鲸足类具有视觉和机械感受系统，可以用来感知和回应接近的捕食者。虽然视觉大概起着主导作用，侧线模拟捕食者逃避的重要性还没有在头足类动物中研究。为了测试各自的角色的视觉和侧线模拟，简短的鱿鱼，Lolliguncula brevis，观察在夏季比目鱼，Paralichthys dentatus的存在下，在光照和黑暗条件下，其侧线模拟完整和消融。毛细胞消融是通过首次在头足类动物上使用的药理学技术实现的。与黑暗消融组相比，在光非消融和光消融组中存活的捕食者-猎物相互作用的比例显着较高。各治疗组间存活的相互作用平均数量各不相同，光未消融组的成功率显著高于光消融组、暗未消融组和暗消融组。这些发现表明，虽然视觉是主要的感觉，侧线模拟也有助于捕食者逃避鱿鱼。
Cephalopods have visual and mechanoreception systems that may be employed to sense and respond to an approaching predator. While vision presumably plays the dominant role, the importance of the lateral line analogue for predator evasion has not been examined in cephalopods. To test the respective roles of vision and the lateral line analogue, brief squid, Lolliguncula brevis, were observed in the presence of summer flounder, Paralichthys dentatus, under light and dark conditions with their lateral line analogue intact and ablated. Hair cell ablation was achieved through a pharmacological technique used for the first time on a cephalopod. The proportion of predator–prey interactions survived was significantly higher in the light non-ablated and light ablated groups compared with the dark ablated group. The mean number of interactions survived varied across treatment groups with the light non-ablated group having significantly more success than the light ablated, dark non-ablated and dark ablated groups. These findings demonstrate that although vision is the primary sense, the lateral line analogue also contributes to predator evasion in squid.
