侧线是鱼类用来创建其环境的水动力图像的主要方式。这些图像有助于各种行为，从趋流性到逃避反应。在这里，我们辨别的视觉和侧线模式在狩猎行为的幼虫，在不同的光条件下发展的贡献。特别是，洞穴动物有一个肥大的机械感觉，我们研究了常见的动物模式洞穴鱼Astyanax mexicanus和它最近的表面亲戚。我们在昼夜光照和完全黑暗的环境中饲养幼虫。然后，我们研究了神经乳突在侧线的分布，以及它们在光照和黑暗条件下的狩猎性能，有和没有侧线的贡献。我们报告说，所有的幼虫都依赖于侧线狩猎的成功，并在黑暗中提出的表面鱼有更大的依赖侧线。
The lateral line is the primary modality fish use to create a hydrodynamic image of their environment. These images contribute to a variety of behaviors, from rheotaxis to escape responses. Here we discern the contributions of visual and lateral line modalities in hunting behavior of larvae that have developed under different photic conditions. In particular, cave animals have a hypertrophied sense of mechanosensation, and we studied the common animal model cavefishAstyanax mexicanusand its closest related surface relative. We raised larvae in a diurnal light‐dark regimen and in complete darkness. We then examined the distribution of neuromasts in their lateral lines, and their hunting performance in light and dark conditions, with and without the contribution of the lateral line. We report that all larva depend on the lateral line for success in hunting and that surface fish raised in the dark have a greater dependency on the lateral line.
