Snails need moisture to survive; so if the weather is not cooperating, they can actually sleep up to three years. It has been reported that depending on geography, snails can shift into hibernation (which occurs in the winter), or estivation (also known as 'summer sleep'), helping to escape warm climates.
True or False: Snails Can Sleep for 3 Years
This is false: Snails can't sleep for three years. Some snails hibernate at winter, or go into a period of estivation during summer. It is thought that this last for up to three years, but it is rarely noted to last for quite that long in reality.

Pond snails use things like rocks or the side of their aquarium as their bed, attaching themselves while they sleep. Although this might not seem particularly relaxing, their shells do hang away from their body, and they keep their tentacles inside their shell.
The average sleep cycle of a snail isn't too astounding. Snails will sleep on and off for several hours at a time. Once they've rested though, they can stay awake for around 30 hours. You may even know a few people with similar sleeping patterns.
You can wake them up by keeping them warm and gently running the shells under tepid water. Once the snails are happy the conditions are going to remain warm they will become active again. Around once a month the tank will need to be thoroughly cleaned and the substrate replaced.
Do snails have teeth? It turns out, they do. "My snail," Elizabeth learned, "possessed around 2,640 teeth ... The teeth point inward so as to give the snail a firm grasp on its food; with about 33 teeth per row and maybe 80 or so rows, they form a multitoothed ribbon called a radula."
Look out the snail's shell and body closely. When a snail dies, its body shrinks into the shell and then slowly decomposes. Look at the opening of the shell, if you cannot spot the body inside, it is most likely a dead snail. Also, when you hold the snail and it feels very light with nothing inside, the snail has died.
Snails have the most teeth of any animal
A garden snail has about 14,000 teeth while other species can have over 20,000. But that's not even the most shocking part: The teeth of an aquatic snail called the limpet are the strongest known biological material on Earth, even stronger than titanium!
NATURALIST SAYS SNAILS SNORE, SLEEP SOUNDLY, BESPIEE AUDIBLY — Los Angeles Herald 1 July 1906 — California Digital Newspaper Collection.
Koalas. Hats off to the (somewhat disputed) king of sleep: the Koala bear. They've been reported to sleep up to 22 hours a day in captivity, over 90% of their lives. In the Australian wild, that figure may be closer to 14.5 hours of sleep daily, boosted by 5 additional hours of rest and inactivity.
Koala – 22 hours
Koalas are thickset arboreal marsupials with a thick grey fur. Found only living in Australia, they mainly live in the eucalyptus trees and spend around 22 hours of their time sleeping (90%).
The Brown Bat has one of the longest sleep times at 19.9 hours/day, while the Giraffe has one of the shortest sleep times at 1.9 hours/day.
To keep moisture locked in during sleep or hibernation, especially during dry seasons, snails adhere to estivation. In this process, snails curl up in their shells and secrete mucus to keep them safe from extreme external conditions.

Land snails that are kept in a tank with a lid on will often climb and hang upside down from the lid. They can do this because the SLIME is sticky and creates SUCTION.
Garden snails rely on their excellent senses of touch and smell to find food. They have very poor eyesight and are deaf to sound.
Garden snails generally hibernate during winter. They have both female and male reproductive cells (they are hermaphrodite). They don't actually need to mate with another snail in order to reproduce, self fertilisation is possible. After mating they lay around 80 white eggs in a damp, underground nest.
Snails: Even though their mouths are no larger than the head of a pin, they can have over 25,000 teeth over a lifetime – which are located on the tongue and continually lost and replaced like a shark!
But floating might seem a bit abnormal. Floating isn't usually a sign that your snail has passed away, although it might indicate that he's unhappy with the water. Some snails float because of trapped air in their lung, while others eat away at film at the top of the water surface.
A floating snail is not necessarily dead as it may be using an air bubble trapped in its shell to regulate buoyancy and move to a different location. Snails can float due to the presence of an air bubble trapped in their shell. The air bubble acts as a buoyancy aid, helping the snail to stay afloat in water.
The fact that your snail is floating doesn't necessarily mean that your snail has passed away, although it could indicate that the snail is uncomfortable with water. Certain snails float due to trapped air in their lungs and others eat away the film that sits on high points of the water surface.
It might look like some snails have four eyes – two taller ones at the top of the head plus two shorter ones below. The ones at the bottom are not eyes, however. Instead, they act as a nose-like organ. Snails use their sense of smell to find food, locate predators, and more.
Snails hearts have a single auricle receiving blood from the lung and a single ventricle that pumps blood to the rest of the body, much like it does in humans.
Snails, spiders and octopi have something in common- they all have blue blood! We're not talking in the sense of royalty, these creatures literally have blue blood. So why is their blood blue and ours red? One of the purposes of blood is to carry oxygen around the body.
