Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 6. Scorpiodoras liophysus is distinguished from its congeners S. calderonensis and S. heckelii by having a simple, cordiform, gas bladder (vs. gas bladder having a secondary bladder) and midlateral scute depth 61-72% of body depth (vs. 33-59%). It also differs from S. heckelii by having relatively small eye, diameter 58-777% of interorbital width (vs. relatively large eye, diameter 91- 129% of interorbital width) (Rfe. 86601).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [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. 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).
