生物學特性     字彙 (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).

出現於海濱的小溪, 沙質底部之上覆蓋著枯葉了。 (參考文獻 27188) 偏愛被覆蓋著樹葉而且腐敗木材的一個泥底部,對於藏身處在白天期間的後者提供。 (參考文獻 35381) 吃魚與昆蟲 (參考文獻 27188), 底棲的浮游動物與甲殼動物。 (參考文獻 35381) 主要夜行.(參考文獻 11225) 持有有毒的刺狀鰭條。 它的性別比支持雌性是 2:1 。 雄魚的生殖器官為分泌與儲藏包括多葉狀的睪丸與附屬的器官。 受精是外部的。 非黏的沉性卵 (1.1 到 2.8 mm 直徑) 生產下來, 在大約 48 小時之後在 22個 ° C. 孵化 十天之後,仔魚大約重量 100個毫克,但是成長慢的 (0.5 到 1.15 一天 g) 。
