Arctic, bat-eared and fennec are varieties of which member of the canine family?

The fennec fox is a small fox native to the Sahara Desert and the Sinai Peninsula. Its most distinctive feature is its unusually large ears, which serve to dissipate heat. The fennec is the smallest canid species. Its coat, ears, and kidney functions have adapted to the desert environment with high temperatures and little water. Also, its hearing is sensitive to hear prey moving underground. It mainly eats insects, small mammals, and birds.

The bat-eared fox is a species of fox found on the African savanna, named for its large ears, which, like the fennec, are used for thermoregulation. It has also been called a Sub-Saharan African version of a fennec fox. It is predominantly an insectivore that uses its large ears to locate its prey. About 80–90% of their diet is harvester termites. When this particular species of termite is not available, they feed on other species of termites and have also been observed consuming other insects.

The Arctic fox, also known as the white fox, polar fox, or snow fox, is a small fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic. It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. The Arctic fox preys on many small creatures such as lemmings, ringed seal pups, fish, and seabirds.

These foxes are in the dog subfamily 'Caninae', which is part of the 'Vulpes' genus. Other members include the red, cape, kit and corsac fox.
