Some animals demand to swallow multiple times a day to get the free energy required to survive. For example, an elephant tin consume 375 pounds of vegetation every day. However, other animals have adjusted to go long periods without nutrient. They attain this feat in various ways, from reducing their energy requirements to digesting their own body parts.

Reptiles

A variety of snakes, including vipers and constrictors, tin survive for weeks, sometimes months, without eating. Because snakes are carnivores and hunt live prey, they cannot snack or slake their hunger pains past eating vegetation. Instead, they slow their metabolic rate by up to 70 percent when necessary to survive. Despite this huge reduction in metabolic activeness, the snake will go on to grow. When the serpent is able to find prey, he will gorge, potentially taking days to digest what he caught. Crocodiles are capable of going for more than a year without eating.

Insects and Arachnids

Cockroaches can survive without their head. A headless roach is capable of living for weeks. It is not the loss of its head that kills the roach, simply the fact that he is unable to eat. With or without his head, the roach cannot go for more than than a few weeks without eating, despite existence common cold-blooded -- a mutual trait amongst the nigh impressive food abstainers. Tarantulas, also, can final for more than than a month without eating. Provided they are healthy, one meal can sustain a tarantula for several weeks without showing any sick effects.

Fish

While humans, dogs, elephants and a diversity of other warm-blooded animals consume daily, other animals accept adapted a famine and feast arroyo to nutrient. Neat white sharks tin can get for weeks without eating a single thing. The longer ane of these apex predators goes without food, the more opportunistic their hunting strategies become. The record holder for the longest fast, though, is the lungfish. The lungfish may hibernate for upwardly to iv years. During this period, he will begin to digest his own muscle tissues. This process, a blazon of auto-cannibalism, is called autophagy.

Winter Fasting

The emperor penguin is one of the few warm-blooded animals to go for weeks without eating. Due to the harsh winters they face on the Antarctic water ice, they have adapted to survive without food for up to two months while traveling to open water or broken water ice in which to hunt. However, different crocodiles and snakes, they practice not recoup by slowing down their metabolism. Instead, they survive on the fatty reserves built up during the final period of feeding. Hibernating mammals, such every bit bears and hedgehogs, besides build upwards deposits of fat to meet them through months of wintertime slumber.
