Key Differences
Marsupials are a unique group of mammals that primarily carry and nurture their young in external pouches. In contrast, Rodents are mammals characterized by a pair of continuously growing incisors in both the upper and lower jaws.
While many Marsupials are native to Australia, such as kangaroos, wallabies, and koalas, Rodents are found globally and represent the largest group of mammals in terms of species number.
Marsupials give birth to relatively undeveloped young, which continue to develop outside the womb, typically inside the mother's pouch. Rodents typically give birth to more developed young, without the need for a pouch.
Marsupials can range from small insectivorous species like the marsupial mole to larger herbivores like the kangaroo. Rodents, on the other hand, are typically smaller and are known for their gnawing habits, driven by their ever-growing teeth.
Taxonomically, Marsupials are part of the infraclass Marsupialia. Rodents, however, belong to the order Rodentia, which includes creatures like mice, rats, squirrels, and beavers.
