Bactrian camel (Camelus bactrianus) is a large even-toed ungulate belonging to the family Camelidae. It is native to the arid and semi‑arid steppes, deserts, and mountainous regions of Central Asia, ranging from the Gobi Desert of Mongolia and northern China across the Taklamakan and into the Iranian plateau. Unlike its single‑humped relative, the dromedary (C. dromedarius), the Bactrian camel possesses two fatty humps that serve as energy reserves during periods of scarce forage. Its dense double coat—long outer hairs and a soft undercoat—provides insulation against extreme temperature fluctuations, from -40 °C winters to 45 °C summer highs. The species is well adapted to sparse vegetation, capable of drinking as little as 20 L of water per day and tolerating up to 30 % body‑weight loss without ill effect. Domesticated for millennia, Bactrian camels have been used as pack animals, sources of milk, meat, and fiber, and remain integral to the livelihoods of nomadic peoples such as the Kazakhs and Mongolians. While the domestic population numbers in the millions, the wild Bactrian camel (Camelus ferus) is critically endangered, highlighting the importance of conservation measures that protect the remaining feral and wild herds.

Socially, Bactrian camels form loose, matriarchal herds typically consisting of one dominant female, several subordinate females, and their offspring; adult males are often solitary or form temporary bachelor groups outside the breeding season. The herd moves slowly across the steppe, covering 10–30 km per day in search of grazing, and exhibits crepuscular activity, being most active at dawn and dusk to avoid midday heat. Territoriality is minimal; individuals maintain home ranges that may overlap extensively, especially around reliable water sources. Communication relies on a repertoire of vocalizations—low grunts, snorts, and a distinctive “hump‑click” sound—combined with visual signals such as ear positioning, tail flicking, and body posture. In stressful situations, camels may spit, a behavior that serves both as a deterrent and a means of expressing dominance. Bonding is reinforced through mutual grooming and the sharing of dung piles, which also serve as scent markers delineating group identity.

The Bactrian camel is a strict herbivore adapted to low‑quality, xerophytic vegetation. Its diet includes dwarf shrubs (e.g., Artemisia spp., Haloxylon ammodendron), grasses, succulent leaves, and occasional lichens or mosses in high‑altitude pastures. An adult camel can consume up to 15 % of its body weight in dry matter per day (≈ 30–45 kg), selecting plants based on moisture content and nutrient density. The species possesses a three‑chambered stomach and a highly efficient microbial fermentation system that extracts water and nutrients from fibrous material, allowing it to survive on plants with as little as 5 % moisture. During winter or drought, camels shift to browse on woody twigs and bark, and they can endure prolonged periods without drinking, subsisting on metabolic water produced during digestion. Feeding is typically conducted while standing, with the animal using its long, prehensile lips to grasp foliage and its split upper lip to strip leaves from stems.

Bactrian camels reach sexual maturity at 3–5 years for females and 4–6 years for males, though optimal breeding often occurs after 6 years of age. The breeding season is triggered by increasing daylight in early spring, when estrus cycles become synchronized among females. After a single mating, the gestation period lasts 12 months (≈ 350–380 days), one of the longest among terrestrial mammals. Typically a single calf is born; twins are rare (< 1 %). Newborns weigh 30–45 kg and can stand within an hour, though they rely on their mother’s milk for the first 6–8 months. The dam provides intensive care, protecting the calf from predators and harsh weather, while the herd offers additional vigilance. Calves are weaned at 8–12 months but may remain with the herd for several years before attaining full independence. Longevity of reproductive capacity can extend to 20 years in captivity, allowing a female to produce up to 20 offspring over her lifetime.

According to the IUCN Red List, the domestic Bactrian camel is listed as Least Concern, whereas the wild subspecies (Camelus ferus) is classified as Critically Endangered, with fewer than 1,000 individuals remaining in fragmented habitats across Mongolia and China. Primary threats to wild populations include habitat degradation from mining, overgrazing by livestock, and climate‑induced desertification, which reduce the availability of forage and water sources. Poaching for meat and hides, as well as competition with domestic camels for limited resources, further exacerbate declines. Conservation programs focus on establishing protected reserves, anti‑poaching patrols, and community‑based livestock management to mitigate human‑wildlife conflict. Captive breeding and re‑introduction efforts have produced modest successes, raising the wild population to an estimated 950 individuals as of 2023. Continued monitoring, habitat restoration, and transboundary cooperation are essential to prevent extinction.

• Bactrian camels can survive up to 30 days without water by metabolizing fat from their humps.
• Their double‑layered coat provides insulation that allows them to endure temperatures from -40 °C to 45 °C.
• They have a three‑chambered stomach that ferments tough desert plants, extracting up to 90 % of water from food.
• A single Bactrian camel can carry up to 300 kg of cargo over 40 km in a day.
• The wild Bactrian camel is one of the few large mammals that can drink salt water when freshwater is unavailable.
