Which animal does the longest without food?

It is impossible to name the animal that goes without food the longest, since many species are either not discovered or not studied. But according to the data that is now there, one can call an animal that can do without food for the longest time among all the known ones. These are proteas – amphibians. Scientists have found that they can go without food for up to 10 years. Of course, they eat constantly and regularly, and in the absence of food, they fall into suspended animation to save energy, since any organism needs either a source of energy, or minimally use the body’s energy supply.
