Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 8; членистые (мягкие) лучи анального плавника: 8. Gila pandora can be distinguished by the following characters: lateral line with 51-67 scales; dorsal fin with 8 rays; anal fin with 8 rays; 1st gill arch with 6-10 rakers; pharyngeal teeth 2,5-4,2; slightly subterminal mouth, extending to front of large eye; rounded, fairly blunt snout; fairly deep, compressed body; deep caudal peduncle; olive-gray above; 2 dusky stripes along silver sides (darkest on large individual), upper one extending to caudal fin, lower one to anal fin; and dusky to black caudal spot. Breeding individuals with red-orange (brightest in males) anal, dorsal and paired fin bases and side of head; orange lower side (Ref. 86798).
Inhabits flowing pools of headwaters, creeks and small rivers. Occurs usually near brush (Ref. 5723, 86798). Mid-water carnivore; feeds on zooplankton, aquatic and terrestrial insects, crustaceans, juvenile fish, and a limited amount of detritus (Ref. 79012).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00455 - 0.02896), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.3 ±0.2 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
