Here's why:
* Species Variation: Different possum species exist, and their vision may vary slightly.
* Individual Differences: Just like humans, some possums may have better vision than others due to factors like health and age.
* Limited Research: There's not a lot of scientific research specifically focusing on possum vision.
What we *do* know:
* Nocturnal: Possums are primarily nocturnal, meaning they are most active at night. This suggests their vision might be better adapted to low-light conditions than bright daylight.
* Eyeshine: Possums, like many nocturnal animals, have a reflective layer behind their eyes called the tapetum lucidum. This helps them gather more light, improving their ability to see in dim light.
Overall: While we don't have a precise distance, it's likely possums can see reasonably well, especially in low-light conditions. Their vision is likely adapted for navigating their environment at night.
