Naked mole-rats can live longer than any other rodent, with lifespans in excess of 37 years; the next longest-lived rodent is the African porcupine at 28 years. [ 38 ] [ 39 ] [ 40 ] The mortality rate of the species does not increase with age, and thus does not conform to that of most mammals (as frequently defined by the Gompertz-Makeham law ...
Among mammals, two species in the rodent group Phiomorpha are eusocial, the naked mole-rat (Heterocephalus glaber) and the Damaraland mole-rat (Fukomys damarensis), both of which are highly inbred. [41] Usually living in harsh or limiting environments, these mole-rats aid in raising siblings and relatives born to a single reproductive queen.
[19] [20] For example, the sponge-dwelling shrimp depend upon the sponge's feeding current for food, termites depend upon dead, decaying wood, and naked mole rats depend upon tubers in the ground. [5] [13] [21] Each of these resources has patchy distributions throughout the environments of these animals. This means there is a high cost to ...
It may look like a whiskered cocktail sausage, but the naked mole rat's incredible biology may one day improve countless lives. Meet the naked mole-rat: impervious to pain and cancer, and lives ...
The closely related subfamily Spalacinae consists of mole-like rodents found in Africa and the Middle East; these are also myomorphic rodents. The family Bathyergidae , or African mole-rats (including the well-known naked mole-rat ), belong to the other major division of the rodents, the hystricomorphs.
Mole-rat or mole rat can refer to several groups of burrowing Old World rodents: Bathyergidae, a family of about 20 hystricognath species in six genera from Africa also called blesmols. Heterocephalus glaber, the naked mole-rat. Spalacidae, a family of about 30 muroid species in six genera from Eurasia and northeast Africa, including:
It's hard to say why this flu season is particularly intense, the experts note. It could be due to a combination of factors, says Yancey. “This (flu season) just feels much longer. ...
Two potential examples of primitively eusocial mammals are the naked mole-rat and the Damaraland mole-rat (Heterocephalus glaber and Fukomys damarensis, respectively). [66] Both species are diploid and highly inbred , and they aid in raising their siblings and relatives, all of whom are born from a single reproductive queen; they usually live ...
