Bat Eared Fox Profile
As pets, they are often fed meat and greens. These foxes have been stored indoors by homeowners. But, much like different fox species, bat-eared foxes need an escape-proof enclosure. Beware of digging and scent marking with this fox species, too.
The bat-eared foxes can outrun lions and cheetahs, which suggests, they will run at a pace sooner than 70 miles per hour.
Surviving on an all-insect diet required a number of variations within the bat-eared fox. In addition to their massive and highly effective ears, bat-eared foxes have specialised additional teeth for chewing up bugs, and their decrease jawbone is designed to open and shut quickly
A male Bat Eared Fox is named a “dog,” a feminine is named a “vixen” and a child is named a “kit.” The bat-eared fox diet consists primarily of bugs comparable to ants and termites, within the wet season and mice within the dry season. Bat-eared foxes can use their massive ears to find beetle larvae buried beneath the ground.
Bat Eared Fox Description
The bat-eared fox’s name comes from its huge ears, which are 114 to 135 mm long. The body is mostly yellow-brown; the throat and underparts are pale; the outsides of the ears, raccoon-like “face-mask,” decrease legs, feet, and tail tip are black.

Bat Eared Fox has more teeth than some other heterodont placental mammal with a total between 46 and 50 (Nowak, 1983). Whereas in all different canids there are not any more than two higher and three decrease molars, the bat-eared fox has at the least three higher and 4 decrease molars.
On the decrease jaw, a big step-like protrusion anchors the big digastric muscle that’s used for speedy chewing of bugs. The legs are comparatively quick.
Bat-eared foxes are comparatively small canids, ranging in weight from three kg to five.3 kg. Head and body size is 46–66 cm, tail size is 23–34 cm, shoulder height is 30–40 cm, and the notably massive ears are 11–13 cm long.
Generally, the pelage of the Otocyon megalotis is tan-colored, with grey agouti guard hairs, giving its grizzled look, showing more buff on the edges. The undersides and throat are pale. The limbs are darkish, shading to darkish brown or black at their extremities.
The muzzle, the tip and upper side of the tail, and the facial masks are black. The insides of the ears are white. Individuals of the East African subspecies, O. m. virgatus, have a tendency towards a buff pelage with darkish brown markings, versus the black of O. m. megalotis.
Proportionally massive ears of bat-eared foxes, an attribute shared by many different inhabitants of scorching, arid climates, assist to distribute warmth. They additionally assist in finding prey.
Bat Eared Fox Range and distribution
The bat-eared fox has a disjointed range of distribution throughout the arid and semi-arid areas of Eastern and Southern Africa, in two allopatric populations (representing every of the acknowledged subspecies) separated by roughly 1,000 km.
Subspecies O. m. virgatus extends from southern Sudan, Ethiopia, and Somalia, by way of Uganda and Kenya to southwestern Tanzania; O. m. megalotis happens within the southern part of Africa, starting from Angola by way of Namibia and Botswana to South Africa, and extends as far east as Mozambique and Zimbabwe, spreading into the Cape Peninsula and towards Cape Agulhas. Home ranges range in size from 0.3 to 3.5 square km. There are not any confirmed observations in Zambia.
Bat Eared Fox Habitat
Bat-eared foxes, Otocyon megalotis are tailored to arid or semi-arid environments. They have generally discovered briefly in grasslands, in addition to the more arid areas of the savannas, alongside woodland edges, and in open acacia woodlands.
Otocyon megalotis prefers naked ground and areas the place grass is stored short by grazing ungulates. It tends to hunt in these quick grass and low shrub habitats. However, it does enterprise into areas with tall grasses and thick shrubs to cover when threatened.
Bat-eared foxes are present in arid grasslands and savannas, preferring areas the place the grass is brief. They are successful diggers and dwell in dens that might be dug by the foxes themselves or these left by different animals comparable to aardvarks.
Dens have a number of entrances and chambers and a number of other meters of tunnels. A family could have a number of dens in its house range.
In addition to elevating their younger in dens, bat-eared foxes use self-dug dens for shelter from excessive temperatures and winds. They additionally lie underneath acacia timber in South Africa to hunt shade throughout the day.
Bat Eared Fox Dentition
The teeth of the bat-eared fox are a lot smaller and lowered in shearing floor formation than teeth of different canid species. This is an adaptation to its insectivorous diet.
The bat-eared fox is an old species that was extensively distributed within the Pleistocene period. The teeth will not be the bat-eared fox’s solely morphological adaptation for its diet.
On the decrease jaw, a step-like protrusion referred to as the subangular process, anchors the big digastric muscle to permit for speedy chewing. The digastric muscle can also be modified to open and shut the jaw 5 instances per second.
Bat Eared Fox Behavior
In the more northern areas of its range (around Serengeti), they’re nocturnal 85% of the time. However, around South Africa, they’re nocturnal solely in the summertime and diurnal throughout the winter.
Bat-eared foxes are extremely social animals. They usually dwell in pairs or teams, and residential ranges of teams both overlap considerably or little or no.
In southern Africa, bat-eared foxes dwell in monogamous pairs with kits, whereas these in eastern Africa could dwell in pairs, or in stable family teams consisting of a male and as much as three intently associated females with cubs. Individuals forage, play, and relax collectively in a gaggle, which helps in safety towards predators.
They interact in frequent and prolonged allogrooming periods, which serve to strengthen group cohesion, largely between mature adults, but additionally between younger adults and mature adults.
Bat Eared Fox Adaptation
Visual shows are essential in communication amongst bat-eared foxes. When they’re trying intently at one thing, the pinnacle is held high, eyes are open, ears are erect and dealing with ahead, and the mouth is closed.

