Photo be @Robert Clark | The #NakedMolerat is an extraordinary mammal, they are coldblooded, No other known #mammal is. They live in an underground tunnel complexes in colonies of hundreds led by a queen, they live in hives, much like bees. For several years scientists thought they didn't get cancer.
And now it seems that they can survive for 18 minutes with no oxygen. No oxygen. Generally, they can run their cells on glucose, the usual way of mice, humans and all other mammals. That process requires oxygen, which comes from breathing.
But mole rats can switch to a different kind of biochemical process that uses fructose, the sugar in fruit and high fructose corn syrup which needs almost no oxygen. The mole rat falls a suspended animation, with a much lower heart rate and breathing. Other mammals, like people and mice, can metabolize fructose without oxygen, only in a very limited way. Mole rats evolved this ability because the tunnels they live in can be low in oxygen.
