Description synthétique Morphologie | Morphométrie

Rayons mous anaux: 9. Lepidomeda molispinis can be distinguished by the following characters: scales on lateral line 77-91; anal fin with 9 rays; pharyngeal teeth 2,5-4,2; rounded snout; large terminal mouth; large males with red-orange at paired and anal fin bases, upper edge of gill cover, sometimes on belly; and opercle with black specks confined to upper half (Ref. 86798).

Inhabits gravel and sand-bottomed flowing pools and runs of fast and usually clear creeks and small rivers (Ref. 86798).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00603 (0.00250 - 0.01453), b=3.05 (2.84 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (tmax=3).

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