An alternative or archaic term for a didelphid; a marsupial mammal, especially an opossum.
From Greek 'di-' (two) and 'delphos' (womb), referring to the two-chambered reproductive system of marsupials. Used scientifically in older zoological texts.
The Greek root 'delphos' (womb) shows how ancient anatomical observation shaped modern scientific naming—marsupials really do have a unique reproductive structure that warranted this special Greek-derived term!
