Краткое описание определительные ключи | морфология | морфометрия

членистые (мягкие) лучи анального плавника: 195 - 300.

Occurs in swamps, creeks, and river with lentic waters. Preys on small invertebrates, particularly the larvae of aquatic insects (Ref. 12225). Breeds before the start of the rainy season (Ref. 10645) or during the rainy season, with a fecundity count of 6473 eggs (Ref. 10643). Males persistently defend their territory and apparently make electric signals (by increased electric organ discharge (EOD) rates and interruptions thereof) to females passing by to draw in a spawning partner (Ref. 10605). Mature females' EODs are of higher frequencies than mature males (Ref. 10645). Plasma androgens modulate the EOD frequency during the breeding season (Ref. 10767). Embryos hatch on day 4; larvae begin to feed on day 11. The electric organ and electroreceptors are both present in the larva at the time of first exogenous feeding (Ref. 10605). Seems to reach sexual maturity at 1 year of age, based on breeding experiments (Ref. 10011).

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

Eggs of 3 mm diameter are deposited among plants. Larvae hatch after 4 days and start feeding after 11 days.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00193 - 0.00471), b=2.82 (2.69 - 2.95), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.40 se; based on food items.

Fishing Vulnerability (Ref. 59153): Very high vulnerability (84 of 100).

Категория цены (Ref. 80766): Unknown.
