Ears

Within the order of lagomorphs, the ears are used to detect and avoid predators. In the family Leporidae, the ears are typically longer than they are wide. For example, in black-tailed jackrabbits, their long ears cover a greater surface area relative to their body size, which allows them to detect predators from far away. In contrast with cottontail rabbits, their ears are smaller and shorter, requiring that predators be closer before they can detect them and flee.

Evolution has favored rabbits with shorter ears, so the larger surface area does not cause them to lose heat in more temperate regions. The opposite can be seen in rabbits that live in hotter climates; possessing longer ears with a larger surface area helps with dispersion of heat. Since sound travels less well in arid as opposed to cooler air, longer ears may aid the organism in detecting predators sooner rather than later in warmer temperatures. Rabbits are characterized by shorter ears than hares. Rabbits' ears are an important structure to aid thermoregulation as well as in detecting predators due to the way the outer, middle, and inner ear muscles coordinate with one another. The ear muscles also aid in maintaining balance and movement when fleeing predators.
