She found that, at rest, the heart of the naked mole rat beats very slowly (250 beats per minute). The rodent should have a heart rate twice as high for its body size.

What is the heart rate of a mole?
The heart rate of the mole rat in thermoneutrality and normoxia is 142 ± SD 15 min⁻¹. It is less than 0.5 the heart rate of the white rat and about 0.4 the expected value for a normal mammal of its size.
How long can a mole hold its breath?
But naked mole-rats? Although they lose consciousness after 30 seconds, and their heart rates crash after two minutes, and they stop breathing entirely after seven minutes, they can survive for a ridiculous 18 minutes. “We think they go into a state of suspended animation,” Park says.
Why can mole rats survive without oxygen?
They have high levels of a transporter molecule called GLUT5 as well as an enzyme called KHK. In combination, the transporter and the enzyme allow the rats to use fructose, instead of glucose, for energy — a molecular process that is anaerobic, meaning it doesn't require oxygen.
How does a naked mole rat survive?
Mice without oxygen die after around 20 seconds. Previous studies have shown that naked mole rats conserve energy by slowing their movements, reducing their breathing rate, and dramatically slowing their pulse. They're the only mammals known to survive suffocation through this type of suspended animation.
What is the heart rate of the naked mole rat?
She found that, at rest, the heart of the naked mole rat beats very slowly (250 beats per minute). The rodent should have a heart rate twice as high for its body size.
Can moles be brown?
The typical mole is a brown spot. But moles come in different colors, shapes and sizes: Color and texture. Moles can be brown, tan, black, red, blue or pink.
Why do moles make molehills?
The molehills are just the spoil from digging tunnels; it is easier for moles to get rid of this spoil on the surface when the tunnels are shallow. As the ground dries, insects follow the moisture level down, and the moles follow.
Do moles have to come up for air?
Once a mole has excavated its network it has no need to extend or leave its home, provided there is a frequent supply of prey falling in – mainly earthworms, millipedes, centipedes and beetles.
Can naked mole rats survive without oxygen?
Naked Mole-Rats Can Survive for 18 Minutes Without Oxygen.
How long can naked mole rats go without air?
Scientists can now add another oddity to the naked mole rats' repertoire: they can go for hours without much oxygen. Naked mole rats can survive for six hours in extremely low oxygen environments, according to new research from labs in Chicago and Berlin, and for 18 minutes with no oxygen at all.
Why do naked mole rats use fructose?
The naked mole-rat has evolved the ability to use fructose to fuel vital organs such as the heart and brain under near-anaerobic conditions.
How long can the brain stay without oxygen?
According to the University of California, Santa Barbara's UCSB ScienceLine website, the brain can withstand three to six minutes without oxygen before brain damage occurs.
Do naked mole-rats have a queen?
Only one female in a colony of naked mole-rats produces offspring; this female is called the queen. She mates with only a few of the colony's males, and these relationships can remain stable for many years.
Are moles blind?
Moles are often thought to be blind when in fact they can see; they are, though, colorblind and have poor vision only adapted to recognize light. To find food and to navigate the dark underground, moles rely on their keen sense of smell and touch. ... Moles are small, burrowing mammals who live underground.
Can you keep naked mole-rats as pets?
Naked mole rats should not be kept as pets. They require a very specific diet and habitat. It would be incredibly difficult to care for them properly.
