生物学特性     字汇 (例如 epibenthic)

Appears to be smaller than P. cristata. P. geryi and P. cristata share the same biotope. Inhabits the high and middle parts of rivers, in zones with more or less fast flowing water and a rocky substrate (rock clusters consisting of pre-Cambrian pebbles, shales). Lies hidden under rocks, letting its barbel out to auscultate the exterior world. Emits growling sounds regularly (alarm signals?) and goes stalk-hunting frequently scouting around its hiding place. The population is organized in a hierarchical structure based on size, with markedly aggressive behavior. The juveniles are found mostly in seasonal little tributaries. Diet changes according to size: small crustaceans, insect larvae and adult, and fish. This slow-growing species can live for more than 10 years in the wild (Ref. 35381).

似乎比 P. cristata 更小. P. geryi P. cristata 分享相同的生存环境。 栖息于河的高而中央部份, 在有约略快速地的地方流动水与一个岩石的底部.(岩石聚集包含前寒武纪的小圆石,页岩) 躺卧在岩石下面藏,让它的触须向外到听诊外部的世界。 发出经常地怒吠声音 (警报信号?) 而且去悄悄靠近-时常猎食它的藏身处的周围斥候活动。 族群在以大小为依据的阶层结构被组织, 具有显着地侵略性行为。 稚鱼大部份在季节性的小支流中被发现。 食物改变根据大小: 小型甲壳动物,昆虫幼生与成鱼 , 与鱼。 这生长缓慢的种能在荒野中活到超过 10 年。 (参考文献 35381)
