Dorsale stekels (totaal) : 6; Dorsale zachte stralen (totaal) : 46 - 51; Anale zachte stralen: 40 - 44; Wervels: 28 - 31. This species is distinguished by having spinous pterygiophore formula 3-123, 3-132, or 3-122 + 2. (here the 6th spine shares its interneural space with the 2 pterygiophores associated with the first 2 dorsal fin soft rays) (vs. 3-1221 or 3-12210 in other amblyopines); precaudal vertebrae 9 (vs. 10 ) (Ref. 43739).
Collected over mud and sand bottoms. Its small size and deep-dwelling habitat makes collection a difficult task (Ref. 43739).

50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.

Trofisch niveau (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
