Final answer:
Nose protuberances can be found in various animals, including mammals, birds, and reptiles. Each group has their own unique respiratory system and structures associated with the nose protuberances.
Step-by-step explanation:
Nose protuberances are found in a variety of animals, but they are not exclusive to any specific group. In mammals, the nose protuberances include structures like the turbinates, which warm and moisten air as it is inhaled. Birds and reptiles, on the other hand, have a different respiratory system that involves air sacs and unidirectional airflow through the lungs.
