Short description आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय सौफट रेज़ (सम्पूर्ण): 10-12; ऐनल सौफट रेज़: 31 - 40; जानवरों की रीड़ का जोड़: 32 - 36. Can be diagnosed from other members of the genus Hyphessobrycon by the possession of a well-defined, oblique and marginal black stripe on each lobe of the caudal fin. Differs further from its congeners by the combination of the following characters: maxilla with 1-3 teeth, bearing 3-10 cusps; outer premaxillary row with 2-3 small teeth, bearing 5 or 7 cusps; iv-v, 27-36 anal-fin rays; 33-36 scales on the longitudinal series; two vertically elongated dark humeral spots; black caudal spot rounded or fan-shaped; dorsal and anal fins with the first rays dappled in black; and presence of minute bony hooks on the dorsal, anal and caudal fins of the mature males (Ref. 83966).

Found in a stream with clear water and rocky/sandy bottom, with irregularly distributed small stones, cobbles and boulders and with shallower sectors with fast-running water up to 60 cm deep, and deeper portions with around 2 m depth and abundant submerged vegetation (Ref. 83966).

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=0.01413 (0.00671 - 0.02974), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.3 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).

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