攻击性模仿者是掠夺性物种，类似于“模型”物种，以牺牲信号接收器来获得食物，交配机会或运输。模型的成本可能是可变的，这取决于模仿者和信号接收者之间的相互作用的强度。在印度太平洋，蓝条纹fangblenny Plagiotremus cornerhynchos模仿少年清洁濑鱼Labroides dimidiatus。而不是从较大的珊瑚礁鱼去除体外寄生虫，fangblennies攻击鱼类以捕食鳞片和身体组织。在这项研究中，青少年清洁濑鱼遭受显着的成本时，与P。此外，该模型所产生的成本随着模仿者对信号接收器的攻击性的增加而增加。这显然是因为在信号接收器的行为变化，作为清洁站与模仿，攻击频繁访问less.Variation的模型所产生的成本可能会影响模仿的准确性和避免学习的信号接收器，从而影响整体的成功和维护的模仿系统。
Aggressive mimics are predatory species that resemble a 'model' species to gain access to food, mating opportunities or transportation at the expense of a signal receiver. Costs to the model may be variable, depending on the strength of the interaction between mimics and signal receivers. In the Indopacific, the bluestriped fangblenny Plagiotremus rhinorhynchos mimics juvenile cleaner wrasse Labroides dimidiatus. Instead of removing ectoparasites from larger coral reef fish, fangblennies attack fish to feed on scales and body tissue. In this study, juvenile cleaner wrasse suffered significant costs when associated with P. rhinorhynchos mimics in terms of reduced cleaning activity. Furthermore, the costs incurred by the model increased with heightened aggression by mimics towards signal receivers. This was apparently because of behavioural changes in signal receivers, as cleaning stations with mimics that attacked frequently were visited less. Variation in the costs incurred by the model may influence mimicry accuracy and avoidance learning by the signal receiver and thus affect the overall success and maintenance of the mimicry system.
