韦伯定律适用于0.96-5.57°圆盘的斑海豹的视觉辨别。我们得到了一个值为0026韦伯的分数，这与0.029报告的人类作出的视觉线长度歧视的值密切相关。强度辨别对这些盘辨别阈值有贡献的可能性是低的。
Weber's Law applies to visual discrimination by spotted seals of discs of 0.96–5.57°. We obtained a value for Weber's fraction of 0026, which compares closely with the value of 0.029 reported for humans making visual line length discriminations. The likelihood of intensity discriminations contributing to these disc discrimination thresholds is low.
