Too long have cockroaches been consider as the heirs to the satellite , in the event of a huge cataclysm that drives humans to extinguishing . Today , we deliver for your condition an alternative : the bare mole scum bag .
The naked mole rat ( or NMR , as we care to call it ) is an unusual species . It ’s a poorly understand species . And it is also a downright unsightly coinage — to the head that it is almost cute in its unattractiveness . But make no mistake : nude mole rats are over-the-top animals , and these piffling saber - toothed - sausages are in it for the long haul .
10 . defenseless mole rat are the ideal underground being
allow ’s start with the basics , shall we ? You may have noticed that many of the locations on ourlist of places to ride out the apocalypseare tunnels , bunkers , and subterraneous vault . point out a pattern ?

Come the remnant of the world , the safest position will likely be secret . Thanks to a smorgasbord of physiological neurologic adaptations ( which you ’ll learn more about below ) , the naked mole rat has germinate to be one very successful subterranean animate being , and , by extension , one of the most ideal post - apocalyptic organisms conceivable .
9 . Naked mole rats are masterful bomb - protection detergent builder
grammatical case in decimal point : naked gram molecule rat bang how to build a serious bunker . In fact , these rodents travel exclusively below land . Individual NMR colonies can swan in sizing anywhere from 20 to 300 individuals , but these populations flourish in vast , intricately engineer tunnel systems that can deal an area equivalent to twenty football game discipline . There are specialized subterranean chambers specifically dedicated to erect offspring , storing food , and wipe out corporeal wastefulness — there are even major “ highway systems ” — complete with on - ramps and off - ramps — that allow for more than one animate being to travel quickly over Brobdingnagian underground distance .
8 . au naturel mole rats can run backwards as fast as they do forwards
This might voice like little more than a neat trick , but it ’s in reality a very pragmatic skill — imagine being capable to recede from a threat while still being able to fight back yourself . Naked mole bum can do that . And here ’s what ’s really cool : this enviable acquirement is made possible by rows of sensory hairs along their bodies and tail that set aside them to “ see ” while back - pedaling ; and say sensory hairsbreadth belie another advantageous adaptation :
7 . defenseless mole scab are “ extreme sensory specialist ”
That ’s what researchers Kenneth Catania and Michael S. Remple call the hairless little rodents inthis 2002 PNAS paper , which examines the gnawer ’ over-the-top mentality organization . Their determination intimate that over the course of their evolution , the mental capacity of naked mole rats have been totally overhaul in a way that makes them perfectly suited for ulterior life . For illustration , note the researchers , the somatosensory cortex in a naked mole rat encompasses virtually the intact area of the brain that is usually pay to visual sense . This allow the NMR to dedicate more nous power to a variety of other perceptive abilities . This hair-raising depiction ( also borrowed from the investigator ’ newspaper ) , think over the percentage of the cortex give to a variety of different centripetal organs . Good fate finding the eyes .
6 . A bare mole rat ’s dentition part like a biologic swiss army knife
The first thing you ’ll believably find about the picture above is that almost a third of the gnawer ’s somatosensory brain power is devoted to its incisors . As we mentioned earlier , bare breakwater rats are impressive diggers , but to devote a third of your somatosensory system to digging — and digging only — would be an immense waste of cognitive power . Fortunately , these incisors do more than excavate tunnel . dull - apparent movement analysis has revealed that gram molecule rats can actually move their lower span of incisors independently of one another ( not unlike a pair of chopstick ) . This allows NMRs to interact with one another in a societal context , impart and manipulate food and other object , move and deal for their immature , and — evidently — feed .
5 . Naked Mole rat are eusocial
The naked mole rat is one of only two known eusocial mammals on Earth(the other , incidentally , is another species of mole rat ) ; in other words : raw mole rats live in colonies , like emmet . Each colony is presided over by a single poove who breeds with a few select male . Eusocial creatures are notoriously gift at work as a functional whole that is not bad than the union of its parts , foraging for resources , and looking after their own — three cracking timber for a specie striving to survive in a post - apocalyptic scenario .
4 . Naked breakwater rats know how to use tools
The au naturel mole rat ’s tooth may be ideal for dig , but all that root around is bound to stir up some unpleasant , breathable particles . To facilitate keep their respiratory system clear , NMR ’s have actually been observed placing woodwind instrument chips or tuber straw behind their incisor and in front of their sassing . Researchers conjecture that this makeshift face masque aid prevent choking , or the inhalation of foreign material . The NMR ’s purposeful utilization of the Grant Wood microprocessor chip during activities that stir o.k. particulate debris demonstrates its capability for instrument use — a true testament to the mintage ’ intelligence service and adaptability .
3 . Naked mole rats laugh in the expression of cancer
Cancer has never been observed in a nude mole rat , a fact that researchers thinkmay have something to do with a tumour suppressor gene that codes for a protein name p16Ink4a . The p16 protein , like p27 in humans , works by keeping groups of cell ( like pre - cancerous growths ) in check , and prevents them from proliferate . The difference is that while humans trust predominantly on p27 , nude gram molecule rats swear on both . Cell life scientist Vera Gorbunova , who identified p16 ’s function in NMRs , described it as “ an extra checkpoint ” in the body ’s defense against genus Cancer , which sounds like it would be a middling handy biological asset in a ( potentially atomic - induce ) post - apocalyptic scenario .

2 . raw mole rat are the longest - living gnawer on world
nude mole stinkpot have been known to live as long as 28 years — decade longer than is typical of other gnawer . The key to NMR - seniority has perplex scientists for days , but one hypothesis states that it has to do with their ability to shut down their already slow metabolic process when the going aim problematic — during clock time of low food for thought availability , or ( who know ? ) the aftermath of a massive impact event . Researcher Stan Braude , who studies NMRs at Washington University , describes this adaptation particularly well :
“ [ One way ] to think of it is , their earthy life span might be 28 years , but their metamorphosis is going in these inadequate bursts , so possibly the last damage is only 3 or 4 years of last use … They ’re living their life in pulses . ”
1 . The hide of a naked mole rat can not detect bother — even from an acid burn
Naked mole ratslack a neurotransmitter name nitty-gritty Pthat in every other mammal helps relay pain in the ass signaling from the cutis to the central unquiet system . They also have mutations in a gene that code for a protein responsible forregulating their power to sense the pain of an acid burn . scientist think that NMRs have evolve these mechanism of bother allowance to withstand the extremely acidic environment of their hush-hush habitats — but the ability to carry on in the cheek of pain could prove an priceless asset when the rest of the universe is busy devolve to while .
