Actinopterygii (ray-finned fishes) > Siluriformes (Catfish) > Pimelodidae (Long-whiskered catfishes)
Etymology: Pimelodus: Greek, pimele = fat + Greek, odous = teeth (Ref. 45335);  halisodous: Derived from the Greek adjective 'halis', meaning in crowds, in plenty, sufficient, enough, and the Greek noun 'odous', meaning tooth, in reference to the several irregular rows of conical and slender teeth on each premaxilla.

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; demersal.   Tropical

Max length : 11.1 cm SL male/unsexed; (Ref. 79502)

Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Vertebrae: 41. Differs from all other species of the genus, except Pimelodus jivaro, Pimelodus joannis, Pimelodus ornatus, Pimelodus pictus, and Pimelodus stewarti, by the possession of a dorsal median crest along supraoccipital process; and shorter distance between the posterior nostril and the anterior orbital border (posterior nostril closer to anterior orbital border). Can be separated from Pimelodus jivaro by the shorter maxillary barbel, extending only slightly beyond caudal-fin base (vs. maxillary barbel surpassing total length); from Pimelodus ornatus and Pimelodus pictus by its uniform grayish to yellowish coloration (vs. presence of two bands or dark dots along flanks, respectively); from Pimelodus stewarti and Pimelodus joannis by its longer pectoral-fin spine (20.0-23.5 vs. 15.4-19.6% SL); longer snout (43.1-47.9 vs. 35.8-41.8% HL); and larger number of premaxillary tooth rows (13-16 vs. 5-9) (Ref. 79502).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00330 - 0.02196), b=3.06 (2.84 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (12 of 100) .
