A prairie dog town may contain 15–26 family groups, [20] with subgroups within a town, called "wards", which are separated by a physical barrier. Family groups exist within these wards. Most prairie dog family groups are made up of one adult breeding male, two or three adult females, and one or two male offspring and one or two female offspring.
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia.They are natively found in Australasia, Wallacea, and the Americas.One of the defining features of marsupials is their unique reproductive strategy, where the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen.
These big-eyed, nocturnal marsupials are incredibly interesting animals to keep as pets, in no small part because, as their name implies, they glide through the air using thin gliding membranes ...

A female opossum may have one to three litters per year. [42] During the mating season, the male attracts the female by making clicking sounds with his mouth. [42] The female's estrus cycle is 28 days and lasts 36 hours. [42] Gestation lasts 11–13 days and the average litter size is 8–9 infants, although over 20 infants may be born. [42]
The latter subclass is divided into two infraclasses: pouched mammals (metatherians or marsupials), and placental mammals (eutherians, for which see List of placental mammals). Classification updated from Wilson and Reeder's "Mammal Species of the World: A Taxonomic and Geographic Reference" using the "Planet Mammifères" website. [1]
Australia is home to two of the five extant species of monotremes and the majority of the world's marsupials (the remainder are from Papua New Guinea, eastern Indonesia and the Americas). The taxonomy is somewhat fluid; this list generally follows Menkhorst and Knight [ 1 ] and Van Dyck and Strahan, [ 2 ] with some input from the global list ...
