Etymology
The term Didelphimorphia originates from Greek roots, where 'di' means 'two', 'delphys' means 'womb', and 'morphia' relates to 'form' or 'shape'. This terminology reflects the characteristic reproductive system of these marsupials, which involves two uteri. First described scientifically in the 19th century, Didelphimorphia distinguished itself through unique physical features and behaviors, setting it apart from other mammalian orders. The diversity of this group has allowed it to adapt to various habitats, from forests to urban environments, showcasing a successful evolutionary path that has fascinated biologists and ecologists alike.
