生物学特性     字汇 (例如 epibenthic)

The spines are said to be poisonous (Ref. 4537). Found in pools and slow flowing reaches of perennial and seasonal rivers; prefers riverine habitats to floodplains; shelters in holes or crevices or on the underside of logs, frequently in an upside-down position (Ref. 52193). Active at night, feeds on detritus and plant matter such as seeds as well as small invertebrates like insects and snails, and will scavenge readily (Ref. 52193). Breeds in summer during rainy periods (Ref. 7248, 52193). Oviparous (Ref. 205).

棘据说是有毒的。 (参考文献 4537) 出现于水池而且减慢不断而季节性河的流动范围。 喜欢到洪泛区的河中栖地。 在洞或裂隙的庇护所或在圆木的下面上, 时常采取颠倒的姿势。 活跃的在晚上, 吃碎屑与植物例如种子以及像昆虫与蜗牛的小型无脊椎动物。 意志轻易地清理。 卵生的.(参考文献 205) 繁殖于夏天。 (参考文献 7248)
