These bats have mostly hairless bodies and fold their wings into pouches of skin along their bodies when at rest. [3] These are among the largest insectivorous bats, weighing up to 135 grams. [4] There are two species in this genus: [2] Lesser naked bat Cheiromeles parvidens; Hairless bat Cheiromeles torquatus
Humans are the only primate species that have undergone significant hair loss and of the approximately 5000 extant species of mammal, only a handful are effectively hairless. This list includes elephants, rhinoceroses, hippopotamuses, walruses, some species of pigs, whales and other cetaceans, and naked mole rats. [5]
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
There are no indications of the colour and skin texture of the animal because no skin impressions or mummies are known. Most life restorations show the creature's skin as thick, folded, grey, and hairless, based on modern rhinoceroses. Because hair retains body heat, modern large mammals such as elephants and rhinoceroses are largely hairless.

The species does not meet any of the criteria that would categorize it as risking extinction but it is likely to do so in the future. LC: Least concern: There are no current identifiable risks to the species. DD: Data deficient: There is inadequate information to make an assessment of the risks to this species.
There are currently 1,258 genera, 161 families, 27 orders, and around 5,937 recognized living species of mammal. [1] Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families.
