Short description
Identification keys | Morphology | Morphometrics
Ventral surface of the head mostly scaled, except for scaleless areas anterior to the mouth and on the anterior half of the lower jaw. Pelvic fin with 8 rays, rarely 7 or 9. Lower jaw with 2–3 rows of small pointed uniform-sized teeth reducing to a single row posteriorly. Upper jaw with 4–5 rows of small, uniform-sized teeth. Body scales small, 30–40 in a diagonal row from anal fin origin to lateral line. Pyloric caeca 20–37 (Ref. 89100).

50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00214 (0.00109 - 0.00421), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
