Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais (total) : 18 - 22; Espinhos anais: 0; Raios anais : 13 - 15. Diagnosis: Xenocharax crassus is distinguished from Xenocharax spilurus by the presence of a large black mark located anteriorly on the dorsal fin, vs. absence; a small, round, black spot at the posterior half of the caudal peduncle and covering a total of 4 to 6 scales, ±2 to 3 scales in horizontal and vertical direction alike, vs. a large ovoid spot covering a total of about 35 to 46 scales, ±8 to 10 scales in horizontal and vertical direction alike; and a wider mouth, 29-34% of head length vs. 24-29% (Ref. 114931). In addition, for the specimens of similar sizes, X. crassus has a shorter dorsal-adipose distance than X. spilurus; further, most X. crassus specimens have 6 supraneurals vs. 7 in X. spilurus (Ref. 52343, 114931).

Found almost exclusively in forested tributaries or in savannah streams under dense gallery forest (Ref. 114931).

Estimates based on models

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02188 (0.01053 - 0.04545), b=3.04 (2.85 - 3.23), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 3.0 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
