Short description Identification keys | Morphology | Morphometrics

Microglanis oliveirai is readily distinguished from all congeners in the possession of the following characters: short lateral line, reaching only the vertical line through base of dorsal-fin spine; 3-6 lateral line pores; 3-6 gill rakers in the first branchial arch; 10-11 branched caudal fin rays; 5 pleural ribs; 27-28 free vertebrae; large anterior fontanel; small supraoccipital process not contacting anterior nuchal plate; small nuchal shield (Ref. 88956).

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=0.00741 (0.00314 - 0.01747), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
