FENNEC

Snakes are Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards.[3] These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, Dibamidae, and Pygopodidae). Living snakes are found on every continent except Antarctica, and on most smaller land masses; exceptions include some large islands, such as Ireland, Iceland, Greenland, the Hawaiian archipelago, and the islands of New Zealand, as well as many small islands of the Atlantic and central Pacific oceans.[4] Additionally, sea snakes are widespread throughout the Indian and Pacific oceans. More than twenty families are currently recognized, comprising about 520 genera and about 3,900 species.[5] They range in size from the tiny, 10.4 cm-long (4.1 in) Barbados threadsnake to the reticulated python of 6.95 meters (22.8 ft) in length.[7] The fossil species Titanoboa cerrejonensis was 12.8 meters (42 ft) long.[8] Snakes are thought to have evolved from either burrowing or aquatic lizards, perhaps during the Jurassic period, with the earliest known fossils dating to between 143 and 167 Ma ago.[9][10] The diversity of modern snakes appeared during the Paleocene epoch (c. 66 to 56 Ma ago, after the Cretaceous–Paleogene extinction event). The oldest preserved descriptions of snakes can be found in the Brooklyn Papyrus. Most species of snake are nonvenomous and those that have venom use it primarily to kill and subdue prey rather than for self-defense. Some possess venom that is potent enough to cause painful injury or death to humans. Nonvenomous snakes either swallow prey alive or kill by constriction.

Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. Ovine meat is called lamb when from younger animals and mutton when from older ones in Commonwealth countries, and lamb in the United States (including from adults). Sheep continue to be important for wool and meat today, and are also occasionally raised for pelts, as dairy animals, or as model organisms for science.

The camel is a kind of cloven-hoofed ungulates of the genus Camelus, with unique fat deposits on its back called "humps". Camels have been domesticated for a long time. As livestock, they provide food (milk and meat) and textiles (fiber and hair felt). Camels are working animals that are particularly suitable for desert habitats and are important means of transportation for passengers and goods. There are three types of camels in existence. Dromedary camels accounted for 94% of the world's camel population, and Bactrian camels accounted for 6%. The wild bactrian camel is an independent species and is now critically endangered. The term camel is also used informally in a broader sense, where the more correct term is "camelidae", which includes all seven species of camelid: the real camel (the above three species), and the "new Camelids of the world": llamas, alpacas, guanacos and vicunas. The word itself is derived from Latin: camelus and Greek: κάμηλος (kamēlos) from Hebrew, Arabic or Phoenician: gāmāl

Fennec fox (Vulpes zerda) is a small dusk fox native to the Sahara Desert, the Sinai Peninsula in Egypt, and the Arava and Negev deserts in Israel. Its most notable feature is its unusually large ears, which are used to dissipate heat. Fennec is the smallest canine. Its fur, ears and kidney functions have been adapted to the desert environment of high temperature and low water. In addition, its hearing is very sensitive to prey moving underground. Mainly eat insects, small mammals and birds. Fennel can live up to 14 years in captivity and about 10 years in the wild. Its main predators are Verreaux's eagle owls, jackals and other large mammals. The Fennec family digs caves in the sand for habitation and protection, which can reach an area of ​​120 square meters (1,292 square feet) and are adjacent to the caves of other families. The exact population is unknown, but it is estimated based on the frequency of sightings; these indicate that the fennec fox is not currently threatened with extinction. The knowledge of social interaction is limited to information collected from captive animals. The fur of the fennec fox is cherished by the indigenous people of North Africa. In some parts of the world, it is regarded as an exotic pet. Its name comes from the Arabic name of the species: fanak (فَنَك).
