Body deep and compressed; caudal peduncle long, extremely slender; fins falcate; caudal fin large, forked; angle along anal fin base continues along upper edge of caudal fin. Large-sized individuals possess large, nearly scaleless hump behind small, depressed head; mouth subterminal, extending to front of small eye; 73-90 scales on lateral line; usually 9 dorsal rays; 10 anal rays; pharyngeal teeth 2,5-4.2.

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00441 - 0.02856), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 2.0 ±0.2 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
