Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 2; Radios blandos dorsales (total) : 6 - 7; Espinas anales: 1; Radios blandos anales: 5; Vértebra: 28. Can be diagnosed from its congeners by having shorter pectoral-fin spine length (18.6-21.3 vs. 21.4-30.4% SL in remaining species). Additional characters useful for its identification include lower caudal peduncle (7.6-9.0 vs. 9.3-11.0 in Otothyropsis marapoama and 9.7-11.5% SL in Otothyropsis piribebuy), deeper caudal peduncle (7.6-9.0 vs. 6.2-7.6% SL in Otothyropsis polyodon); and dorsal-fin spinelet triangular in shape (vs. spinelet rectangular or quadrangular) (Ref. 93039).
Body shape (shape guide): elongated.

Biología     Glosario (por ej. epibenthic)

Commensal with midge larvae (Chironomidae) which are attached to the gill opening or more rarely to the posterior process of the cleithrum (Ref. 93039).

Estimates based on models

Phylogenetic diversity index (Referencia 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Resiliencia (Referencia 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
