Massachusetts Wildlife Rehabilitator Practice Exam

Which animal is noted for not being as susceptible to rabies?

1. Striped Skunk

2. Virginia opossum

3. Little Brown Bat

4. Gray fox

The correct answer is: Virginia opossum

The Virginia opossum is notable for its lower susceptibility to rabies compared to other mammals. This is primarily due to its unique physiological characteristics, such as a lower body temperature that hinders the rabies virus's ability to thrive and multiply. Additionally, opossums are less likely to come into contact with rabid animals because of their behavior; they tend to avoid confrontation and can play dead when threatened, reducing their chance of exposure. In contrast, species like the striped skunk, little brown bat, and gray fox are more prone to rabies infection, as they are often more aggressive or territorial, leading to increased encounters with rabid animals. These factors contribute to a higher incidence of rabies in these species compared to the opossum.
