mane

The mane is the long hair that grows along the neck and sometimes the upper back of certain mammals. It is most noticeable in horses and lions, but also occurs in other species such as the maned wolf. The mane varies in length, density, and color and is distinct from the rest of the body coat and from the tail.

In horses, the mane runs from the withers toward the neck and consists of longer guard hairs over a shorter undercoat. Growth is influenced by hormones, breed, age, and season. Grooming practices include brushing, detangling, and, in many cases, braiding or trimming. Mane management can be part of breed standards and competitive presentation, and care is aimed at preventing skin irritation and matting.

In lions, the male’s mane is a dense fringe of longer hair around the head and neck that develops under the influence of testosterone during puberty. The size, color, and fullness of the mane vary by age, geographic population, and climate. The mane is thought to play a role in social signaling, may affect perceived threat, and can influence mating dynamics, while potentially offering some neck protection in fights.

Function and variation across species reflect different ecological and social roles. For some species, the mane provides visual signals of vigor or dominance; for others, it may contribute to protection or insulation. Environmental factors, genetics, and hormonal status help determine mane length and appearance, with seasonal changes occurring in some forms.

The term mane refers specifically to the long neck hair of certain mammals and is not a feature of humans. In species such as the maned wolf, a prominent neck plume is a characteristic trait that contributes to their identification.
