Big-eared fox (scientific name: Otocyon megalotis) has bat-like ears , up to 14 cm long. In fact, the species name "megalotis" is derived from the Greek words "mega" and "otus", meaning big ears. A pair of big ears plays an important role in many aspects of communication, finding food, and more. Coat coloration varies from pale yellow to dark honey, depending on age and area of discovery. The muzzle is larger than that of other foxes, grey-black in colour, with grey-white tips on both sides. High fangs for fast and efficient chewing of insect food to aid digestion.

Big-eared foxes are named after their pair of huge ears, 114-135 mm long, mostly tan hair, grayish-white throat and belly, and The outer edge is like wearing a "mask" like a brown bear. The calf, claws, and tip of the tail are black. In addition to a pair of large ears, its unique dentition is also different from other foxes. The big-eared fox has 46-50 teeth. , more than other heterodentate mammals with placenta. Other canines have no more than two upper molars and three lower molars, and the big-eared fox has at least three upper molars and four lower molars, and a large stepped digastric protrusion on the lower jaw, which facilitates quick chewing of insects.

The adult fox head is 46-66 cm long and weighs 3.0-5.3 kg. The limbs are shorter.

Inhabits dry grasslands and savannahs, preferring short-grass areas. Live in caves left by self-built or other animals. Caves generally have multiple entrances and dens, as well as tunnels that are several meters long.

Serengeti Plains, Big Eared Fox 85% of their activity occurs at night, in South Africa, they burrow out during the day in winter and evening in summer. Research in the Serengeti Plains found that the big-eared fox family had an exclusive territory of roughly 0.25-1.5 square kilometers, with urine marking the territorial boundaries. Each family includes a pair of parents and their offspring, who forage and rest together, often lie down and touch each other, groom each other, and play and help each other. In South Africa, large-eared foxes have widely overlapping family territories with little or no territorial markings, sometimes 2-3 burrows within a few hundred meters, and population densities of up to 10 per square kilometer, which may be incompatible with locally suitable soil or vegetation. related. Large-eared foxes live in groups that help capture more termites, enhance predation detection, and provide opportunities for offspring to learn what to eat and how to hunt by imitation.

There are similarities between play and escape behavior among young foxes, as adult foxes often demonstrate escape rather than fight.

The diet of the big-eared fox consists mainly of insects and other arthropods, occasionally small rodents, Lizards, eggs, chicks and plants; termites, mayfly beetles make up 80% of the food source. Ground-feeding termites are eaten by passing big-eared foxes. They get a lot of water from the body fluids of these insects. Big-eared foxes are often seen around large herbivores such as wildebeest, zebras and buffalo, and use their large ears to listen for beetle larvae. Generally foraging alone, in places where insects are abundant, big-eared foxes will also gather in large numbers. In fact, group foraging captured more termites than solo foraging at the same time.
