The muzzle of a rabbit refers specifically to the area surrounding the mouth, nose, and lower jaw. This region is crucial for various functions, including feeding, grooming, and social interactions. Understanding the anatomy of a rabbit's head is important for those involved in breeding, showing, or caring for rabbits, as it allows for better assessment of health and conformation to breed standards. This definition highlights the muzzle's role in the rabbit's overall structure and behavioral functions, distinguishing it clearly from other parts of the head or body, such as the ears or the back end.
