; sötvatten bentopelagisk; djupintervall 30 - 150 m (Ref. 55908), usually 60 - 150 m (Ref. 55908). Tropical; 13°S - 15°S

Könsmognad: Lm ?  range ? - ? cm
Max length : 12.7 cm SL hane/ej könsbestämd; (Ref. 5594)
Taggstrålar i ryggfenan (totalt) : 15 - 16; Mjukstrålar i ryggfenan (totalt) : 9 - 11; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 8 - 9. Diagnosis: cleithrum elongated, forming a clear prominence protruding on the chest, already visible in specimens of 53.0mm SL; sensory pores on the head greatly enlarged (Ref. 55908).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Typical deep-water species, with an even distribution below 60m (Ref. 55908). Found in areas where the bottom consist of diatomaceous ooze (Ref. 5595) but also on sandy habitats (Ref. 55908). Food may consist of invertebrates (Ref. 5595) and perhaps small fishes (Ref. 55463).
