The fennec fox (Vulpes zerda) is a small crepuscular fox native to the deserts of North Africa, ranging from Western Sahara and Mauritania to the Sinai Peninsula. [1] Its most distinctive feature is its unusually large ears, which serve to dissipate heat and listen for underground prey.
[22] Trut reported that female foxes heterozygous for the gene controlling the star pattern also influenced the number of male pups, increasing the number of males over the expected 50%. As the fox experiment has progressed over time, it was found that in general the number of male pups increased over the expected 50% to approximately 54%. [23]
A hybrid of domestic dog and pampas fox. Crossings between canids of a different genus is extremely rare. In 2021, a female canid with unusual phenotypic characteristics was found in Vacaria City, Rio Grande do Sul, Brazil. DNA analysis indicates that the canid was a hybrid between a pampas fox and a domestic dog. [33]
The length, color and density of the fur of fox species differ. Fennec foxes (and other desert-adapted fox species such as Vulpes macrotis) have large ears and a short coat to keep the body cool. [21] On the other hand, the Arctic fox has small ears and a thick, insulating coat to keep the body warm. [22]
Cats of Africa, which features African lions and fennec foxes, is another African themed habitat opened in 2003. [2] Built on a hillside, the area's fennec fox exhibit is at the top of the slope, with the lion exhibit on the slope itself. The lions are visible from a platform near the fennec fox exhibit.
The common raccoon dog (Nyctereutes procyonoides), also called the Chinese or Asian raccoon dog to distinguish it from the Japanese raccoon dog, is a small, heavy-set, fox-like canid native to East Asia. Named for its raccoon-like face markings, it is most closely related to foxes.
The fennec fox's large ears help keep it cool: when the blood vessels dilate, blood from the body cycles in and dissipates over the expanded surface area. [1]A xerocole (from Greek xēros / ˈ z ɪ r oʊ s / 'dry' and Latin col(ere) 'to inhabit'), [2] [3] [4] is a general term referring to any animal that is adapted to live in a desert.
Dogxim, or Graxorra in Portuguese, was a female canid hybrid between a Pampas fox and a domesticated dog that was discovered in Brazil during 2021. [1] The canid showed a mixture of fox and dog behaviours, [2] and a team of geneticists led by Thales Renato Ochotorena de Freitas and Rafael Kretschmer announced in 2023 that she was a distinct hybrid genetically that "represents the first ...
