It’s prehensile, which means it can be used to hold or grasp things. You may have heard that opossums sleep while hanging by their tail, but that isn’t so — they’re too heavy to hang for very long. In fact, holding them that way is painful for them although babies may hang by their tails. Their feet are bare on the bottom. They have five hair- less, dexterous toes (some experts call them fingers). Each of the hind feet has a thumb, called a hallux. All their toes are clawed except for the thumbs, which are used to grasp branches when climbing. Virginia Opossums have no body odor because they lick Juvenile possums hanging by their tails themselves constantly. The licking, at least in part, has to do with thermoregulation of their body temperature — they lack sweat glands and the evaporating saliva helps to cool them. Virginia Opossums have a keen sense of touch. Their sense of smell is exceptional — they have 1,188 genes devoted to smell. (By comparison, humans have 396 olfactory genes devoted to smell, and dogs have 811.) Their eyesight is poor, however, and their senses of hearing and taste are rather weak, too. Virginia Opossums make only a few distinct vocalizations. They hiss, snarl, click and screech, and may make all of these sounds when showing aggression. Clicking is also made by males in mating behavior and by females when around their young. Young ones also make clicking sounds. Some sources say moth- ers make a purring sound to their young. Juvenile possums riding on their mother Opossums have a reputation for being dim-witted because they move slowly and have a small brain size (five times smaller than a raccoon’s). However, researchers found in a se- ries of tests that opossums are better than dogs, cats and other animals at remembering the location of food hidden in a maze; only humans were superior to them. (Continued on page 3) VOICE Page 3 VIRGINIA OPOSSUM Virginia Opossums are solitary, except when mating or caring for young. They’re strictly nocturnal, except in winter when they’re sometimes active in the daytime on warm days. Many people have seen them only as roadkill or in the spotlight of a suddenly-switched-on porch light. Coming face- to-face, opossums may freeze in place, but often they just turn and move away. For them, movement is usually a shuffling, clumsy-looking waddle, but if circumstances compel them, they can run at about 4 miles per hour — equivalent to a fast walk for a human. They know this isn’t fast enough to save them from most predators, so typi- cally they head for safety. They might crawl into a den, scale a tree (they’re expert at this) or swim (they’re able swimmers). Or they may drop “dead.” The Virginia opossum has many behaviors it uses to survive. When threatened, it will exhibit behaviors like running, growling, belching, urinating and even defecating. When frightened or harmed, opossums suddenly freeze, become stiff, drool and lie still as death; breathing will become slow and shallow. This coma-like state can last up to four hours Some predators will think the opossum is dead and go away! Virginia Opossum or Didelphis virginiana, Their genus name Didelphis is Ancient Greek for “double womb.” Their reproductive system is bifid, meaning there are two sets of reproductive organs. (The male’s penis is also bifid). Some of the fetuses develop in a left “Playing Possum” uterus and the others in a right uterus. They have a very short gesta- tion period — only 12 or 13 days. After their birth, the young continue their development in their mother’s pouch (marsupium). But first, they must perform a harrowing journey to get there. The newborns weigh 1/200th of an ounce — the size of a bee. Hairless and nearly transparent, they aren’t much more than embryos. Mothers prepare the way by licking a path through their hair for them to follow. With a swimming motion, the babies pull themselves blindly (literally, since their eyes are closed) along this path. The trek is only three or four inches, but for these little guys, it’s monumental. Treacherous, too. A sudden move by their mother and they’ll fall off and perish. The weaker babies will not make it, regardless. Those who make it to the fur-lined marsupium will find one of 13 teats aligned there in a horseshoe arrangement. This is their lifeline to Mother possum attending to her pouch further physical development, and they hang on tightly. If there are more than 13 babies, the extra ones will die. Two months later and the size of a mouse, babies have begun to outgrow their warm, protected environment that’s now stretched nearly to its limit. Ever so cautiously, they peek out. Then they duck back inside. They peek out. They duck back inside. They’ll do this many time over the next couple of weeks until finally they climb out — still clinging to their teat! They’ll stretch just as far as they possibly can but won’t turn loose. Eventually they let go and climb up onto their mother’s back where they ride for a few weeks learning the ropes. Then they drop off and stay with the mother for a short while before heading off on their own. Although well adapted to city life, their natural habitat is deciduous forests, but they also are found in farm- lands, prairies and wet areas, such as marshes and streams. Opossums live only a year or two in the wild and three or four years in captivity. Even though opossums eat everything, giving them the proper diet in captivity can be diffi- cult and many get painful metabolic bone disease. Opossums’ feet are soft and delicate with small claws, not designed for digging.
