Etymology: Micrognathus: Greek, mikros = small + greek, gnathos = jaw (Ref. 45335); brevicorpus: Name from the Latin 'brevis' meaning short and 'corpus' for trunk; referring to its relatively short trunk with low number of trunk rings. More on author: Fricke.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00039 (0.00017 - 0.00089), b=3.16 (2.97 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
