What kind of covering does a snake have

We don't see this from other animals, so why do snakes shed their skin whole? Put simply, snakes shed their skin because it doesn't fit anymore or because it's old or worn out.

When snakes grow, their skin does not, so they outgrow it. When this happens, they shed their outer layer of skin. Snakes can shed their skin as often as once a month, although it's usually only a handful of times a year at most, according to Animal Planet. The process of shedding skin is called ecdysis, and many factors can affect how and when snakes shed, including species, age, weather and temperature, nutritional health and the presence of bacteria or parasites.

Nonvenomous snakes, which range from harmless garter snakes to the not-so-harmless python , dispatch their victims by swallowing them alive or constricting them to death. Whether they kill by striking with venom or squeezing, nearly all snakes eat their food whole , in sometimes astoundingly large portions. Scales serve several purposes: They trap moisture in arid climates and reduce friction as the snake moves. There have been several species of snakes discovered that are mostly scaleless, but even those have scales on their bellies.

Snakes also have forked tongues, which they flick in different directions to smell their surroundings. That lets them know when danger—or food—is nearby. Snakes have several other ways to detect a snack. Openings called pit holes in front of their eyes sense the heat given off by warm-blooded prey. And bones in their lower jaws pick up vibrations from rodents and other scurrying animals.

When they do capture prey, snakes can eat animals up to three times bigger than their head is wide because their lower jaws unhinge from their upper jaws. About once a month snakes shed their skin, a process called ecdysis that makes room for growth and gets rid of parasites. They rub against a tree branch or other object, then slither out of their skin head first, leaving it discarded inside-out. Skin shedding in reptiles is different. Instead of an ongoing process, reptiles shed skin periodically.

Snakes are even more unique, because their skin usually comes off in one piece. If you've ever seen a snake skin , you know it looks like the snake just slithered right out of its skin , almost like taking off a sock! Scientists call this process ecdysis , although you may also sometimes hear the terms sloughing and molting. Snakes shed their skin to allow for further growth and to remove parasites that may have attached to their old skin.

As a snake grows, its skin becomes stretched. Unlike human skin , a snake 's skin doesn't grow as the animal grows. Eventually, a snake 's skin reaches a point where further growth is not possible. When that occurs, a new layer of skin grows underneath the current one. As soon as it is complete, the old skin peels away, leaving behind a snake -shaped shell along with any parasites that may have been attached.

To leave their old skin behind, snakes may go for a swim to allow water to loosen the old skin even further. When they're ready to shed the old layer, they create a rip in the old skin , usually in the mouth or nose area. They often do this by rubbing against a rough, hard object, such as a rock or a log.

Once the old skin layer has been breached , the snake inches its way through the old layer until it's completely removed. If you find a snake skin in the wild, you'll notice that it's usually inside out and in one piece. Snakes shed their skin quite often. The average snake will shed its skin two to four times per year.

This average varies with age and species, however. Young snakes that are actively growing may shed their skin every two weeks. Older snakes might only shed their skin twice each year. Did today's Wonder of the Day make your skin crawl? We hope not! Find a few friends or family members to help you check out the following activities:.

Thanks for asking, Collin! We ask that Wonderopolis be listed as the author. Since we do not list the publish date for our Wonders of the Day, you may put the date you accessed this page for information.

Accessed 18 Jan. Hi, rav! Thanks for the question! We recommend that you contact your local U. Fish and Wildlife Service. I own 3 Gartner snakes and one just molted out of its skin. Is it okay to pick it up? Is it sanitary? How does it feel, what's the texture? Is it silky and soft or is it crunchy and hard? Excellent questions, Phoenix!

Thanks, Coleman! Do you have a pet snake, or have you ever seen a snake shed its skin before? Great question, Susie! Snakes do shed their skin in one piece. When snakes are ready to shed their skin, they create a rip in the old skin , usually in the mouth or nose area, and they can do this by rubbing against a rough, hard object, such as a rock or a log. After that, the snake inches its way through the old layer until it's completely removed. What up, Brixley?

We do not have a Wonder on scorpions yet but you should submit it to our Wonder Bank. Thanks for the great idea! Sorry Chloe's dad but no snake!

That's awesome, Sunny! We get a little creeped out sometimes with all the pictures, but they certainly are fascinating creatures.

We're so glad you visited Wonderopolis, nacole! We hope you learned some new things from this Wonder! Hi, Jethro! We hope this Wonder was helpful and informational! We encourage you to keep researching your question at the library and online! Great question, Ahriana! You can always keep researching at the library and online!

Thanks for joining the discussion, yahyalazim! We're glad you liked this video! Thanks for sharing what you learned, jameson!

A snake continues to grow its entire life, but its outer skin does not, so the snake needs to shed, or molt, its external skin from time to time.

About two weeks before it is ready to shed, the snake stops eating and its skin turns dull as a fluid begins to separate the old skin from the new. To cast off the old skin, the snake may rub its head against a rough surface to help turn the skin inside out, much like you might pull off your socks!

A baby snake sheds soon after hatching or birth to help evade predators by leaving its scent and skin behind as it wiggles away. It grows quickly at first and sheds several times in the first year. As the snake gets older, it molts less often, perhaps just two to four times per year. The warm months of summer are sometimes called snake season—not because there are more snakes, but because more people go outdoors in the summertime, often into snake territory.

Just let it be. Chances are good that it will quickly crawl away, and you can both go about your business! Yet when you consider how quickly rodents and rabbits reproduce, we owe a big thanks to snakes for helping control these populations. Scientists have been researching ways snake venom can be used in human medicine. It is estimated that 30 percent of South American snakes and lizards are endemic to the Brazilian Atlantic Forest.

The golden lancehead is at critical risk due to collection of snakes for the illegal pet trade and natural disasters such as wildfire.

In addition, six first-generation zoo-bred snakes may one day form the nucleus of a third assurance colony at the San Diego Zoo.

A better understanding of population dynamics and factors affecting these snakes will help us establish more direct actions for golden lancehead conservation. Diverse in size and color, with an important role in the web of life, snakes should be appreciated for their beauty and respected as fellow dwellers on this planet. Please leave them be. By supporting San Diego Zoo Wildlife Alliance, you are our ally in saving and protecting wildlife worldwide.

Reproduction: Some species lay eggs oviparous , some bear live young viviparous , and some develop eggs within the female that hatch at birth ovoviviparous. Snakes grow their entire lives!
