Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi anali molli: 13 - 16; Vertebre: 43 - 44. Distinguished from other species of Rhamdia by the combination of the following characters: reduced body pigmentation; eyes rudimentary, covered by skin and not visible externally; head length 24.6-27.1% SL; pectoral-fin length 14.4-17.5% SL; maxillary barbel length 39.2-47.3% SL; caudal-peduncle depth 9.3-12.2% SL; pectoral spine serrated on posterior edge only, anterior edge smooth (Ref. 52912).

A troglobitic species (Ref. 52912).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00463 - 0.01496), b=2.97 (2.82 - 3.12), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
