Naked Mole Rats

They say to not judge a book by its cover, but they might need a more convincing adage to keep us from judging the naked mole rat. Though a little hard to look at, these rodents have a lot more going for them than their horror movie-worthy appearance.


Naked mole rats are native to East Africa, living in elaborate underground burrows and tunnels that they dig with their large teeth (their lips are behind these teeth to prevent dirt from getting in their mouths). Their small bodies – 3 to 4 inches long and 30-35 grams – and short legs are ideal for navigating cramped tunnels; they can scurry quickly both backward and forward.

Mole rats rarely leave their burrows: their mostly hairless, almost pigment-less bodies don’t fair well in the sun and their weak, beady eyes give them poor visual acuity. Fittingly, mole rats live mainly on tubers – starch-rich vegetables that grow underground. Additionally, mole rats have naturally low metabolisms and eat relatively infrequently; they can reduce their metabolisms even further when food is scarce.
