Opossums are interesting creatures. Being omnivores they will eat a wide variety of foods. Many are killed by automobiles each year when they cross roads, or search for road killed animals to eat.
They are marsupials having a pouch in which the young develop and nurse until they are weaned. They are widely known for their tendency to "play possum" or pretend to be dead when threatened. I did not approach this one closely enough for it to feel threatened, so instead of playing possum it just ambled off.
