Indian Spotted Chevrotain

The Indian spotted chevrotain (Moschiola indica) is a small, nocturnal ruminant belonging to the family Tragulidae, the most primitive group of even-toed ungulates. Endemic to the Indian subcontinent, its range extends across the Western Ghats, central Indian forests, the Himalaya foothills, and into Sri Lanka and parts of Bangladesh and Nepal. It inhabits dense tropical evergreen and semi‑evergreen forests, moist deciduous woodlands, and shrub‑dominated undergrowth where thick leaf litter provides cover. Adults weigh only 2–4 kg and measure 45–55 cm in head‑body length, with a distinctive spotted coat of white or cream spots on a reddish‑brown background, and short, straight horns (tusks) in males. The species is solitary or found in pairs, relying on its cryptic coloration and keen hearing to avoid predators such as leopards, dholes, and large birds of prey. Reproductive output is low, with a single fawn born after a gestation of about 150 days. The Indian spotted chevrotain is classified as Least Concern by the IUCN, but habitat fragmentation and hunting pressure have caused local declines. Ongoing conservation efforts focus on preserving forest corridors and enforcing anti‑poaching regulations to maintain viable populations across its fragmented range.

Indian spotted chevrotains are primarily solitary, with adult males maintaining exclusive home ranges that may overlap those of several females. Activity peaks during the crepuscular and nocturnal periods; individuals retreat to dense understory during daylight, emerging at dusk to forage. Territories are marked by scent glands on the throat and preorbital region, and occasional vocalizations—soft whistles or snorts—communicate alarm or reproductive readiness. Home range sizes vary with habitat quality, ranging from 0.5 ha in rich evergreen forest to over 2 ha in degraded scrub. Social interactions are limited to brief courtship bouts and occasional mother‑offspring contact; otherwise, individuals rely on camouflage and acute hearing to detect predators. Seasonal movements are modest, with chevrotains shifting locally in response to fruiting cycles and water availability, but they do not undertake long‑distance migrations.

The Indian spotted chevrotain is a strict herbivore, browsing on a diverse array of forest floor vegetation. Its diet consists primarily of fresh leaves, shoots, and buds of understory shrubs such as Lantana, Clerodendrum, and various Rubiaceae species. Fruit consumption is opportunistic; seasonal berries of Ficus, Myrtus, and Solanum provide essential carbohydrates and vitamins. In the dry season, the chevrotain supplements its intake with bark, twigs, and fallen fruits, while occasional ingestion of fungi and lichens has been recorded. Feeding occurs in short bouts lasting a few minutes, interspersed with periods of vigilance. Chevrotains possess a simple stomach and a functional rumen, allowing rapid fermentation of fibrous material; they typically consume 0.5–1 kg of foliage per day, equivalent to roughly 15–20 % of their body weight.

Females reach sexual maturity at 12–14 months, while males mature slightly later at 15–18 months. Breeding occurs year‑round but peaks during the rainy season (June–September) when food resources are abundant. After a gestation period of approximately 150 days, a single fawn—occasionally twins—is born concealed in a shallow depression of leaf litter. Newborns are precocial, opening their eyes within 24 hours and following the mother shortly after birth. Lactation lasts about 45 days, after which the juvenile becomes independent but may remain within the mother’s range for several months. Longevity in the wild averages 8–10 years, extending to 12–15 years in captivity, reflecting low reproductive rates and high juvenile mortality due to predation.

The IUCN classifies the Indian spotted chevrotain as Least Concern, yet its populations are fragmented and declining in many parts of its range. Primary threats include habitat loss from agricultural expansion, logging, and infrastructure development, which reduce the dense understory essential for concealment. Hunting for meat and traditional medicine, though not widespread, adds localized pressure, especially in regions where enforcement is weak. Road mortality and predation by increasing numbers of feral dogs also impact survival. Population surveys suggest a decline of 10–20 % over the past three decades, with estimated numbers ranging from 150,000 to 250,000 mature individuals. Conservation actions focus on protecting remaining forest blocks, establishing wildlife corridors, and community‑based anti‑poaching initiatives. Monitoring programs using camera traps and line‑transect surveys are essential to assess trends and guide management.

• The Indian spotted chevrotain is the smallest hoofed mammal in the world, weighing less than a domestic cat.
• It lacks true antlers; males have short, straight, upward‑curving canine tusks used in male‑male combat.
• Despite its size, it can run up to 30 km/h in short bursts to escape predators.
• Chevrotains have a unique double‑stomach system that allows rapid digestion of high‑fiber diets.
• Their spotted coat provides excellent camouflage, and they can remain motionless for several minutes to avoid detection.
