Rock hyrax

An unlikely relative of the elephant

At first glance the rock hyrax resembles an oversized guinea pig or a tailless marmot. Its true affinities, however, are startling: its closest living relatives are not rodents but elephants and the sirenians (manatees and dugongs). Anatomical clues, such as tusk-like upper incisors and features of the skeleton, betray this ancient shared ancestry.

The body is compact, roughly 30–50 cm long, with no visible tail and a coat of brownish-grey fur. A conspicuous dorsal patch surrounds a scent gland used in communication. The soles of the feet are bare and kept moist, with rubbery pads that act like suction cups, letting the animal scramble confidently up smooth, steep rock faces.

Habitat and distribution

It is among the most widespread of the hyraxes, ranging across much of sub-Saharan Africa, along the north-eastern edge of the continent and into the Near East, from the Arabian Peninsula to the Levant. It favours rocky outcrops, boulder fields and cliffs, whose crevices offer shelter from predators and weather. It lives from sea level up to high mountain elevations.

Social life and warmth

Rock hyraxes live in colonies that may number several dozen individuals, centred on a dominant male with a group of females and their young. Because they thermoregulate poorly, they spend long morning hours basking in the sun, often huddled together. Sentinels watch for danger and give sharp alarm calls that alert the whole colony. Their vocal repertoire is unusually complex, with almost "dialect-like" differences between populations.

Diet and curiosities

The rock hyrax is a herbivore, feeding on grasses, leaves, shoots and fruit, and copes with tough, fibrous plants thanks to a compartmentalised stomach and lengthy gut fermentation. Colonies use fixed latrine sites; the crystallised deposits of urine and droppings, known as hyraceum, have been studied as a climate archive and were once used in perfumery. For all its placid looks, the hyrax is quick and agile among the rocks.

Conservation

The IUCN lists the species as Least Concern: its range is vast and populations are stable. It is locally hunted for meat or treated as a garden pest, but overall it faces no significant threat.
