What are the long hairs of a rabbit's coat known as?

The long hairs of a rabbit's coat are known as guard hairs. These hairs serve several important functions, including protecting the rabbit from adverse weather conditions and predators. Guard hairs are typically coarser and longer than the undercoat, which consists of shorter, softer hairs that help insulate the rabbit. The guard hairs create a protective outer layer, reducing moisture penetration and providing some level of camouflage in the rabbit's natural environment. Understanding the role of guard hairs is essential for rabbit care and management, as they directly contribute to the animal's overall health and well-being.
