Agonistic behaviour related to territorial defence is likely to be costly in terms of energy loss and risk of injury. Hence information about the fighting ability of a potential opponent could influence the outcome of the contest. We here study electric images of the territorial and aggressive weakly electric fish Gymnotus omarorum in the context of agonistic behaviour. We show that passive and active electric images may drive the approach towards an opponent. The likelihood of first attacks can be predicted in these fish based on electric image information, suggesting that aggressive interactions may in fact be triggered through the passive electrosensory information.
与领地防御相关的攻击行为在能量损失和受伤风险方面可能代价高昂。因此，关于潜在对手战斗能力的信息可能会影响竞争的结果。我们在此研究领地性和攻击性弱电鱼奥氏裸背电鳗在攻击行为背景下的电信号图像。我们发现，被动和主动电信号图像可能会促使其接近对手。基于电信号图像信息，可以预测这些鱼首次攻击的可能性，这表明攻击互动实际上可能是由被动电感觉信息引发的。
