Dorsal spines (total): 2; Dorsal soft rays (total): 6 - 7; Vertebrae: 34. Scorpiodoras heckelii is diagnosed from its two congeners S. calderonensis and S. liophysus by having a relatively large eye, diameter 91-129% of interorbital width (vs. relatively small eye, diameter 58-93% of interorbital width). It further differs from these congeners by the
having a simple, egg-shaped, secondary bladder without terminal diverticulum (vs. secondary bladder absent in S. liophysus and with terminal diverticulum in S. calderonensis) and from S. liophysus by presenting a relatively shallow scute depth (33-51% of body depth near anal-fin origin, vs. 61-72%) (Ref. 86601).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.3 ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
