Snakes in popular culture are often treated as voracious and alien creatures, and at that place's some degree of truth to that. The ability for snakes to unhinge their jaws and swallow prey of seemingly impossible sizes whole is incredible, and that's doubly true when speaking of an enormous ophidian like an anaconda. But what may seem horrifying to u.s.a. is a sign of evolutionary success.
Natural selection caused the ophidian to lose the 4 legs its ancestors accept, but serpent species have now come to represent a 3rd of the total number of reptile species. On the surface, the snake takes several circuitous biological processes and reduces them to their most basic parts for the sake of all-around its archaic body shape. Simply that'southward also forced snakes to prefer some truly creative — and oftentimes ghastly — characteristics to assist them perform tasks that creatures like humans and chimps take for granted.
Due to some of these unique alterations, snakes tin can go a long fourth dimension without needing a meal. Merely the whys and the hows are the of import part of the answer. This is how some snakes accept developed the ability to go for long periods without eating and how circumstances led to them becoming this way.
How Snakes Swallow Their Prey
The open and hissing jaw of a snake might be terrifying upward close, but it's also a reminder that nosotros're lucky to exist able to chew. All snakes are ambush predators, but they've developed iii primary methods for consuming prey, each of varying effectiveness depending on the size, nature, and environment of a species.

Venom is maybe the most effective. The needle-similar fangs of snakes may not be neat for ripping and trigger-happy at an animal'due south torso, merely they're finer built similar hypodermic needles. In one case the venom does information technology work — by either killing or paralyzing prey — the ophidian can become to work swallowing information technology. In some cases — such as with pit vipers like rattlesnakes — the venom tin can even begin the process of liquefying a casualty animal's insides to make them easier to assimilate. Merely only about one in five snake species is venomous.
Constrictor species are more common, as they utilize diverse methods of crushing their prey to incapacitate them before swallowing them. Others — like the garter snake — are unproblematic constructive predators that can accomplish out and swallow prey whole. For constrictors and venomous snakes, the real chore comes from actually swallowing their prey. Unable to rip or cut the mankind, these snakes have to open their jaws as wide every bit they tin and slowly wiggle their lower jaws underneath the casualty animal like lining up a forklift. A serpent's upper and lower jaw don't detach from 1 another, but it tin open up to 4 times the width of a snake's trunk. Their skin is similarly designed for flexibility, and to grade effectually the nutrient item.
How Snakes Expend Their Energy
Wrapping your head around how these legless reptiles can go so long without food requires an understanding of how and why different types of animals require dramatically different amounts of free energy. While the organisms that cover this planet take incredibly diverse forms, the process of natural option that underlies everything is driven past the uncomplicated arithmetics of energy expended and energy consumed. As warm-blooded animals, humans and all other mammals can maintain their body temperature internally. While this allows mammals to be more agile than their reptilian counterparts, this active metabolism is likewise plush in terms of free energy. The cheetah is the world's fastest land mammal, but properly maintaining that body means eating over six pounds of meat a day.
Reptiles can beget to be more than energy efficient because they use an external ability source. Natural heat and light become them active and moving, and snakes can work at optimum effectiveness between 80 and xc degrees Fahrenheit. Their lower metabolic rate means that they accept to consume less nutrient in the kickoff identify, and the average reptile requires only 20 to 25% of the nutrient intake of a mammal. It'southward an constructive style to succeed considering it allows them to succeed even when opportunities might non be sustainable for more than lethal just besides more than energy-dependent mammal predators. It as well allows them to finer alive through cold conditions without having to blot the cost of maintaining their trunk heat or developing specialized behavior like hibernation.
How Snakes Digest Their Prey
Beingness able to disable their prey with a single venomous bite and then swallow them whole frequently allows these ambush predators to both hunt and feed with very footling free energy expenditure — only digesting their repast is a very costly procedure. The Burmese python is an extreme but representative example. Once a fresh meal is carried into the esophagus and begins the chemical process of beingness broken downwards inside the serpent'due south tummy, this serpent's body begins to mutate wildly. Their metabolism will accelerate up to 44 times its original rate, and their organs can grow up to 2 times in size to maximize the efficiency of the digestion process. This isn't the norm, simply information technology'southward impressive when y'all consider that most snake species will typically eat a quarter of their trunk weight in a single sitting. Pythons are peculiarly voracious eaters, and some pythons take been known to eat up to 95% of their body weight.
Human beings may need three square meals a day, but a snake can simply gorge once then take a long nap while digesting it. The actual digestion process tin vary depending on the size of the ophidian, the surrounding temperature, the size of the repast, or several other conditions. Shorter meals can have three days, merely information technology could take a massive snake, like an anaconda, weeks to fully assimilate a larger meal such as a deer.
In that location are dangers involved with longer and more than hard digestion processes. Larger game is more likely to have horns, fangs, or claws that can pierce an internal organ and kill the snake. They need to be exposed to heat to properly digest, but they're also vulnerable targets every bit long as they're engorged with their meal. And while the digestive acids beingness used are potent, a ophidian's organs are in a race against their casualty. If it tin can't deliquesce the prey faster than the corpse can decompose, the snake's repast could poison it, grow inside its tummy, or trigger the explosion of gases. It tin can be a costly risk, simply a big meal dramatically increases the amount of time that a snake can go without eating.
The Average Snake's Dietary Schedule
In terms of how often and how much food the average snake needs, it can vary tremendously between dissimilar species. Researchers accept identified both frequent and infrequent feeders, with the latter exhibiting the behavior of ball pythons demonstrated for growing their organs to assist with digestion. Infant snakes and frequent feeders might swallow well-nigh twice a week, while exceptional feeders may comfortably go without eating for a couple of weeks at a time. In farthermost cases, it might be weeks before the concluding repast is even digested.
As reptiles, snakes are too capable of a land called brumation which allows them to sink into a deep torpor during colder months. It tin be a critical method for survival when prey tin can be scarce and hard to track — and with a lack of sunlight and heat, virtually snakes are ill-equipped to hunt anyway. Corn snakes are known to go 2 to three months without food during brumation, simply many species volition accept periodic breaks during longer brumation periods to hunt for new food.
How Long Snakes Can Go Without Food
A baby serpent will begin to seriously starve later roughly a week without food — and one time that baby grows into an adult, members of most snake species tin comfortably get by for at least 2 to iii weeks. Simply the fourth dimension it takes for a ophidian to starve can depend significantly on the species. Smaller snakes tend to feed more often than larger ones, simply species similar the ball python can go for as long every bit two years without needing a meal. Without an internal metabolism to manage, the energy cost of doing nil is a lot lower than it would be for an equivalent mammal.
That said, science is just first to uncover the total survival capabilities of snakes. A study that looked at the tactics snakes apply when they might starve took diverse snake species and observed their behaviors when they were fed nothing for six months. In addition to their naturally low free energy needs, iii split up serpent species demonstrated the capacity to further lower their metabolism past as much equally an additional lxx%. Information technology'southward a fascinating but still uncertain look into how these creatures operate and how they might conceivably be able to survive without nutrient for even longer periods than we recollect possible.
