This selection includes the 10 Animals That Can Survive Without Food. It seems that following without food is not so uncommon in nature. People eat regularly because they can and do have what to eat, but not all animals have food so easily. Some animals have inherited impressive features, and can survive long periods without the need to feed themselves.
The camel has a great ability to survive for long periods without food or water. In fact, they can live longer without water than without food. Part of the reason for this is the large amount of water they store in their hunchback.
No, it’s not all water, it’s adipose tissue. Where there is no food or water around the fat in the hump, it is metabolized and water is released as a part of this process. In fact, the amount of water released into the body is about the same as the amount of fat burned.
The fat is stored in a hump rather than spread evenly throughout the body, so the fat does not act as insulation, and keeps the body warm. While metabolizing, fat releases water and energy, there are still nutrients that the camel needs to survive.
The longest recorded case of human survival without food was from Bhagat Singh. In 1929, Singh led a hunger strike while he was being held for murder, demanding better conditions for Indian prisoners. His hunger strike lasted for 116 days, and he fed again only after receiving government concessions and appeals from his father.
Unlike most other animals in this selection, the dog is a mammal and has to maintain a certain body temperature to stay alive. The dog’s metabolism acts to maintain body temperature at times when the outside environment is colder than the minimum temperature the dog needs.
And therefore, need to eat to fuel your metabolism. However, there are cases of dogs living for incredible long periods without eating food. There are numerous cases where dogs have been known to survive for weeks and a case where a dog followed for almost 3 months without food.
The male emperor penguin receives the dubious honor of remaining with the couple’s only egg for the winter, while the female follows and finds some food for herself.
During this incubation period, the male who harbors the egg with his feet, this will not eat or drink. But that’s not all. When the female returns, the male can follow to obtain some food, often even weak, he has to walk up to 120 km to reach the sea.
Like other reptiles, snakes can not regulate their own body temperature. When they become cold, body temperature lowers and when it is cold enough, they go into a state of numbness.
Unlike hibernation where the animal actually goes to sleep, the snakes remain awake. The metabolic rate of snakes in this dormant state is so low that they are able to live for long periods by surviving on the energy stored in their bodies.
Frogs have the ability to “breathe” through their skins and they can survive under conditions that allow this as the only way to get oxygen in your body. Frogs can hibernate, or enter a dormant state that uses so little energy, that they can remain this way for months.In fact, some species of frog are allowed to freeze. Their internal organs are protected by high levels of glucose and when the temperature increases their heart starts again and they follow as if nothing had happened.
Spiders have an exceptionally low metabolism compared to other creatures. The Rabbit Hutch spider, Steatoda Bipunctata, found throughout North America and Europe, was held in captivity for 18 months without water or food and showed no signs of distress.
Crocodiles are ancient reptiles that regularly follow for long periods without food. Because crocodiles rely solely on outside temperature to regulate their internal body temperature, except for gasp or movement between the sun and shade, they do not need food to maintain a metabolism that maintains body temperature.
Crocodiles are very efficient at storing energy in their bodies and are able to eat large meals. This and their staying ability without reduced movement for long periods mean that they can go without food for up to 3 years.
Lungfishs are freshwater fish . Just as they are able to survive incredibly long periods without food, they are creatures with a long life . An aquarium in Chicago has had a Lungfish in captivity for the last 81 years. Generally, in the dry season, they dig a hole up to 1 meter and live there for 6 months to 4 years. Although it spends little energy, its metabolism continues to consume the energies of muscle proteins . When the rains return, they are weak and thin. In less than 1 month they return to their previous state after eating.
They are predators of small crabs and snails and are extremely good at storing food in the body like lipids and glycogen. When there is not much food around, they reduce the metabolic rate and become inactive by living off the nutrient reserves. Documented checks have shown that these creatures can live for up to 10 years without food.
