Didelphi is a noun that refers to a group of marsupials belonging to the order Didelphimorphia. It encompasses a diverse array of animals primarily found in the Americas, particularly in Central and South America. The Didelphi order includes more than 100 species, commonly known as opossums or possums.
These creatures are characterized by their unique reproductive system, which sets them apart from other marsupials. The notable distinction of Didelphi is that they possess a bifurcated uterus, meaning that they have two separate uteri and typically give birth to a relatively large number of relatively undeveloped young, called joeys. Their reproductive method is referred to as polyprotodont, as these marsupials possess a substantial number of small, sharp teeth. This dental feature assists them in their omnivorous diet, which predominantly consists of insects, small vertebrates, fruits, and other plant matter.
The size and appearance of Didelphi species can vary significantly. Some may be as small as a rat, while others can grow to the size of a small dog. They are generally characterized by their long snouts, naked tails, and large, round ears. Their fur can be of various colors, such as brown, gray, or black, depending on the specific species.
Due to their adaptability and resilience, Didelphi species have managed to colonize a variety of habitats, including forests, grasslands, and even urban areas. With their unique reproductive and physiological features, Didelphi marsupials hold an important place in the diverse ecosystem of the Americas.
