What characteristic defines a rabbit with bell ears?

A rabbit with bell ears is characterized by heavy tips that fall or droop downwards. This specific ear structure gives the rabbit a unique appearance, distinct from other ear types like erect or semi-erect ears. The heaviness and flexibility of the ear tips cause them to bend downward, resembling bells, which is how they get their name.

Understanding this characteristic is crucial for proper identification and classification within rabbit breeds. The other ear types, such as erect ears, do not share this drooping feature and contribute to different breed standards. Erect ears stand upright, while rounded ends do not accurately describe bell ears, as the latter specifically highlight the drooping quality due to their weight.
