While never on screen, in various other media, the xenomorph has been given two different binomial Latin specific names:Internecivus raptus and Linguafoeda acheronsis. Either translate:
Internecivus raptus into English (I'll be liberal on this),
OR
identify the organ of the creature's body being referenced in the name Linguafoeda acheronsis.
"murderous thief" or "tongue" ("foul tongue of Acheron") ... we'll be lenient on equivalent translation
