Short description Identification keys | Morphology | Morphometrics

Differs from all other Chaetostoma by the combination of the following characters: presence of a dermal keel on the posterior tip of the supraoccipital; reduced number of invertible odontodes (2-5) in the interopercular region; and the presence of three smooth, large, digitiform papillate projections in the buccal cavity (Ref. 26719).

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=0.01585 (0.00685 - 0.03669), b=2.97 (2.80 - 3.14), 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 (11 of 100).
