Summary Adult individuals of the cave cyprinidCaecobarbus 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 the physical features of the subterranean biotopes.Research supported by the Centro di Studio per la Faunistica ed Ecologia Tropicali del Consiglio Nazionale delle Ricerche. |
