Why Can Spiders Live So Long Without Food?

It particularly applies to spiders because they have a metabolism roughly 50% of the speed of other animals.

Spiders are also carnivorous and acquire a lot of energy than a vegetarian will have from their meal.

Then you have to examine most spiders’ everyday activities. Many of them are stationary predators that hardly move all day long. This means that relatively little energy is used.

Many spiders make webs, a procedure in which a great deal of energy is used, but many spiders only feed and utilize this protein to create a new one. 

So, this mixture of extremely slow metabolism, quiet, basic lifestyle, and low-efficiency hunting policies enables spiders to exist without food for quite a long period.

Food tarantulas: amazing outliers

Although tiny, ordinary house spiders are capable of living without food for around 2-4 months, tarantulas are considerably longer able to live. In reality, the homeowners of tarantula often claim that for six months to two years their tarantulas haven’t eaten! It’s also not due to a food shortage – they simply don’t eat.

It’s hard to tell why tarantulas have this odd behavior. It’s because they’re going through a long molt occasionally, and because they’re “fearful” of others. But it’s only what they do much of the time. In fact, several kinds of tarantulas, including Grammostola Rosea, are renowned for unusually extended hunger strikes.


With most spider species, 4 to 8 weeks is the maximum amount of time they can go without food or water. However, some spiders can stay for years without having any food, this is very rare. All spiders are capable of storing water in them, therefore, they will be able to store water in their possession when they are fasting or when food is scarce. 

They will still survive for several weeks without any food even after the food reserves are gone. This may relate to the fasting spiders do often throughout their lives. When you’ve been feeding your spiders for weeks and want to attempt feeding them, ensure that the prey you are supplying is alive and lower than normal. 

Therefore, if you choose to get a spider as your pet, you will need to understand very well the kinds of foods that they eat and their requirements in terms of water intake for survival. Usually, the amount of food they require is determined by the size, species, and type of food given to them.
