Some common synonyms include "beak" for birds, "muzzle" for dogs and horses, and "snout" for pigs and anteaters. "Jaws" and "mouthparts" are more general terms that can be used for a variety of animals, while "mandible" specifically refers to the lower jaw of a mammal. "Proboscis" is a long, tubular mouthpart found in insects, while "chelicerae" are pincer-like mouthparts found in spiders and scorpions.
