蝌蚪表现出对不同环境的偏好，但控制这些选择的感觉模式尚未得到很好的理解。在这里，我们研究了白化和野生型非洲爪蟾蝌蚪的光偏好和相关的感觉机制。我们发现，与野生型蝌蚪相比，白化蝌蚪在黑暗环境中待的时间更长，尽管它们在总体活动上没有差异。当蝌蚪的视神经被切断或松果体被移除时，这种偏好仍然存在，这表明这些感觉系统本身并不是趋光性所必需的。这些实验是由一门本科实验课进行的，强调了在课堂环境中对X. laevis蝌蚪行为的分析如何揭示对动物行为的新见解。
Tadpoles display preferences for different environments but the sensory modalities that govern these choices are not well understood. Here, we examined light preferences and associated sensory mechanisms of albino and wild-type Xenopus laevis tadpoles. We found that albino tadpoles spent more time in darker environments compared to the wild type, although they showed no differences in overall activity. This preference persisted when the tadpoles had their optic nerve severed or pineal glands removed, suggesting these sensory systems alone are not necessary for phototaxis. These experiments were conducted by an undergraduate laboratory course, highlighting how X. laevis tadpole behavior assays in a classroom setting can reveal new insights into animal behavior.
