Walrus-human hybrid

Walrus-human hybrids were, as the name suggested, a part-walrus, part-human species. Little was known about them, other than that they evolved long after humanity had become competent space travellers. The Eighth Doctor, Trix and Fitz once met one of the species by the name of Nambit, son of Quaff. (EDA: The Tomorrow Windows)

Behind the scenes
Quaff provides readers with a name for Nambit's species that is otherwise absent in The Tomorrow Windows. He refers to himself as "the freakish walrus-human hybrid I am today".
