Etymology: Brachyplatystoma: Greek, brachys, eia = short + Greek, platys = flat + Greek, stoma = mouth (Ref. 45335);  capapretum: The name capapretum is from Portuguese. While seeking information about this undescribed species in Belém, the authors encountered only one person who distinguished the species from the similar "filhote" or "piraiba", B. filamentosum.

Short description Morphology | Morphometrics

This species is distinguished by the following characters of which the first three are unique among the Pimelodidae and the last is unique among the Brachyplatystomatini: jaw teeth dimorphic with mostly fine, densely spaced outer teeth and relatively few (3-6) inner rows of slender, straight, inwardly depressible teeth; juveniles (< 200 mm SL, but some as large as 300 mm SL) marked by bold, large (twice or more times eye diameter) dark brown or gray spots centered above lateral line; ground color in preservative tan to medium brown; adults and juveniles (> ca. 200 mm SL) black to very dark gray or brown dorsally and abruptly countershaded along a horizontal from snout tip to caudal-fin base, especially along posterior half of body just above or at lateral line; ventrally it is plain white to dusky cream; most specimens with light patch anterior to upper lobe of caudal fin; caudal fin of adults is moderately to shallowly forked, lobes broad and nearly equal (Ref. 55106).

Biology     Glossary (e.g. epibenthic)

Collected below 200 m asl in the Amazon mainstream and largest white and black water triburtaries; trawled 10s to 100s m off shore, on mud and sand substrates (Ref. 55106).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00480 - 0.01443), b=3.11 (2.96 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.8 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (48 of 100).
