Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 1; Rückenflossenweichstrahlen (insgesamt) : 6; Afterflossenweichstrahlen: 9 - 12; Wirbelzahl: 30. Distinguished from M. parahybae and M. cibelae by the longer head (29.3-33.8% SL, versus 23.2-27.6 and 25.6-31.1 respectively) and wide body (28.5-33.9% SL versus 23.8-27.7 and 25.4-29.8, respectively). The smaller mouth width distinguish this species from M. eurystoma (50.6-64.3% HL, versus 67.3-84.4).

Reported to reach approximately 9 cm SL (Ref. 81048).

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=0.00603 (0.00303 - 0.01197), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

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