| 摘要 | Eye size plays a crucial role in determining visual acuity, sensitivity, and temporal resolution, reflecting adaptations of vertebrates to their environment. By examining 1,176 specimens of 33 snake species in Taiwan, we explored the relationship between relative eye size and ecological (i.e., habitat), behavioral (i.e., diel activity pattern, foraging strategy), and physiological traits (i.e., the presence of pits) in six snake families. We found that terrestrial and/or diurnal snakes tend to have a larger relative eye size, indicating the evolutionary response to changes in habitat type and activity patterns. However, we found no evidence of effect of foraging strategies or the presence of pits on eye size, suggesting that snakes may have similar visual demands regardless of how they hunt or the existence of infrared system. Our findings shed light on the adaptive significance of visual performance in snakes, as well as the interplay between behavior, ecology, physiology, and phylogeny in the evolution of optimal vision. |
