Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 2; Dorsale zachte stralen (totaal): 7; Anale stekels 1; Anale zachte stralen: 3 - 4. This species is distinguished from all its congeners by having the last dorsal-fin ray adnate with adipose fin via a posterior membrane that extends beyond the preadipose plate up to half the length of the adipose-fin spine (vs. membrane separated from preadipose plate by up to two plates or stopping at preadipose plate); further differs from B. niveatus and B. longipinnis by having a naked abdomen (vs. partially plated), and from B. demantoides by having fewer premaxillary teeth (8-36 vs. 34-54, respectively) (Ref. 80502).

Biologie     Verklarende woordenlijst (bv. epibenthic)

This species is collected from the interstices of granitic bedrock and boulders that constitute exposed portions of the Guyana Shield. Apparently feeds on periphyton and associated microfauna that are abundant on surfaces and undersides of rocks in this habitat (Ref. 80502).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