When termites are plentiful, feeding aggregations of as many as 15 people from completely different households happen.
Individuals forage alone after family teams break in June or July and throughout the months after cub beginning.
Prey is situated primarily by auditory means, slightly than by odor or sight. Foraging patterns range between seasons and populations, and coincide with termite availability.
In eastern Africa, nocturnal foraging is the rule, whereas, in southern Africa, nocturnal foraging throughout summer slowly modifications to an almost solely diurnal pattern throughout the winter.
Foraging methods rely upon prey sort, but meals are commonly situated by strolling slowly, nose near the ground, and ears tilted ahead. It normally happens in patches, which match the clumped prey assets, comparable to termite colonies, that additionally happen in patches.
Groups are capable of forage on clumps of prey in patches as a result of they don’t struggle with each other for meals because of their degree of sociality and lack of territoriality.
Bat Eared Fox Diet
When this explicit species of termite will not be obtainable, their opportunistic diet permits all kinds of meals gadgets to be taken: they will devour different species of termites, different arthropods comparable to ants, beetles, crickets, grasshoppers, millipedes, moths, scorpions, spiders, and barely birds, small mammals, reptiles, and fungi (the desert truffle Kalaharituber pfeilii).
Berries, seeds, and wild fruit are also consumed. The bat-eared fox refuses to feed on snouted harvester termites, likely as a result of its not tailored to tolerate termites’ chemical protection.

Bat-eared foxes, Otocyon megalotis get hold of a lot of their water from the body fluids of those bugs. The termites usually feed on the grass above ground, the place they’re then eaten by the foxes.
Because massive herbivores comparable to wildebeest, zebra, and buffalo additionally feed on this grass, bat-eared foxes are normally discovered close to massive herds of those hoofed animals. Furthermore, bat-eared foxes are additionally related to these mammals since they eat the dung beetles that feed on and lay eggs within the ungulate’s feces.
The Otocyon megalotis use their massive ears to hear for beetle larvae gnawing their method out of the dung balls. Bat-eared foxes normally forage alone.
However, the place insect prey is plentiful, bat-eared foxes could happen in very high densities. They can really harvest more termites by foraging in a gaggle than in the event that they hunted individually over the identical ground at the same time.
To escape from predators, the bat-eared fox depends on speed and its unbelievable dodging means. It can successfully reverse course at a flat run without dropping pace.
Bat-eared foxes are inclined to predators all the way down to the size of jackals and eagles. Diurnal birds of prey typically symbolize the best risk for younger bat-eared foxes.
Bat Eared Fox Reproduction
Bat-eared foxes, Otocyon megalotis breed yearly, in self-dug dens. Pups’ eyes open at 9 days they usually emerge from the den at 17 days. Newborns are sparsely lined with grey underfur and alter to adult coloration by 4-5 weeks.
Offspring are suckled for 15 weeks before starting to forage with their parents. Pups are full-grown by 5 or 6 months. After reaching maturity, most disperse during the breeding season.
Some younger females could stay with their natal group and breed. Males take part in guarding, grooming, and enjoying with the younger as a lot as and even more than the mom.
Mating behavior has not been described within the wild, however, in a zoo, a pair mated 10 instances a day per week. The feminine confirmed no estrous swelling. The male adopted the feminine intently, licking her vulva and periodically mounted. After intromission, the pair remained tied, as in lots of canids.
The bat-eared fox is predominantly socially monogamous, though it has been noticed in polygynous teams. In distinction to different canids, the bat-eared fox has a reversal in parental roles, with the male taking over the vast majority of the parental care behavior.
Gestation lasts for 60–70 days and females give beginning to litters consisting of 1 to 6 kits. Beyond lactation, which lasts 14 to 15 weeks, males take over-grooming, defending, huddling, chaperoning, and carrying the younger between den sites.
Additionally, male care and den attendance charges have been proven to have a direct correlation with cub survival charges. The feminine forages for meals, which she makes use of to take care of milk manufacturing, on which the pups closely rely. Food foraged by the feminine will not be introduced back to the pups or regurgitated to feed the pups.
Pups within the Kalahari area are born September–November, and people within the Botswana area are born October–December. Young bat-eared foxes disperse and go away from their family teams at 5–6 months old and attain sexual maturity at 8–9 months.
The bat-eared fox, Otocyon megalotis has some business use for people. They are vital for harvesters’ termite inhabitants’ control because the termites are thought of as pests. They have additionally been hunted for his or her fur by Botswana natives.
Additional threats to populations embrace illness and drought that may hurt populations of prey; nonetheless, no main threats to bat-eared fox populations exist.
