Do naked mole-rats live in groups?

Naked mole-rats are eusocial, meaning they live in large colonies in which only one female breeds and the majority of workers (both males and females) spend their entire lives working for the colony.

Are naked mole-rats rats?

Naked mole rats live underground in the dry, arid regions of Ethiopia, Somalia and Kenya. These unique animals are rodents, but they are more closely related to porcupines and guinea pigs than they are to either moles or rats.

Are moles in the rat family?

They are part of the Rodent family. Moles aren’t blind, but they are colorblind and see very poorly. They can only see light and movement.

What did naked mole-rats evolve from?

Photo by Nikolai Barbel, CC BY-SA 3.0. For a while the general assumption seemed to be that the eusociality of the Naked mole-rat had evolved from the also eusocial but less ‘extreme’ biology of the Cryptomys and Fukomys common mole-rats… or, at least, evolved from common-mole-rat-like mole-rats.

Is there a queen rat?

Colony Behavior Several dozen rats live together in colonies led by one dominant rat—the queen. As in some insect species, the queen is the only naked mole rat female to breed and bear young.

Are naked mole rats blind?

Because mole-rats are virtually blind, their sense of smell is also very important.

What animals eat naked mole rats?

Naked mole rats are primarily preyed upon by snakes—especially the Rufous beaked snake and Kenyan sand boa—as well as various raptors. They are at their most vulnerable when constructing mounds and ejecting soil to the surface.

Can a naked mole rat swim?

No sheath. With all these deviations, it’s no surprise that the naked mole rat’s sperm won’t be winning any races. Only between 1 and 15 percent of them can actually swim, and just 1 percent of these can swim quickly. The vast majority move at a slow crawl; they might even be the slowest sperm of any mammal.

Are there queen rats?

There can only be one (queen) So, yes: queen-bee-style, the most dominant mole rat ladies fight off competitors for the right to bear their colony’s young (while everyone else does the actual child-rearing) by, well, breeding as fast as possible.

What’s special about naked mole rat?

Longevity. The naked mole-rat is also of interest because it is extraordinarily long-lived for a rodent of its size (up to 32 years) and holds the record for the longest living rodent. Naked mole-rats are highly resistant to cancer and maintain healthy vascular function longer in their lifespan than shorter-living rats …

What’s so special about naked mole rats?

Naked mole rats are cold-blooded, which saves them the trouble (and energy) of thermoregulating. They chew like a beaver. A quarter of their muscle mass resides in their jaws, and their lips close behind their teeth, so they don’t get mouthfuls of soil while digging.
