Of all the questions researchers and wildlife rehabilitators encounter about pangolins, one of the most frequently asked is surprisingly simple: do pangolins drink water? The answer is nuanced, and it reveals a great deal about how these ancient, scale-covered mammals have adapted to some of Africa's most demanding environments.
Pangolins are specialist insectivores. In southern and eastern Africa, the ground pangolin (Smutsia temminckii) feeds almost exclusively on termites and ants, consuming tens of thousands of insects in a single foraging session. This diet is far more than a source of protein and fat — it is also the primary source of water.
Termites and ants are composed of roughly 65 to 75 percent water by body weight. When a pangolin devours thousands of these insects per night, it is simultaneously ingesting a substantial quantity of fluid. This form of dietary hydration, sometimes called preformed water intake, is common among specialist insectivores in arid regions, including aardvarks and certain bat species.
A ground pangolin foraging in the Limpopo bushveld may consume between 140 and 200 grams of insects on an active night. At roughly 70 percent water content, that translates to approximately 100 to 140 millilitres of fluid obtained through diet alone.
Field observations across Botswana, Zimbabwe and South Africa have produced only scattered records of pangolins drinking directly from water sources such as pans, rivers or water troughs. The behaviour appears to be opportunistic rather than routine. Some camera-trap footage from conservation areas in the Lowveld has captured ground pangolins pausing at seasonal pans, but such events are uncommon relative to the hours of foraging behaviour recorded.
This does not mean pangolins are physiologically incapable of drinking. When water is available and accessible, individuals may lap at it, particularly during very hot or dry conditions. The distinction is that they do not depend on open water to survive in the way that herbivores and many carnivores do.
Beyond dietary water, pangolins — like many desert-adapted mammals — generate a small amount of metabolic water as a by-product of digesting fats and carbohydrates. While this metabolic contribution is modest, it provides an additional buffer during periods when insect availability is lower.
Southern Africa's winter dry season, which runs from approximately May to September across Limpopo, Mpumalanga and North West Province, presents particular challenges for pangolin hydration. Rainfall drops sharply, ambient temperatures fluctuate dramatically between day and night, and termite foraging activity — which tends to increase after rain — declines in some areas.
Ground pangolins respond partly by reducing activity. They spend longer periods in burrows during cold, dry spells, lowering their metabolic demands and therefore their water requirements. Their low metabolic rate relative to body size, which is unusual even among mammals, makes this strategy viable.
Ground pangolins have one of the lowest metabolic rates recorded for any placental mammal of equivalent size. This physiological trait reduces water loss through respiration and allows the animals to tolerate periods of reduced food and fluid intake.
Some of the most water-stressed pangolin populations in southern Africa inhabit the margins of the Kalahari, a semi-arid savanna environment that receives under 400 millimetres of rainfall annually in its driest parts. Pangolins documented in these zones appear to function entirely on dietary hydration for extended periods, corroborating the view that open water access is supplementary rather than essential.
Research conducted through GPS telemetry projects in Botswana and South Africa has found no consistent correlation between pangolin home range positioning and proximity to permanent water sources. In contrast, home range selection does correlate strongly with termite mound density and soil type — reinforcing that food availability, and by extension dietary moisture, is the primary driver of habitat use.
While pangolins are well-adapted to low-water environments, the indirect effects of drought can still compromise their hydration balance. Prolonged drought reduces termite activity at the surface, forces colonies deeper underground, and can temporarily suppress ant population densities in affected areas. When insect availability drops, pangolins not only face caloric deficits but also reduced fluid intake.
Climate projections for southern Africa indicate that parts of the region will experience more intense and prolonged drought cycles through the middle of the twenty-first century. Conservation planners working with species such as the ground pangolin are beginning to factor dietary water dependency into climate vulnerability assessments, recognising that even a species that rarely drinks can be harmed by water scarcity through its food chain.
Understanding pangolin hydration is not merely an academic exercise — it has direct consequences for conservation practice. Pangolins are notoriously difficult to maintain in captivity, and dehydration is one of the documented causes of rapid decline in confiscated animals.
Rehabilitation centres in South Africa, including facilities affiliated with the African Pangolin Working Group, have developed protocols for assessing hydration status in newly admitted pangolins. Subcutaneous fluid administration is used in animals showing signs of dehydration, and live insect provision is prioritised over artificial diets wherever possible, precisely because of the dual nutritional and hydration value insects provide.
Carers typically offer shallow water dishes to pangolins in their enclosures. Some individuals lap water readily, while others show no interest. This variability may reflect individual differences, the degree of stress the animal is experiencing, or variation in the moisture content of the insects available. In any case, forcing water intake in a pangolin that shows no interest in drinking is not recommended and can cause further stress.
Signs of dehydration in a rescued pangolin include skin tenting, sunken eyes, lethargy beyond normal daytime torpor, and dry mucous membranes. Any pangolin displaying these signs requires immediate veterinary assessment.
Pangolins are not desert specialists in the strict sense, but they share many of the adaptive traits that allow true desert mammals to thrive in water-scarce environments. Their reliance on dietary hydration, low metabolic rate, and flexible activity patterns equip them well for the seasonal droughts common across southern and eastern Africa.
The direct answer to whether pangolins drink water is: occasionally, opportunistically, but not as a primary survival strategy. The insects they consume provide the bulk of their fluid needs, and their physiology is tuned to make the most of what is available. As rainfall patterns across Africa shift with a changing climate, understanding this relationship between pangolin diet and hydration will be essential for protecting populations that are already under severe pressure from poaching and habitat loss.
Pangolins rarely drink water directly from open sources. They obtain the majority of their moisture from the insects they consume, particularly termites and ants, which contain significant amounts of body fluid.
Pangolins are metabolically adapted to extract moisture from their insect diet. In southern Africa's arid zones, including parts of the Kalahari and the Limpopo lowveld, this dietary hydration strategy allows them to survive long periods without access to open water.
Extended drought can reduce termite and ant colony activity, indirectly reducing the moisture pangolins ingest. Severe drought conditions in southern Africa have been flagged as a secondary stress factor for wild pangolin populations.
Rehabilitators in South Africa do provide water to captive pangolins, and some individuals will lap water directly. However, replicating the hydration balance found in a natural insect diet remains one of the key challenges in pangolin captive care.
