生物学特性     字汇 (例如 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).

出现于海滨的小溪, 沙质底部之上覆盖着枯叶了。 (参考文献 27188) 偏爱被覆盖着树叶而且腐败木材的一个泥底部,对于藏身处在白天期间的后者提供。 (参考文献 35381) 吃鱼与昆虫 (参考文献 27188), 底栖的浮游动物与甲壳动物。 (参考文献 35381) 主要夜行.(参考文献 11225) 持有有毒的刺状鳍条。 它的性别比支持雌性是 2:1 。 雄鱼的生殖器官为分泌与储藏包括多叶状的睾丸与附属的器官。 受精是外部的。 非黏的沉性卵 (1.1 到 2.8 mm 直径) 生产下来, 在大约 48 小时之后在 22个 ° C. 孵化 十天之后,仔鱼大约重量 100个毫克,但是成长慢的 (0.5 到 1.15 一天 g) 。

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).
营养阶层 (Ref. 69278):  3.9   ±0.3 se; based on diet studies.
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Fec=41,334).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
