How Snakes Survive Starvation

Serpents Stay Alert And Strong Without Food.

Some snakes are known to be able to go without food for periods of nearly two years. Until recently, the mechanism behind the unique ability was unknown, but new research has revealed some previously unknown to the Serpentine tricks. These can be a key adaptation that was a very specialized group alive even before the days of Tyrannosaurus Rex, biologists say.

Biologists have long argued that there are two main tactics used by animals to weather a period of famine. Body temperature can be reduced, as is the case of penguins go through apathy to reduce their calorie intake during the winter. Hibernating animals such as hedgehogs use another method of food supply and reduced levels of activity. Some species like polar bears, both.

Snakes, apparently in a completely different strategy in place - can save energy consumption without lowering the temperature, while remaining fully alert. As a bonus, may also be hungry for more, starts to "eat" the inside of the body.
