ABSTRACT Stomatopod crustaceans have highly mobile, independently moving compound eyes that are sensitive to both linearly and circularly polarized light. They rotate their eyes to predictable angles when viewing a linearly polarized target, and they scan their eyes frequently to sample the visual field. Angles of scans are roughly perpendicular to the plane of the midband (a set of specialized parallel rows of equatorial ommatidia). We investigated scanning eye movements in one Caribbean stomatopod species (Neogonodactylus oerstedii) in uniform visual fields that were vertically polarized, horizontally polarized, or depolarized. We found that mean eye rotation and scan angles differed significantly among these different treatments. Average scan angles differed by 12°, being more horizontal in a vertically polarized field than in a horizontally polarized one, and also more horizontal in a vertically polarized field than in a depolarized field. Thus, these stomatopods adjusted visual scanning to the polarization of the visual environment.

在偏振光场中扫描口足类甲壳类动物 Neogonodactylus oerstedii 的眼球运动

摘要 口足类甲壳类动物具有高度移动、独立移动的复眼，对线偏振光和圆偏振光都很敏感。在观察线性偏振目标时，他们将眼睛旋转到可预测的角度，并经常扫描眼睛以对视野进行采样。扫描角度大致垂直于中带平面（一组专门平行的赤道小眼）。我们在垂直极化、水平极化或去极化的均匀视野中研究了一种加勒比口足类动物 (Neogonodactylus oerstedii) 的扫描眼球运动。我们发现在这些不同的治疗中，平均眼睛旋转和扫描角度有显着差异。平均扫描角度相差 12°，垂直极化场比水平极化场更水平，垂直极化场比去极化场更水平。因此，这些口足类动物根据视觉环境的极化调整视觉扫描。
