How many baby Naked mole-rats are in a litter?
A Naked mole-rat (Heterocephalus glaber) usually gives birth to around 11 babies.With 4 litters per year, that sums up to a yearly offspring of 44 babies.
Each of those little ones spend around 70 days as a fetus before they are released into the wild. Upon birth, they weight 1 grams (0 lbs) and measure 1.3 cm (0′ 1″). They are a member of the Bathyergidae family (genus: Heterocephalus). An adult Naked mole-rat grows up to a size of 13 cm (0′ 6″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
The naked mole-rat (Heterocephalus glaber), also known as the sand puppy, is a burrowing rodent native to parts of East Africa. It is closely related to the blesmols and is the only species in the genus Heterocephalus of the family Heterocephalidae. The naked mole-rat and the Damaraland mole-rat (Fukomys damarensis) are the only known eusocial mammals, the highest classification of sociality. It has a highly unusual set of physical traits that allow it to thrive in a harsh underground environment and is the only mammalian thermoconformer, almost entirely ectothermic (cold-blooded) in how it regulates body temperature.The naked mole-rat lacks pain sensitivity in its skin, and has very low metabolic and respiratory rates. While formerly considered to belong to the same family as other African mole-rats, Bathyergidae, more recent investigation places it in a separate family, Heterocephalidae. The naked mole-rat is also remarkable for its longevity and its resistance to cancer and oxygen deprivation.
