![]() ![]() Snakes in the wild will try to find a safe den that will stay above freezing. If you have a captive snake, a sudden loss of appetite outside of winter can mean that your heat source isn’t working properly anymore. Generally, they will cease eating early enough that any food can pass fully through the digestive tract. Once the temperature drops, snakes lose their appetite. If a meal takes too long to digest, the food will rot in the snake’s stomach and can harm or kill the snake. This is because snakes rely on outside temperature to help them digest. When the snake senses the approach of winter, they will generally lose their appetite. Many captive snakes will still cease eating even if their temperatures stay the same. ![]() Snakes generally rely on temperature, hours of daylight, and their own internal clock to tell them when to brumate. Corn snakes need to brumate to breed, and many have noted that ball pythons will produce more eggs if they are cooled before the breeding season. Some species even require a drop in temperatures and daylight hours to increase reproductive success or breed at all. The only snakes that do not typically experience cooler temperatures are tropical snakes. Most snakes in temperate or subtropical climates will brumate if it is cold enough. Once spring arrives, Eastern garter snakes take the chance to breed while they are gathered together. Hundreds of snakes from single or multiple species will share a den site. They have been known to travel long distances to reach these dens. Species like black racers may share the den and even prey on baby rattlesnakes once the temperatures rise.Įastern garter snakes famously brumate in communal dens. Snakes like timber rattlesnakes will return to the den where they were born. Many snakes will select a den site and wait out the winter in it. Snakes also typically need less oxygen during brumation since all of their metabolic processes have slowed down. They may also come out to bask on warmer days. Snakes will wake up to drink during the winter. Snakes require access to hydration during brumation. Snakes do not sleep through the whole winter, they are just slow and sluggish. This prevents weight and muscle loss over the winter. Snakes use fat primarily for reproduction, while glycogen can keep muscles fueled while the snake fasts during winter.īrumation allows snakes to survive periods where they cannot digest a meal by slowing down their metabolism. Snakes prepare for brumation by building up glycogen. The name for overwintering behavior in snakes is brumation. Reptiles like snakes go through a similar process, but there are differences. ![]() The animal will then sleep until spring and warmer temperatures arrive.ĭuring hibernation, mammals will not move or even really awaken. In mammals, hibernation involves building up fat stores to last the winter. The metabolism of the snake will drop to allow them to survive long periods without food. In general, if a snake lives in a habitat that has a cold winter, it will engage in something similar to hibernation. This may lead you to wonder if snakes survive the winter by hibernating like some mammals. You may live in a place that sees snow in the winter but still has snakes that appear during the warmer seasons. This can include habitats where the temperatures drop during winter. They have a wide range of habitats ranging from forests and grasslands to deserts and rocky mountainsides. Snakes can be found on every continent except Antarctica. ![]()
