Giant anteaters have no teeth, but their elongated heads hide a 60-centimetre tongue covered in sticky saliva.

Digestion is breaking food into smaller bits, either mechanically — like by chewing — or chemically, like with the enzymes in my saliva and stomach.

Back in the 80s, one researcher proposed that even if their prey initially escapes, Komodo dragon saliva might store harmful bacteria, which could proliferate in the bite wound and help kill the animal.
