766)
(total): 0. Upper eye less than its own diameter from dorsal profile of head. Anterior nostril on blind side not enlarged, its distance from front margin of head about twice in its distance from cleft of mouth. Anterior nostril on eyed side with backward-pointing tube reaching to front border of lower eye. Pectoral fin on eyed-side small, on blind side reduced.
Inhabits mud or sand bottoms. Feeds on a wide range of small bottom-living organisms, mainly crustaceans (amphipods, shrimps), also polychaete worms and bivalve mollusks (Ref. 4710). Utilized as a food fish.
