Size / Gewicht / Alter
Maturity: Lm ?  range ? - ? cm
Max length : 5.0 cm TL Männchen/unbestimmt; (Ref. 559)
Rückenflossenstacheln (insgesamt) : 7; Rückenflossenweichstrahlen (insgesamt) : 10; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 9. Body similar to gobioid fishes. No scales on body, but with many well-developed pit organs on head and body. The fan-like caudal fin has many procurrent rays. There is a single downward short spine on the preopercular edge, and many dark-brownish pigments on the caudal peduncle.
Sometimes taken by trawl net, and found in the open sea (Ref. 559).
