There are a couple of youtube.com videos of a possum walking along a wet paved area, with 15 furry baby possums hanging onto her back. Like other marsupials, possums give birth to very underdeveloped, hairless young, each the size of a peanut. After birth, they crawl into the mother's pouch for warmth and security. They nurse on milk from their mother, and remain attached to her until they are large enough to ambulate on their own. In the videos, it appeared the youngsters would soon have to let go. The mom wouldn't be able to bear their weight much longer.

There is a vulnerability about the possum carrying her entire family in daylight at the edge of a paved street near a man with a camera - her day and her priorities bumping into those of humans.
