A meerkat clan often contains about 20 meerkats at a time, but some meerkat superfamilies have been known to have had 50 or more meerkat members. Mobs of meerkats fiercely attack snakes that may come near them, often killing a few. Meerkat, burrowing member of the mongoose family found in southwestern Africa that is unmistakably recognizable in its upright ‘sentinel’ posture as it watches for predators. There are three subspecies which are majoriae, iona and siricata. In addition to being small, pups are also blind, deaf and almost hairless. Learn about meerkat habitat and find out about the meerkat hunt and meerkat diet. The entrances, 15 cm (5.9 in) in diameter, are created by digging at an angle of 40 degrees to the surface; the soil accumulated as a result can slightly increase the height of burrow sites. They hunt by scent, and often dig out soil or turn over stones to uncover hidden prey. [11], The meerkat is listed as Least Concern on the IUCN Red List. Meerkats will also engage in power play, seeking to improve the position of their offspring in the group, subordinates may kill the offspring of senior members of the gang. The habitat of the meerkat. Photograph by Beverly Joubert, Nat Geo Image Collection, https://www.nationalgeographic.com/animals/mammals/m/meerkat.html. During winter, it balances heat loss by increasing the metabolic heat generation and other methods such as sunbathing. The meerkat genetically diverged from the rest of the clade 22.6–15.6 mya. Members of a gang will work together when a snake is spotted and they will jointly claw and bite it until it either escapes or is killed, however one meerkat will rarely do this when it is on its own. [2], Meerkats are highly vigilant, and frequently survey their surroundings by turning their heads side to side; some individuals always stand sentry and look out for danger. When mating occurs between meerkat relatives it often results in negative fitness consequences (inbreeding depression), that affect a variety of traits such as pup mass at emergence from the natal burrow, hindleg length, growth until independence and juvenile survival. Females, often the heaviest ones, try to achieve dominance over the rest in many ways such as fierce competition or taking over from the leader of the pack. (Image credit: Cleveland Metroparks Zoo.). Their tails add another 7.5 to 9.5 inches (19 to 24 cm) to their length. If you attempt to make a pet out of a meerkat, it will probably urinate on you to mark you as theirs and will even bite strangers who come close to you. [21] Raptors such as bateleurs, martial eagles, tawny eagles, and pale chanting goshawks are major aerial predators; on the ground, meerkats may be threatened by bat-eared foxes, black-backed jackals, and Cape foxes. Fathers and siblings help to raise meerkat young, teaching them to play and forage and alerting them to the ever present danger from above. They use a broad variety of calls to communicate among one another for different purposes, for example to raise alarm on sighting a predator. Once the female has submitted to the male, copulation takes place. This is possibly because the survival of female pups is more beneficial to female helpers as females are more likely to remain in their natal pack. [14] A 2009 phylogenetic study of the family Herpestidae split into two lineages around the Early Miocene (25.4–18.2 mya)—eusocial and solitary mongooses. Meerkats occur in several protected areas such as the Kgalagadi Transfrontier Park and the Makgadikgadi National Park. The meerkat that stands on guard will produce a variety of sounds when a predator is spotted depending on the type of predator spotted. The nonbreeding members of the pack help substantially with juvenile care, for instance they feed the pups and huddle with them for warmth. Meerkats are catlike carnivores that are part of the civets and mongoose family. When they are four weeks old, they will begin to go with the group to forage, and for their first 49 to 63 days will be fed by the helpers, at the same time being taught how to get their own food. The higher the urgency, the faster they have been seen to react. These large underground networks comprise two to three levels of tunnels up to 1.5 m (4.9 ft) into the ground; the tunnels, around 7.5 cm (3.0 in) high at the top, become broader after descending around a metre. Normally there will also be one male and other young adult meerkats that stay behind so as to help in taking care of the pups. [2][11] The soft coat is light grey to yellowish brown with alternate, poorly defined light and dark bands on the back. [21] Dispersed females travel longer than coalitions, and tend to start groups of their own or join other similar females; they aim for groups of emigrant males or those without a breeding female. everyone in the mob participates in gathering food, keeping a look out for predators and taking care of the babies. [33][34][35], The complexity of calls produced by different mongooses varies by their social structure and ecology. Its head is mostly white and the underparts are covered sparsely with dark reddish brown fur, with the dark skin underneath showing through. The phylogenetic relationships of the meerkat are depicted as follows:[15], Ethiopian dwarf mongoose (Helogale hirtula), Alexander's kusimanse (Crossarchus alexandri), Ichneumia, Cynictis, Paracynictis, Rhynchogale, Bdeogale, Galerella and Egyptian mongoose (Herpestes ichneumon), Asian Herpestes, long-nosed mongoose (H. naso) and marsh mongoose (Atilax paludinosus), The meerkat is a small mongoose of slim build characterised by a broad head, large eyes, a pointed snout, long legs, a thin tapering tail and a brindled coat pattern. These complex habitats have many tunnels which lead to numerous sleeping chambers. They can dig their own body weight of dirt within a few seconds and their high endurance enables them to build elaborate tunnels. Habitat: Desert Range: There are few animals on Earth who work as well together as meerkats. Meerkats are eusocial, and form packs of two to 30 individuals each that occupy home ranges around 5 km2 (1.9 sq mi) large. Meerkats are mainly insectivorous, eating insects such as scorpions (they are immune to the venom), beetles, spiders, crickets, centipedes, millipedes and worms. Four meerkat babies have joined the baby boom success list at Belfast Zoo! They often stand on their rear legs and gaze alertly over the southern African plains where they live. They live in mobs, or can also be referred to as gangs, and no matter how much you like them you would probably never want to make them a pet. The babies, called pups, are born underground, where they are safe from predators. The young ones, called pups are born in the underground burrows and are born when they are undeveloped; usually a litter has 1 to 4 pups, however on average there are 3 pups in a litter. Burrows have moderated internal temperatures and provide a comfortable microclimate that protects meerkats in harsh weather and at extreme temperatures. Females give birth to one to eight babies at a time, but it is more common for meerkat mothers to have three to four offspring at a time. However, instead of allowing pups to learn by trial and error and risk receiving a potentially life-threatening sting, mothers will cut the tail off of a scorpion before feeding the arachnid to her young, according to a 2006 study published in the journal Science. A group of meerkats is called a mob of meerkats, a gang of meerkats or a clan of meerkats. Though yellow mongooses are also insectivores like meerkats, competition for prey is minimal as yellow mongooses are less selective in their diet. (adsbygoogle = window.adsbygoogle || []).push({}); Their vision is adapted to their environment and is binocular, similar to the ones that cats have and this enables them to see objects that are far really well. However due to the heat of the afternoon sun in dry and desert areas, they retreat back to their underground homes in the afternoon. They live in rock crevices in stony, often calcareous areas, and in large burrow systems in plains.

There are currently no major threats to the animals, and their populations are doing well. Offspring born from non-dominant pairs are often killed by the dominant pair.
