How Long Do Snails Sleep – Snails are members of the Mollusc family.
More than a thousand different species of snail exist and these creatures can be found all across the globe, on land, in the sea and in freshwater environments.
It has been proven that snails sleep, but their sleeping habits are unusual compared to those of most larger and more developed animals.

- Do Snails Sleep?
•) Snail Feeding
Most people believe that snails feed exclusively on plants, but it is not the case.
Some species are omnivorous and some even carnivorous, as long as they can obtain the nutrients necessary to have a hard and healthy shell.
•) Snail Habitat
Snails inhabit places ranging from sunny urban gardens to remote mountainous regions with cold climates.
The snails can thrive successfully in many habitats with different temperatures and conditions.
•) Snail Anatomy
Tentacles, brain, and heart are just some of the body parts of snails, soft-bodied gastropod mollusks with an attractive and rigid outer shell made mostly of calcium carbonate and essential for their protection and survival.
•) Snail Reproduction
Snails are hermaphrodites, this is, they have the reproductive organs of both males and females so they can produce eggs and spermatozoa, allowing them to self-fertilize without a sexual partner.
However, they usually copulate with a partner in the traditional way.
•) Snail Lifecycle
The life cycle of a snail begins with a hatching egg, passing later through several stages of their life like sexual maturity, mating and dropping eggs to reproduce.
•) Snail Predators
Snails have a simple defense mechanism that keeps some insects away, but this is often not enough for stronger enemies such as centipedes, squirrels, salamanders, or rats.
Some snails attack other species also becoming predators.
•) Snail Evolution
There are still many questions about the evolutionary process of snails, but their ancestors lived about 550 million years ago, leading to a wide diversification of species that adapted to different terrestrial and aquatic habitats.
15 Interesting Facts about Snail
1. Some Snails Hibernate
Some species of snails hibernate during the colder months of the year.
They cover their bodies with a thin layer of mucus, which prevents them from drying out.
Sometimes snails also do a similar process in the summer, called estivation, to survive if it is a dry period.
These processes are probably one of the reasons they have survived for millions of years.
2. Snails Can Have a Long Life
The life expectancy of snails depends on their habitat and the species.
Some of them only live for about five years. However, others in captivity can live up to 25 years old.
3. There are Giant Snails
The biggest land snail recorded was 12 inches long and weighed near 2 pounds.
It was a Giant African Snail. Other species are tiny being only a few centimeters long when they are adults and just a couple of ounces in weight.
4. Snail Moving
When moving, snails leave behind a trail of mucus.
This mucus acts as a lubricant to reduce friction against the surface where they pass.
5. Snail Mucus
It is a myth that snail mucus can make humans ill.
Many people worry that the snails in their garden will ruin the foods grown there and make them unfit for consumption, but that is false.
6. Snails Live in Slow Motion
Garden snails (Helix apersa) reach a top speed of 50 yards per hour; this is about 0.5 inches per second.
While they don’t move fast, they do move at a very steady pace.
Snails are one of the slowest creatures on the Earth.
7. Snails are Hermaphrodites
Snails have the reproductive organs of both, males and females, which categorize them as hermaphrodites.
However, they usually do not create offspring on their own.
They mate with another snail, and then both lay eggs.
8. Snails Can See But Can’t Hear
Most land snails have two set of tentacles, the upper one carry the eyes, while the lower one has the olfactory organs.
However, they do not have ears or ear canal.
9. Snails are Nocturnal
Snails are nocturnal animals, which means most of their activities take place at night.
Snails don’t like the sunlight, which is why you find them out more on cloudy days.
If you keep them in an aquarium, make sure that there is not too much sunlight in the room, or the snails will stop eating and hide inside their shell.
10. Get your size
Snails length ranges from a few centimeters to 12 inches.
11. Snail Care
Snails will die if you put salt on them. Make sure they are not in contact with salt if you have one in captivity because their body can´t process it.
12. Very Hungry
The Giant African Land Snail is known to eat more than 500 different types of plants.
13. Small, Not Weak
Snails are strong and can lift up to 10 times their body weight in a vertical position.
14. Large Family
There are at least 200,000 species of molluscs out there including snails, although only 50,000 are classified.
15. Are Snails Born with Their Shells?
Yes, although the shell is transparent and soft to begin with. Snails need calcium to harden their shells and the first thing a newly hatched snail does is to eat the casing of its own egg to absorb calcium.
Some snails will also cannibalise the shells of their unhatched siblings.
Over the next three months, the shell gets thicker and acquires the full adult colouration.
Do Snails Sleep?
They might be among the slowest and most laid-back of creatures, but even snails need to nap on occasion, reports Physorg.com.
New research out of the University of Toronto has revealed the first evidence that simple organisms like gastropods need to sleep too — discovery that only deepens the mysteries behind why animals need to sleep at all.
The study began after researchers Richard Stephenson and Dr. Vern Lewis from the University of Toronto.
They noticed that pond snails were spending about 10 percent of the time attached to the side of their tank with their tentacles partly withdrawn, their shells hanging away from their bodies, and with their feet symmetrical and relaxed.
To determine if the snails were sleeping rather than simply resting, the researchers observed how quickly they responded to applied stimuli such as being tapped on the shell, being prodded by a metal rod or being introduced to food.
Sure enough, active snails responded twice as quickly to physical stimulation and seven times faster to appetite simulation than the snails that appeared to be resting.
Eight of the snails were monitored for a full 79 days so that researchers could look for patterns in their sleeping habits.
Perhaps unsurprisingly, gastropods have much different sleeping patterns than people do.
For instance, snails follow a two to three day sleeping period rather than a 24-hour cycle, with clusters of around seven bouts of sleeping over a 13-15 hour period followed by over 30 hours of uninterrupted activity.
