Hyenas belong to the biological family Hyaenidae, which is often misunderstood due to the prominence of just one species in popular culture. The hyena family consists of four different species, each possessing a specialized coat, meaning there is no single answer to the question of hyena color. Their appearances are a result of millions of years of evolution, tailored to the specific habitats they occupy across Africa and parts of Asia. These diverse color patterns serve specific purposes related to camouflage, communication, and environmental adaptation.
The Coloration of Spotted Hyenas
The Spotted Hyena (Crocuta crocuta), the largest and most recognized species, features a coat color that is a pale grayish-brown or yellowish-gray base. Its relatively short, coarse fur is covered in an irregular pattern of dark, round spots across the back, flanks, and hindquarters. The size and distinction of these spots vary between individuals, though they are often darkest and most apparent in younger animals, fading as the hyena ages.
The lower legs and muzzle typically exhibit a darker coloration, often a dull brown or nearly black. Unlike its relatives, the Spotted Hyena possesses a less prominent mane, giving it a more rounded silhouette. The tail is relatively short and bushy, often ending in a dark, pom-pom-like tip. This overall coloration helps it blend into the dappled light and shadows of the African savanna environment.
Distinct Colors of Other Hyena Species
The three other members of the Hyaenidae family display different color patterns, primarily featuring stripes or a solid coat. The Striped Hyena (Hyaena hyaena) possesses a base coat ranging from a brownish-gray to a light yellow, overlaid with distinct black vertical stripes on the torso and legs. A long, erectile mane of coarse hair runs from the back of the head down to the base of the tail, which can be raised to make the animal appear larger during confrontation. This species also has a dark muzzle and almost black ears that stand out from the lighter base fur.
The Brown Hyena (Parahyaena brunnea) is distinguished by its long, shaggy coat, which is predominantly dark brown or black. This thick, dense fur is particularly long on the back and flanks. A pale, cream-colored fur ruff or mane encircles its neck, offering a stark contrast to the rest of its dark body. Its legs are marked with lighter horizontal stripes, which help break up the outline of the animal’s lower body.
The smallest member of the family, the Aardwolf (Proteles cristata), shares a striped appearance but on a much smaller frame. Its coat is yellowish or buff-yellow, marked with four to eight prominent dark brown or black vertical stripes across the body. Like the Striped Hyena, the Aardwolf has a pronounced dorsal mane that can be erected for display. Its black feet and tail tip complete the pattern, making its visual features distinct from its larger relatives.
How Coat Color Aids Survival
The specific shades and markings of each hyena species are tuned for their ecological niches, primarily for camouflage. The irregular dark spots of the Spotted Hyena are an effective form of concealment, helping them merge with the broken light and shadow found in the long grasses and acacia woodlands of the savanna. This spotted pattern functions as disruptive coloration, making it difficult for prey to discern the animal’s body shape while hunting and resting.
For the Striped Hyena and the Aardwolf, the vertical stripes serve a similar function in their scrub and grassland habitats. The stripes break up the contour of the body against the vertical lines of tall, dry grasses and shrubs, allowing them to remain inconspicuous when moving or lying down. The long, shaggy, dark coat of the Brown Hyena, which inhabits arid and semi-arid regions, provides a different advantage.
The dark, dense fur offers both insulation against temperature fluctuations, particularly the cold nights, and excellent camouflage against rocky terrain and dark bushveld. The ability of both the Striped Hyena and the Aardwolf to raise their dorsal manes is used not for camouflage, but as a visual threat display. This makes the animal appear larger and more intimidating to rivals or predators, a form of communication that relies on the coat’s physical structure.
