Etymology: Protogobiesox: ‘‘ancestral gobiesocid;’’ it refers to the pelvic fins resembling the putative ancestral form of gobiesocids; asymmetricus: Named for the unusual asymmetry of head and body.

Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
duri punggung lunak (Keseluruhan (total)) : 9 - 10; Sirip dubur lunak: 8; vertebrata, bertulang belakang: 34 - 35. Dorsal-fin rays 9-10; anal-fin rays 8; pectoral-fin rays 17-24; principal caudal-fin rays15, gills3, the third arch with 3 gill rakers; total vertebrae 34-35, with asymmetrical lateral bending starting behind the skull, bent at an angle of 85°-92°; asymmetrical skull in frontal view; naked skin, surface of head and body without striae; disc without adhesive papillae; posterior margin may be partially fringed; region B small, left- and right-hand sides separate, larger on the right-hand side than on left-hand side (Ref. 117884).
Found in relatively cool water in an area with temporary upwelling along the northern coast of
Papua New Guinea and in association with sunken logs; its specializations and especially the lateral asymmetry may be useful to be attached to these logs (Ref. 117884).
