биология     глоссарий (например epibenthic)

Obligate air-breathing (Ref. 126274); Adults occur in sluggish or standing water in canals, lakes, and swamps (Ref. 12693). Inhabit waters with submerged aquatic vegetation (Ref. 12693). Usually found only in deep pools in rivers and occasionally in lakes. They enter flooded forest (Ref. 9497). Carnivorous and subsist on fish, frogs, snakes, insects, earthworms and tadpoles (Ref. 1479). There are reports of this species taking water birds, snakes, and rodents. Males are territorial. May bite when caught (Elliot Bligh, pers. comm., 2001).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

Builds floating nest of weeds and leaves where the orange-yellow eggs are deposited. Eggs hatch in 36 to 48 hours and fry remain in the nest for about 10 days after hatching. Parents guards the fry for about a month.

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=0.00776 (0.00454 - 0.01328), b=2.98 (2.83 - 3.13), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.80 se; based on food items.
Generation time: 4.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
устойчивость к внешним воздействиям (Ref. 120179):  средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (K=0.23).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (55 of 100).
Категория цены (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 34 [15, 87] mg/100g; Iron = 0.767 [0.514, 1.242] mg/100g; Protein = 18.3 [17.3, 19.4] %; Omega3 = 0.198 [0.080, 0.492] g/100g; Selenium = 54.1 [21.9, 128.7] μg/100g; VitaminA = 55.8 [20.4, 150.1] μg/100g; Zinc = 0.697 [0.481, 1.074] mg/100g (wet weight); based on nutrient studies.
