The meerkat, a small, highly social mammal belonging to the mongoose family, is native to the arid plains of Southern Africa. Its primary habitat spans the Kalahari Desert and surrounding regions, where resources are often scarce and the climate is unforgiving. To thrive in this environment, the meerkat has developed a specialized omnivorous diet that is heavily reliant on the invertebrates found beneath the desert surface.
The Core Diet: Primary Food Sources
The meerkat diet is largely insectivorous, with invertebrates forming the bulk of their daily caloric intake. They consume a wide variety of arthropods, including beetles, moths, and their larvae, which are uncovered during foraging expeditions. Scientific analysis indicates that insects alone can constitute over 80% of the meerkat’s prey items, with soft-bodied grubs and hard-shelled beetles being common targets.
Beyond insects, their menu expands to include other ground-dwelling invertebrates such as spiders, centipedes, and millipedes. The meerkat is also a capable predator of small vertebrates, which provide supplementary protein and fat. These include small lizards, snakes, birds, and rodents, though these items are consumed less frequently than the primary invertebrate prey.
The diet is rounded out by occasional consumption of eggs and certain plant matter. Plant items like roots, tubers, and bulbs are sought out not necessarily for their nutritional value but for their high moisture content. This helps ensure the meerkats can sustain themselves across different seasons and fluctuating prey availability in the arid ecosystem.
Cooperative Hunting and Digging Techniques
Meerkats are active, diurnal foragers, spending a significant portion of their day systematically searching for food across their territory. They move as a cohesive group, or “mob,” a strategy that maximizes efficiency while minimizing individual risk. This cooperative movement prevents the over-depletion of food sources as they travel along different routes daily.
The primary method of acquiring food involves specialized digging, for which their long, non-retractable claws are perfectly adapted. Meerkats use a phenomenal sense of smell to locate concealed prey, such as beetle larvae and grubs, buried beneath the soil. Once the scent is picked up, they rapidly excavate the earth, using their pointed snout to probe the narrow trenches to grasp the prey.
While the group forages, one or more individuals take on the role of a sentinel, standing upright on an elevated vantage point like a mound or rock. The sentinel scans the sky and surrounding area for predators, such as birds of prey, providing an early warning system. Distinct alarm calls allow the rest of the mob to immediately dive into one of the numerous pre-dug escape tunnels, known as bolt holes, scattered throughout their range.
Dietary Adaptations to Arid Environments
The meerkat’s physiological and behavioral traits are tuned to surviving in a water-scarce desert environment. They rarely need to drink external water, acquiring nearly all necessary moisture directly from the food they consume, particularly insects, roots, and tubers. This ability to subsist on food-based moisture is a key adaptation to the low rainfall of the Kalahari.
A notable adaptation relates to the consumption of dangerous prey, such as scorpions and certain venomous snakes, to which meerkats possess a degree of immunity. Adults demonstrate a unique teaching behavior to train their young in safely disarming scorpions. This instruction is incremental, beginning with an adult presenting a dead scorpion to a pup.
As the pups mature, the adult progresses to giving them a live scorpion with the stinger removed, before finally presenting an unaltered, intact scorpion. This step-by-step introduction is one of the few documented examples of active teaching in the animal kingdom, ensuring pups learn the critical skill of disabling the prey before consuming it.
