Etymology: Lentipes: Latin, lens, lentis = slow + Latin, pes = foot (Ref. 45335); dimetrodon: Named for the extinct reptile genus Dimetrodon of the early Permian; referring to the erect dorsal fins in males and the threatening appearance of the false eye on the first dorsal fin, giving it a much more formidable appearance; noun in apposition.

Morphology | Morphometrics
soft rays: 10. This species is distinguished by the following characters: absence of pore D; often 15 (15-16) pectoral rays; first dorsal fin spines flex posteriorly only slightly at tips in males, the 6th spine is the longest; males with a large spot medially on first dorsal fin and have blackish caudal peduncle (vs. whitish in females) both jawa with conical teeth in males and only on lower jaw in females (Ref. 39342).
Found in swift, clear mountain stream, above several waterfalls, with rocky and boulder-strewn bottom, together with Stiphodon birdsong, several species of Sicyopterus and S. mystax (Ref. 39342).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [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
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
