Meerkat Biology and Behavior
Meerkats are fascinating creatures—their unique physical features and complex social behaviors make them standout members of the mongoose family.
Physical Characteristics
Meerkats, or Suricata suricatta, are small, burrowing mammals with a standout appearance.
They have slender bodies that average a body length of 25 to 35 centimeters and a weight of around 720 grams.
Their tails add another 17 to 25 centimeters in length, helping them balance when they stand upright.
Their pointed snouts, black-tipped ears, and sharp claws for digging make them well-adapted for a life in arid environments.
One of the most distinctive physical features can be found around their eyes; the dark patches act to reduce glare and enhance vision under the bright desert sun.
- Body Length: 25-35 cm
- Weight: Approx. 720 g
- Tail Length: 17-25 cm
- Notable Features: Pointed snouts, black-tipped ears, sharp claws, dark eye patches
Reproductive Habits
In terms of reproduction, meerkats are fascinatingly cooperative.
Females are the dominant breeders in their groups, often referred to as ‘mobs’.
Litters usually consist of 2 to 5 pups, and births occur primarily during the warmer seasons.
After a gestation period of around 11 weeks, the pups are born blind and helpless.
They are weaned at 49 to 63 days and become integrated into the social structure, learning survival skills such as foraging and sentry duty.
- Gestation Period: 11 weeks
- Litter Size: 2-5 pups
- Weaning: 49-63 days
Social Structure and Communication
Meerkats are gregarious and live in closely knit social groups called mobs, typically consisting of 20-50 individuals.
They exhibit a range of communicative behaviors, including vocalizations for different purposes.
Close calling allows them to remain in contact while foraging.
Moreover, there’s a hierarchy within the group, with a dominant female and male leading the mob.
Meerkats engage in various social activities such as grooming each other to reinforce social bonds.
A fascinating aspect is the sentry duty, where one meerkat acts as a guard to watch for predators while the others forage.
This behavior is a testament to the cooperative and social nature of these animals.
- Group Name: Mob
- Group Size: 20-50 individuals
- Key Behaviors: Close calling, grooming, sentry duty

The impacts of social and ecological factors on foraging groups are also intriguing, as discussed here in detail about the spatial structure of foraging meerkat groups.
The cohesion within these groups reveals much about their intricate social lives, making meerkats an endlessly intriguing subject of study.
Habitat and Diet
Meerkats are intriguing creatures known for their social structure and adaptability.
Endemic to Southern Africa, they have evolved to thrive in some of the most challenging habitats on the continent.
Their diet is diverse and reflects their opportunistic foraging behavior.
Regional Distribution
Meerkats call the open country of Southern Africa home, specifically the arid regions of South Africa, where they can often be spotted in the Kalahari Desert.
The desert’s extreme temperature variations and limited water availability have shaped the meerkat’s foraging habits and dietary preferences.
In search of food, meerkats forage in grasslands which offer rich feeding grounds.
They are omnivores, with their diet including a variety of insects, spiders, beetles, and scorpions, which provide crucial hydration.
Some studies, such as Diet and foraging behaviour of group‐living meerkats, Suricata suricatta, in the southern Kalahari, indicate that their diet is highly diversified and changes based on availability.
Termite mounds are hotspots for meerkat activity.
Not only do termites serve as a significant part of their diet, but the mounds also offer a lookout point to scan for predators.
Meerkats are known to dig for their prey, and their interactions with termite mounds also highlight their preference for certain microhabitats, discussed in The development of foraging microhabitat preferences in meerkats.
Their foraging isn’t limited to insects and small arthropods; meerkats are also fond of plant matter.
During certain times of the year when fruits are available, they capitalize on these sweet treats to supplement their diet.
Moreover, the consumption of eggs adds a valuable protein source to their dietary repertoire, although it’s a less common food item.
Despite the harsh conditions of their desert habitat and the scarcity of water, meerkats rarely drink water directly.
They extract most of the moisture they need from their food, which is an astonishing adaptation to living in such a dry environment.
This adaptability to an arid yet ecologically complex environment underlines the fascinating lives these small but resilient mammals lead.
Their ability to forage effectively under such conditions highlights the exceptional traits that have allowed meerkats to not just survive, but flourish in the African wilderness.
Conservation and Interaction with Humans
Meerkats, members of the mongoose family, have a curious relationship with humans, ranging from observational research to their appeal as exotic pets.
This interaction impacts both their conservation efforts and their behavioral ecology.
Threats and Conservation Status
Meerkats are classified by the International Union for Conservation of Nature (IUCN) as “Least Concern,” indicating that they are not currently at risk of extinction.
However, they face various threats including habitat loss due to human expansion, predation by eagles, jackals, hawks, falcons, and snakes, and illegal pet trade.
Their habitats, mainly the arid, open areas of southern Africa, are critical for their survival, offering both food sources and protection against predators.
The structure of their social systems, where meerkats live in groups called mobs, helps them protect one another.
In their tight-knit groups, meerkats often stand sentry to warn against predators like snakes and birds of prey.
Human interaction has both positive and negative effects on meerkats.
While research has shown that meerkats can become habituated to human presence, leading to insightful studies on their social dynamics and learning behaviors, there is a concern that increased human contact may alter their natural behaviors.
Meerkats have also gained popularity as pets, which could further threaten their wild populations.
Conservation assistance, education, and sustainable ecotourism are pivotal in ensuring that fascination with these creatures does not lead to detrimental consequences for their populations.