They also don’t appear to need to make up for lost sleep.
Though the reasons behind sleep are still largely mysterious, many experts acknowledge that sleep is important for neurological health, particularly when it comes to organizing and processing memory.
The fact that organisms with simpler nervous systems require sleep demonstrates that sleep may play a far more primordial role in biological processes than originally anticipated.
In fact, snails aren’t the only simple animals that sleep.
Animals like fruit flies, crayfish and even nematode worms have been shown to fall asleep, too.
Does this research mean that snails also dream?
Though there’s no evidence of that yet, it certainly makes one wonder about what a snail might dream about.
Tasty sucrose? Sexy snail shell curves? Do their nightmares involve being covered in salt?
For now, questions like these will have to wait.
How Long Do Snails Sleep
Many People asking about how long do Snails sleep. The good news is University of Toronto make research about it. The result is that Snails have a very different sleep cycle from people.
Rather than being part of a 24-hour day, their sleep cycle lasted two to three days.
Over a period of 13 to 15 hours, snails sleep in around seven bouts.
This sleeping period is followed by roughly 30 hours of activity.
If they lose sleep during their normal sleeping period, they seemingly have no need to make up for it.
Hibernation and Estivation
In addition to their day-to-day sleeping habits, snails also go into a deep sleep to avoid adverse weather conditions and periods when food is scarce.
In colder climates they hibernate during the winter months, and in hotter climates they estivate during the summer months.
When they go into hibernation or estivation, they seal themselves safely inside their shells with a layer of mucus that forms a hard cover over the opening.
How Long do Snails Sleep (Hibernation)
How long do Snails sleep?
Snail can sleep for 3 years.
The reason snails sleep are they alike many other animals hibernate.
Hibernation means that snails sleep when weather becomes excessively cold; it is a necessary for the survival of snails.
It is also been known some species of desert snails can do this for years before actually dying.Snails common diet are plants and other vegetation. Snails will bury themselves in the ground and close their shells off with their own slime.
You can find them eating live plants, dying plants, rotting plants, fruits, and algae. A snail has a radula located inside its mouth to assist in the grinding of its food.
Snail also be found eating the chalk off rock for provide the protein which needed for their shells.
Here’s some features about snails that how they manage to gather up all the moisture they need to survive:
The opening of the snail shell is covered with a slimy gel that prevents much air passage.
Snails are mostly nocturnal, so that the light of day not burn them out as badly.
Because they are hermaphrodites, they don’t need to worry about finding a mate in the dry air.
A snails habitat usually consists of on land or in water depending on the type of snail. Snails are not usually in need of perfect environments because snails carry their homes and place of safety on their backs.
Desert snails can sense when the air is particularly dry, and will burrow underground in order to retain moisture.
Where, they can hibernate up to 3 years, waiting for the temperature to become more suitable for them.
The average age of snail is 15 years.
How Can Snails Sleep for 3 Years?
Most snails cannot last that long without eating and being active. Some only live for a year anyway.
The few that can last more than a year without any activity tend to be long-lived species living in arid climates.
It is normal for them to “aestivate” in the hot, dry summers, effectively going into a state of suspended animation until it rains.
In real deserts the are a few that can survive in this state for several years.
The authenticated record is 6 years for a species from Baja California in Mexico, and there are others that have been clocked at 5 years.
Ultimately, the problem is loss of water. These snails are very good at preventing evaporation.
Apart from thick shells, they have an “epiphragm” or dry mucus sheet over the mouth of the shell, and the exposed part of the body within has mechanisms to slow the movement of water from the body to the surface.
There is one snail from Israel that can live for up to 19 years, but it is actually active for less than 5% of that time.
How to Know If Your Water Snail Is Dead or Sleep
Freshwater snails can appear dead in aquariums, but they often just remain inactive for many days.
Sometimes the snails float to the surface of the water due to the air in their lungs. If you suspect that the snail has died, you need to remove it from the water carefully to inspect it.
Leaving a dead snail in an aquarium can result in the spread of disease. Before you discard the snail, inspect it carefully to ensure that it is actually dead and not inactive.
Remove the snail from the water. Locate the opening near the body of the shell.
Smell the shell carefully. If the shell smells rotten or foul, the snail has died.
Examine the water snail shell carefully.
If the body of the snail is no longer inside the shell or if the snail hangs out of the shell and does not move, then the snail may have died.
Locate the trapdoor on the snail’s body. The opening will remain shut when the snail remains alive, but it will remain open when the snail dies.
Hold the snail shell in front of a light source such as a flashlight. Look at the heartbeat to determine if the snail remains alive.
You can only see the heartbeat in young and thin-shelled snails.
How to Know If a Mystery Snail Is Dead or Sleep
Mystery snails are more commonly known as apple snails and are aquatic pets found in freshwater aquariums.
They are generally hardy snails that can often survive in poor quality environments, but are prone to sudden death from disease or old age like any other pet.
Identifying a dead mystery snail can be difficult because the animals will sometimes float on the surface or be inactive for days on end.
You will need a little patience and a keen sense of smell to tell if your snail is dead after a week or so of inactivity.
Remove the snail and smell the foot. The foot is the small, flat portion right below the snail’s body that acts as a “door” to the shell.
The body will have a pungent, rotting odor if the snail is dead.
They are normally odorless, although poor water quality could lead to a bad smell.
Pull the foot back gently. The snail is still alive if it retracts its foot back into its shell.
Set the snail on a plastic sheet outside the tank and watch it diligently.
It will open its shell and begin to move around in search of water after a few minutes if alive.
They have lungs that allow them to breathe outside of water, so the snail will not be harmed.
Now the mystery of how long do Snails sleep solved.
We can sleep well this night (of course we sleep just few hours, not 3 years).
