Abstract

Adult individuals of the cave cyprinid Caecobarbus geertsi Boulenger, when placed in a choice-apparatus, show a significant tendency to orient towards the zone in which water from a tank occupied by known conspecifics is introduced. The phenomenon is briefly discussed in relation to physical features of the subterranean biotopes.

摘要

洞穴鲤科鱼类杰氏盲鲤的成年个体被放置在一个选择装置中时，会表现出明显的倾向，即朝着引入来自已知同种个体所在水箱的水的区域游动。结合地下生物群落的物理特征，对这一现象进行了简要讨论。
