![]() In fact, with the warmer weather we experienced and the ginormous amount of rainfall from the hurricanes, they are just as active as ever. With cooler weather finally upon us, you may think that venomous copperhead snakes would be well on its way to hibernation. Because the coldest temperature any snake can thrive in is around 65° Fahrenheit ( 18° Celsius), snakes normally live in the warmer temperate or tropical zones. Snakes usually stay out of cold climates. What is the coldest temperature a snake can withstand? In warmer southern states, snakes often don’t go into hibernation, but brumation. Generally, rattlesnakes emerge from hibernation in March or April, or when the average daytime temperatures reach and remain about 60 degrees Fahrenheit and higher. At what temperature do snakes become inactive? Snakes turn in for the evening, sleeping at night. Snakes are most active in the early mornings on spring and summer days when the sun is warming the earth. On warm days, snakes in brumation sometimes come out of their dens to bask in the sunshine. Keepers of brumating species should always be aware of the signs and know how to properly facilitate this process in captivity.Snake activity picks up as temperatures fall in late summer and early autumn before they go into hibernation, which can be as early as September or as late as December. Adult bearded dragons and many species of tortoise, for example, often brumate in captivity. While it’s possible some captive snake species may attempt brumation, it’s far less common in captive snakes than it is in other commonly kept reptile species. Keepers can facilitate brumation by lowering the temperature in the snake’s enclosure, but this should always be done with caution and knowledge of proper brumation care requirements. Brumation in captivityĭespite captive individuals experiencing a mostly consistent environment, their biological functions can often kick in telling them to begin brumation despite not seeing a drop in temperature. Commonly kept species like garter snakes ( Thamnophis), and corn snakes ( Pantherophis guttatus) are known to brumate both in the wild and occasionally in captivity too. Lizard species like the central bearded dragon ( Pogona vitticeps) will often bury themselves in wet soil to reduce the distance needed to travel for water.Īll North American snake species brumate due to the region’s colder climate. While hibernating mammals will stay in this slumber for the entirety of the hibernation process, brumating reptiles and amphibians will sometimes slink off for a drink of water during their comparatively lighter nap.īrumating species are also able to tolerate significantly lower oxygen levels than hibernating mammals. While brumation could be considered the ectotherm’s hibernation, the processes do differ slightly based on the biology of the different groups.īefore going into hibernation, mammals will build hefty fat reserves which their body uses slowly throughout the season to sustain their deep sleep. This means they’re able to allow their body temperature to drop dramatically during brumation, with some species of alligator choosing to spend part of their winter submerged in frozen water. Reptiles and amphibians are poikilothermic, meaning they can withstand drastic changes in body temperature without suffering negative impacts on their organ function.
