Physical Features:
* Scrotum: Male possums have a prominent scrotum, which houses their testicles. This is the most obvious external difference.
* Size: Generally, males are larger than females, but this can vary depending on species and age.
* Body Shape: Males tend to have a more robust build, while females have a more slender form.
Reproductive Differences:
* Reproductive Organs: Females have a pouch, where their young develop. The pouch is more prominent during pregnancy and nursing.
* Estrous Cycle: Females have a distinct estrous cycle, which means they are fertile for a short period each month.
* Pregnancy: Female possums give birth to a litter of young, usually 4-6.
Behavioral Differences:
* Aggression: Male possums are generally more aggressive, particularly during mating season. This is due to competition for mates.
* Scent Marking: Both males and females mark their territories with scent, but males are more likely to engage in vigorous scent marking behavior.
Important Note: Distinguishing between male and female possums in the wild can be tricky, especially for inexperienced observers. The most reliable way to tell them apart is by checking for the presence of a scrotum.
Remember: Possums are wild animals. It's best to observe them from a safe distance and avoid any direct interaction.
