Here's what we know about their vision:
* Limited color vision: They are primarily dichromatic, meaning they can see blue and green but have difficulty distinguishing reds and oranges.
* Night vision: While they have larger pupils than humans, which allows for better light gathering, their retinas have fewer light-sensitive cells than humans. This means their night vision is still relatively poor compared to other nocturnal animals.
* Focus: Their eyes have limited ability to focus and may have difficulty seeing objects in the distance.
However, opossums make up for their poor eyesight with other senses:
* Excellent sense of smell: They rely heavily on their sense of smell to find food and navigate their surroundings.
* Sensitive hearing: Opossums have large, mobile ears that help them detect sound and identify threats.
* Tactile senses: They have sensitive whiskers and paws that help them explore and understand their environment.
In conclusion, while opossums have limited eyesight, they compensate for it with other highly developed senses that are crucial for their survival.
