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. Yes, they live in large family groups called clans, mobs, or gangs.
Courtship behaviour is limited; the male fights with his partner, getting hold of her by her snout.
Primarily insectivorous, meerkats feed heavily on beetles and lepidopterans, though they also include amphibians, arthropods, small birds, reptiles, and plant material in their diet. These hunters will skillfully disable the venomous predator, remove the venom gland, and eat the rest. It is absent from true deserts, montane regions and forests. [2][11] Consequently, meerkats spend considerable time in burrows; they are active mainly during the day and return to burrows after dark and often to escape the heat of the afternoon. Their tan and brown fur helps them to blend into the desert and hide from predators such as eagles. Taxonomy: Members of the
[52], This article is about the mammal. Mating behaviour has been studied in captive individuals. Females become sexually mature at two to three years of age.
[26][27] Some subordinate meerkats will even kill the pups of dominant members in order to improve their own offspring's position. [42] Sometimes helpers favour their own needs over those of pups and decide not to feed them; this behaviour, known as "false-feeding", is more common when the prey is more valued by the meerkat. 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. Martial eagles and jackals. Captive meerkats include plenty of fruits and vegetables in their diet, and also kill small mammals by biting the backs of their skulls. [22], Packs live in rock crevices in stony areas and in large burrow systems in plains. Commonly found in arid, open habitats with little woody vegetation, meerkats occur in southwestern Botswana, western and southern Namibia, northern and western South Africa; the range barely extends into southwestern Angola.
the mother feeds. It is smaller than most other mongooses except the dwarf mongooses (genus Helogale) and possibly Galerella species. ground squirrels and yellow mongooses. thirty members, is called a "mob" or a "gang.". This association is beneficial to all the species as it saves time and efforts spent in making separate warrens. A pack may shift to another burrow if the dominant female has little success finding prey in an area. [31] Short-range 'close calls' are produced while foraging and after scanning the vicinity for predators.
times annually if food supply is depleted. It is characterised by a broad head, large eyes, a pointed snout, long legs, a thin tapering tail, and a brindled coat pattern. [50] In South Africa meerkats are used to kill rodents in rural households and lepidopterans in farmlands. [2], Meerkats have been widely portrayed in movies, television and other media. Diet of the Meerkat. They hunt by scent, and often dig out soil or turn over stones to uncover hidden prey. A study recorded 12 different types of call combinations used in different situations such as guarding against predators, caring for young, digging, sunbathing, huddling together and aggression. The biggest threat to Meerkats are Birds of Prey such as Hawks and Eagles that can spot these animals from high above their heads, along with ground-dwelling predators such as Snakes that hunt them on the ground. [11][21] A study showed that nearly half of the litters of dominant females, especially those born later in the breeding season were nursed by subordinate females, mostly those that were or recently had been pregnant.
They dig large networks of underground tunnels where they stay during the night. Morongo Valley, CA 92256 They suggested there were four local meerkat races in the Cape and Deelfontein, Grahamstown, Orange River Colony and southern Transvaal, and Klipfontein respectively. As such, subordinate individuals might disperse to other packs to find mates during the breeding season.
The burrows that they dig are good for protection, but they also help them to keep cool from the hot desert sun. Meerkat Predators.
With no significant threats to the populations, the meerkat is listed as Least Concern on the IUCN Red List. Note the banded pattern, the big eye circles and the thin tail. [11][21], Encounters between members of different packs are highly aggressive, leading to severe injuries and sometimes deaths. [9] The present scientific name Suricata suricatta was first used by Oldfield Thomas and Harold Schwann in 1905 when they described a specimen collected at Wakkerstroom. They typically have around 20 members, but sometimes grow to as many as 50 members. indicate different predators. [11][21] Some helpers contribute to all activities more than others, though none of them might be specialised in any of them.
All these calls differ in their acoustic characteristics, and can evoke different responses in the 'receivers' (meerkats who hear the call); generally the greater the urgency of the scenario in which the call is given, the stronger is the response in the receivers. [45] The mother runs around with prey in her mouth, prompting her pups to catch it. Many often team up in 'coalitions' for as long as two months and travel nearly 5 km (3.1 mi) a day on twisted paths. Transience: Mob moves several Helplessness: Born with eyes and Meerkats are eusocial, and form packs of two to 30 individuals each that occupy home ranges around 5 km2 (1.9 sq mi) large. For other uses, see, "Meerkats" redirects here. the others forage or nap. The solitary mongoose lineage comprises two clades including species such as Meller's mongoose (Rhynchogale melleri) and the yellow mongoose (Cynictis penicillata).
Feet: Non-retractable claws.
[40] Infants make continuous sounds that resemble bird-like tweets, that change to a shrill contact call as they grow older. Predators of the meerkat include snakes, jackals, and birds of prey. List of mammals from the Wakkerstroom district, south-eastern Transvaal", "Molecular phylogeny of the Herpestidae (Mammalia, Carnivora) with a special emphasis on the Asian, "Burrow usage patterns and decision-making in meerkat groups", "Early growth, dominance acquisition and lifetime reproductive success in male and female cooperative meerkats", "A genetic analysis of breeding success in the cooperative meerkat (, "Subordinate male meerkats prospect for extra-group paternity: alternative reproductive tactics in a cooperative mammal", "Infanticide by subordinates influences reproductive sharing in cooperatively breeding meerkats", "Segmental structure in banded mongoose calls", "All clear? The meerkat genetically diverged from the rest of the clade 22.6–15.6 mya. There is a social hierarchy—generally dominant individuals in a pack breed and produce offspring, and the nonbreeding, subordinate members provide altruistic care to the pups. Meerkat Predators and Threats Due to the small size of the Meerkat, they are natural prey to numerous animal species that are both on the ground and in the air. The Meerkat is a small mammal that is part of the mongoose family. 'Meerkat' derives from the Dutch name for a kind of monkey, which in turn comes from the Old High German mericazza, possibly as a combination of meer ('lake') and kat ('cat'). [11][21], After a gestation of 60 to 70 days, a litter of three to seven pups is born. Competitiveness: Meerkats are very territorial Dwelling: Grass-lined burrows that are shared with
Mothers give out shrill, repetitive calls to ensure their pups follow them and remain close together. Meerkats use a system that utilizes their numbers and cooperation.
