opossum lifespan

[30] They give birth to litters of up to 20 young. These areas may be below ground or above. [29] The young are therefore born at a very early stage, although the gestation period is similar to that of many other small marsupials, at only 12 to 14 days. [43] Similar adaptations are seen in other small predatory mammals such as mongooses and hedgehogs. It was believed that the shape of the penis was a perfect fit for the female opossum’s nose.

If caught and then handled, possums will frequently defecate and the glands by the base of their tail will release a secretion that is pea-green. Though they will temporarily occupy abandoned burrows, they do not dig or put much effort into building their own. Like that of all marsupials, the fur consists of awn hair only, and the females have a pouch. Their tails are eaten as a folk remedy to improve fertility.

Why this fascinating process occurs and why it occurs only in the American marsupials and not the Australian marsupials is not completely understood The pairing of spermatozoa may increase sperm motility in the female reproductive tract and/or may help protect the sperm acrosomes during passage n the female tract. Possums are not typically aggressive, but they do have a defensive posture when threatened. Life Cycle Although a litter of opossums may have up to 20 babies, less than half of these animals will survive on average. Marsupials give birth to fetal-like young following a brief gestation period. If cornered, they will either sit back or crouch down and open their mouth. Opossums eat dead animals, insects, rodents and birds. [32] Female opossums often give birth to very large numbers of young, most of which fail to attach to a teat, although as many as thirteen young can attach,[33] and therefore survive, depending on species. Krause, William J.; Krause, Winifred A. The Virginia opossum lives in regions as far north as Canada and as far south as Central America, while other types of opossums only inhabit countries south of the United States. Many other do not have a pouch at all. [4] Like most marsupials, the male opossum has a forked penis bearing twin glandes. Some species of opossums have prehensile tails, although dangling by the tail is more common among juveniles. The incisors are very small, the canines large, and the molars are tricuspid. Opossum Feces – Appearance And Health Risks [57][58] In 1909, a "Possum and 'Taters" banquet was held in Atlanta to honor President-elect William Howard Taft. The species that many people think of when hearing about this animal is the common opossum, also known as Virginia opossum. Some families will group together in ready-made burrows or even under houses.

When an opossum is "playing possum", the animal's lips are drawn back, the teeth are bared, saliva foams around the mouth, the eyes close or half-close, and a foul-smelling fluid is secreted from the anal glands. The young are weaned at approximately 3 months of age and are on their own at 4 1/2 – 5 months when they are approximately 7-9 inches long from nose to rump, excluding the tail. Opossums have sharp claws that help them dig into the bark of trees while climbing. Whether you have an interest in learning more about the wildlife around your home or want to better understand them as a way to keep them off your property, finding out more about opossums can be a very interesting endeavor. In the case of baby opossums, however, the brain does not always react this way at the appropriate moment, and therefore they often fail to "play dead" when threatened. During the breeding season (January to July in the United States), males and females find each other and mate. Opossums don’t build shelters themselves so you can find them in old buildings or sheds as well or in fallen logs, hollow trees, and cavities in brush piles or rocks. [21][22][23] Most opossums are scansorial, well-adapted to life in the trees or on the ground, but members of the Caluromyinae and Glironiinae are primarily arboreal, whereas species of Metachirus, Monodelphis, and to a lesser degree Didelphis show adaptations for life on the ground. Being solitary animals, opossums avoid each other. As they become too large to fit in the pouch, they climb onto the mother’s back and are carried as she searches for food. Not all of the newborn opossums will make it this far.
