Etymology: Hypostomus: Greek, hypo = under + Greek, stoma = mouth (Ref. 45335); sculpodon: From the Latin sculpo (to carve, cut, grave, or chisel in stone, brass, or wood) and from the Greek odon (tooth) in reference to the ability of the species to chisel wood with the teeth.

Short description Identification keys | Morphology | Morphometrics

Distinguished from all other members of the Hypostomus cochliodon group except H. hemicochliodon by having a buccal papilla and intermediately developed teeth (juveniles of H. cochliodon and H. taphorni occasionally also have intermediate teeth). Differs from H. hemicochliodon by having brownish-red coloration with widely spaced spots vs. dark brown with closely spaced spots, by having a smaller dorsal-anal length to anal-fin length ratio (average=79.2%, 69.6-89.7% vs. average=111.1%, 92.5-132.6%) and almost completely by having a smaller interorbital width/HL ratio (average=51.4%, 38.5-45.4% vs. average=49.9%, 44.1-55.6%) (Ref. 50589).

Facultative air-breathing in the genus (Ref. 126274)

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=0.01622 (0.00733 - 0.03589), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
