As warm blooded animals, we need to provide energy for our body by eating every day. We need energy to move the muscles, activate the nervous system and keep the senses sharp. If we don't eat enough food, we may get angry, dizzy, dehydrated and even sent to the emergency room.
Eating every day is a necessary condition for human survival. If the human body doesn't eat, it will appear various kinds of debilitating phenomena in a few days. But this is a piece of cake for many creatures. The following 11 kinds of animals are just like this. It is too normal for them not to eat for a few days.
1. Cave newt
These creepy amphibians live in underwater caves in Italy and the Balkans. They are similar to salamanders, but they spend their entire lives underwater. In this environment, resources are very limited, so they can live without food for up to ten years.
2. Shark
Great white sharks can last several weeks without eating. But the most amazing thing is that the longer they don't eat a full meal, the better their hunting skills are.
3. Bear
It used to be a big rumor that bears hibernate in winter, but they do sleep longer in winter and can avoid wasting energy by halving their metabolism. They wake up at Christmas and new year and can last about 100 days without eating or drinking.
4. Penguins
There is no doubt that penguins live in the worst places on earth. Contrary to the general biological concept of "male outside, female inside", female penguins are responsible for hunting in sub zero temperature environment, while males are responsible for staying in the nest to incubate eggs. During the two to four months when the female penguins go out, the male penguins can only rely on their thick subcutaneous fat in order to stick to their posts.
5. Camel
The hump on the camel's back is not used to store water. I believe you heard that when you were a child. Actually, humps are the fat that provides energy for them. When they walk across the desert, they can last about 40 days without eating or drinking.
6. Frog
Because frogs rely on humid environments, their body structure has a function that can rely on water to replenish nutrients in response to drought. When the dry season comes, some species can go into dormancy for up to 16 months. Other species that live in cold places also go dormant to save energy.
7. Snake
Although these cold-blooded reptiles can't regulate their body temperature in cold weather, they can slow down their metabolism by 70%, allowing them to eat no food for up to a year.
8. Crocodile
Crocodiles can wait motionless for prey to conserve energy. They usually last several months without eating, and in extreme cases, for three years. That may be why they have become one of the oldest reptiles on earth.
Spiders 9
Because spiders need to wait quietly for their food to arrive, sometimes they have to wait a while before their next meal. Don't worry, their bodies can last months without eating. If it's a fat belly spider, it can last about a year without eating.
10. Galapagos tortoise
These turtles can live for a century. You may think that they must have been worrying about what to eat every day for a hundred years, but these reptiles can live without eating for up to a year under certain harsh conditions.
11. Mudskipper
Mudskippers, also known as lungfish, from Australia, Africa and South America, can hibernate for about four years in extremely harsh conditions. But what's interesting is that when they sleep, they digest their own muscle tissue, so they're strong enough to survive!
Nature is wonderful! This proves that human beings are not omnipotent, but all kinds of creatures that can't. All creatures have their own unique life style. These strong survival abilities are trained in harsh environment. It seems that we humans should also think about these animals to learn!
