Pantodon buchholzi, the African butterfly fish, inhabits an ecological niche just below the water surface. At that position, each eye necessarily views into the air through the surface of the water and into the water. Since Pantodon is an obligatory surface feeder, the ventral retina viewing the aerial environment provides all visual information for prey acquisition. The visual pathway of this fish reflects the divided visual field with structural differences in the retina and brain corresponding to the different views. In this study, we describe a specific type of neuron in the tectum that, due to its intrinsic structure, likely integrates visual and mechanoreceptor inputs. Because of its spatial distribution, this type of neuron is a candidate as a basic element in a network involved with prey acquisition.
非洲蝴蝶鱼（Pantodon buchholzi）栖息于水面以下的一个生态位。在那个位置，每只眼睛必然通过水面看向空气和水中。由于非洲蝴蝶鱼是一种 obligatory 水面捕食者，观察空中环境的腹侧视网膜为捕食提供了所有视觉信息。这种鱼的视觉通路反映了视野的划分，视网膜和大脑在结构上存在差异，对应于不同的视野。在本研究中，我们描述了顶盖中一种特定类型的神经元，由于其内在结构，它可能整合视觉和机械感受器输入。由于其空间分布，这种类型的神经元是参与捕食的网络中作为基本元素的候选者。
“obligatory”这里可能是“专性的”之类意思，原文表述稍有点模糊，不太确定确切准确的中文释义，但不影响整体句子理解。
