deskripsi pendek Morfologi | Morfometrik

duri punggung lunak (Keseluruhan (total)): 10-11; vertebrata, bertulang belakang: 32 - 34. Priocharax nanus can be distinguished from its congeners (P. ariel and P. pygmaeus) by having i,6 pelvic-fin rays (vs. i,5), a claustrum (vs. claustrum absent) and two postcleithra (vs. postcleithra absent). It can be further diagnosed from P. ariel by having 9-10 gill rakers on the lower limb of the first branchial arch (vs. 11-13), caudal peduncle length 13.5-16.8 % SL (vs. 18.1- 23.7 % SL); and 21-26 branched anal-fin rays (vs. 16-21) (Ref. 96862).

Collected in the black acidic waters of the Rio Negro basin around the submerged vegetation at depths of about 1 m or less and from an area exposed to the sun in warm, shallow water, approximately 50 cm deep (Ref. 96862).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.5 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).

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