биология     глоссарий (например epibenthic)

Occurs in littoral creeks, over sandy bottoms covered with dead leaves (Ref. 27188). Inhabits also lakes and rivers, but seems to prefer rivers with a very slight current (Ref. 6868). Prefers a muddy bottom covered with leaves and decaying wood, the latter providing for hiding places during the day (Ref. 35381). Feeds on fish and insects (Ref. 27188), benthic zooplankton and crustaceans (Ref. 35381). Omnivorous (Ref. 79585). Mainly nocturnal (Ref. 11225). Possesses poisonous spiny rays. Its sex ratio is 2:1 in favor of females. The male's reproductive apparatus includes multi-lobed testicles and accessory organs for secretion and storage. Fertilization is external. Non-sticking demersal eggs (1.1 to 2.8 mm diameter) are laid down, hatching after about 48 hours at 22°C. Ten days later, the larvae weigh approximately 100 mg but growth is slow (0.5 to 1.15 g per day).

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=0.00891 (0.00753 - 0.01055), b=3.02 (2.97 - 3.07), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.3 se; based on diet studies.
устойчивость к внешним воздействиям (Ref. 120179):  высокий, минимальное время удвоения популяции до 15 месяцев (Fec=41,334).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
