Yes, wolves do have enhanced night vision compared to humans. This ability allows them to see in low-light conditions, making them effective hunters during dusk and dawn, which are prime times for their activity.
The reason for their superior night vision lies in the structure of their eyes. Wolves have a higher number of rod cells, which are responsible for detecting light and movement in dim conditions. Additionally, wolves have a reflective layer behind their retina called the tapetum lucidum. This layer reflects light that passes through the retina back into the eyes, giving them a second chance to detect that light. This is what gives their eyes the characteristic glow when illuminated at night.
Overall, this adaptation is crucial for their survival, as it enables them to track prey and navigate their environment after sunset more effectively than sights require higher light levels, such as humans.
