Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 80; Afterflossenweichstrahlen: 54. M. jesse differs from all other species of the genus by the following combination of characters: head short, snout blunt, skull length 4.1% TL, rostral fang with dorsal profile slightly convex forming an almost straight line with frontal profile of skull, dorsal fin origin above myomere number 11, anal fin origin below dorsal fin ray number 29, myomeres 104 and jaw with 16 teeth. No lateral, subdermal pigmentation (Ref. 34506).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

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