Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

Gymnotus chaviro is unique among members of the G. carapo group (sensu Albert et al., 2004) in having a color pattern composed of oblique, dark, unbroken pigment bands along the length of the body, dark band-pairs with wavy, irregular margins, mainly unbranched or incompletely separated, pale inter-bands rarely reaching to the dorsal midline on the anterior half of the body and crescent-shaped in abdominal area (Ref. 83382).

Facultative air-breathing in the genus (Ref. 126274)

Estimates based on models

Phylogenetic diversity index (संदर्भ 82804): PD₅₀ = 0.5000 [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 (संदर्भ 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

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