The sand cat (Felis margarita) is a small wild cat that inhabits sandy and stony deserts far from water sources. With its sandy to light grey fur, it is well camouflaged in a desert environment. Its head-and-body length ranges from 39–52 cm (15–20 in) with a 23–31 cm (9.1–12.2 in) long tail. Its 5–7 cm (2.0–2.8 in) short ears are set low on the sides of the head, aiding detection of prey moving underground. The long hair covering the soles of its paws insulates its pads against the extreme temperatures found in deserts. The first sand cat known to scientists was discovered in the Algerian Sahara and described in 1858. To date, it has been recorded in several disjunct locations in Western Sahara, Morocco, Algeria, Libya, Niger, Chad, Egypt, the Arabian Peninsula and the Middle East. In Central Asia, it was first recorded in the Karakum Desert in 1925. The large gap between these two regions of its global range was partially closed in 1948, when a sand cat skin was found in an oasis of the Rub' al Khali in Oman. It is discontinuously distributed in the deserts of the Arabian Peninsula and the Middle East. In the early 1970s, sand cats were caught in southwestern Pakistan and exported to zoos worldwide. Due to its wide distribution and large population, it is listed as Least Concern on the IUCN Red List. The sand cat usually rests in underground dens during the day and hunts at night. It moves 5.4 km (3.4 mi) on average at night in search of small rodents and birds. It also kills and consumes venomous snakes. In spring, the female gives birth to two to three kittens, which become sexually mature around the age of one year. The sand cat's ecological requirements are still poorly understood, as only a few in-depth studies targeting wild sand cat populations have been conducted.
Taxonomy
Felis margarita was the scientific name proposed by Victor Loche in 1858 who first described a sand cat specimen found in the area of "Négonça" in the northern Algerian Sahara. This holotype specimen appears to have been lost. The species was named after the French General Jean Auguste Margueritte. In the 20th century, the following zoological specimens of sand cats were described:
Eremaelurus thinobius was proposed as a species by Sergey Ognev in 1926. The specimen had been collected in the eastern Karakum Desert in Turkmenistan. In 1938, Reginald Innes Pocock also considered it a species, but subordinated it to the genus Felis using the scientific name Felis thinobius. Later he considered it a sand cat subspecies, which to date is widely recognised. F. m. meinertzhageni proposed by Pocock in 1938 was a sand cat skin from the Algerian Sahara. F. m. aïrensis proposed by Pocock in 1938 was a female specimen collected in the Aïr Mountains in 1937. F. m. scheffeli proposed by German zoologist Helmut Hemmer in 1974 was described on the basis of seven sand cats that had been captured alive in Pakistan's Nushki desert. F. m. harrisoni proposed by Hemmer, Grubb and Groves in 1976 was described on the basis of a skin and skull of an adult male sand cat captured in 1967 in Umm al Samim, Oman. In 1974, F. m. margarita, F. m. thinobia and F. m. scheffeli were temporarily recognized as valid taxa. At the time, it was considered possible that sand cats eventually recorded in Afghanistan and Iran might constitute distinct subspecies. In 2005, F. m. margarita, F. m. thinobia, F. m. scheffeli and F. m. harrisoni were recognised as valid taxa by W. Chris Wozencraft, who considered F. m. meinertzhageni and F. m. aïrensis synonyms of the nominate subspecies F. m. margarita. The Cat Classification Task Force of the Cat Specialist Group reviewed the existing information and in 2017 recognized only two subspecies based on morphological differences, namely:
Felis margarita margarita, also called the Saharan sand cat, occurs in North Africa. It is smaller in size with brighter, more yellow fur, with more pronounced markings and 2–6 rings on the tail. Felis margarita thinobia, also called the Turkestan sand cat, Arabian sand cat, and Pakistan sand cat, it occurs in West and Central Asia. It is larger in size with less pronounced markings, a darker, more greyish coat, and only 2–3 rings on the tail. Analysis of mitochondrial DNA of 47 individuals from across the sand cat's range showed that their haplotypes differed only by one to three base pair mutations. This low degree of genetic differentiation between the African and Asian sand cats indicates that the Sinai Peninsula may have been a barrier to gene flow.
Phylogeny Phylogenetic analysis of the nuclear DNA in tissue samples from all Felidae species revealed that the evolutionary radiation of the Felidae began in Asia in the Miocene around 14.45 to 8.38 million years ago. Analysis of mitochondrial DNA of all Felidae species indicates a radiation at around 16.76 to 6.46 million years ago. The sand cat is part of an evolutionary lineage that is estimated to have genetically diverged from the common ancestor of the Felis species around 4.44 to 2.16 million years ago, based on analysis of their nuclear DNA. Analysis of their mitochondrial DNA indicates a genetic divergence of the Felis species at around 6.52 to 1.03 million years ago. Both models agree that the jungle cat (F. chaus) was the first Felis species that diverged, followed by the black-footed cat (F. nigripes) and then the sand cat. It migrated into Africa, possibly during Pleistocene glaciation events. Migration was likely facilitated by extended periods of low sea levels between continents. A fossil jaw and other skeletal remains of a sand cat were excavated in a Late Pleistocene cave in El Harhoura located near Temara in Morocco.
