Influence of chemical signals on the topographic orientation of the cave fish Caecobarbus geertsi Boulenger (Pisces, Cyprinidae).
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.
