What is a Snail?

A snail is a type of mollusk and belongs to an animal group called gastropods. They have a slimy body, and most of them, including the common garden snail, have spirally-wound shells on their backs. The shell protects the snail from predators and desiccation. Snails range in size from the microscopic varieties to the larger species that reach up to 8 inches in length.

Snails can be found in most habitats, from the seaside to forests, fields and gardens. They are nocturnal animals and usually come out at night to eat fungi, lichens, algae, and dead plants. Some species are carnivorous and feed on worms and insects.

There are over 50,000 species of snails around the world and they can be classified into four main types: land snails, fresh water snails, sea snails, and semi-terrestrial snails. Land snails are terrestrial animals and amble along on a single foot. Freshwater snails live in shallow and deep bodies of water. Sea snails live in the ocean and have adapted to life in salt water. Semi-terrestrial snails are amphibious animals and spend time both on land and in the water.

Anatomy of a Snail

A snail’s body is composed of several different parts. These include the head, tentacles, foot, and a shell. All of these parts work together to help the snail move, survive, and reproduce.


The head of the snail is located in the front of the body. It is where the eyes and mouth of the snail are found. The snail has two pairs of tentacles, one pair that reaches out for sensing and the other for eating. These tentacles can also be used to help the snail navigate its surroundings.


The foot is located at the bottom of the snail’s body. It is used for movement and helps the snail to crawl. The foot is also an important part of the snail’s ability to cling to objects and climb.


The shell of the snail is a hard, protective covering for the snail’s body. The shell is composed of calcium carbonate and can be a variety of colors and patterns depending on the species of snail.

Internal Parts

Inside the body of the snail, there are several organs that help the snail survive. These organs are the gills, lungs, heart, stomach, intestine, reproductive organs, and brain. All of these organs are important for the snail’s ability to respire, digest food, regulate its internal environment, and reproduce.

Life Cycle of a Snail

The life cycle of a snail is fascinating and interesting to learn about. Snails start as an egg and go through several stages before becoming an adult.

Snail eggs are small and translucent. They are usually deposited in moist soil or under stones or logs where they will remain until they hatch. All land snails, including the common garden snail, produce only one type of egg, which is small and white in colour. The eggs will start to develop within a week, at which point the eggs will start to turn a yellowish hue.

After the eggs hatch, the baby snails, or hatchlings, emerge from the eggs and look very similar to the adult version. After hatching, the baby snails will grow quickly, depending on food availability and other environmental factors. The time taken for the snails to reach maturity varies depending on the species, but most snails take a few months to reach full size.

Once the snail reaches adulthood, it is capable of reproducing and laying eggs. The number of eggs laid by a female snail depends on the species, but the average is approximately 60 eggs per clutch. Some species can lay up to 400 eggs at once!

It is important to note that the lifecycle of a snail can be significantly affected by its environment, so even if two snails of the same species are kept in identical conditions, they might not mature at the same rate.

Reproduction of Snails

Snails can reproduce both sexually and asexually, depending on species. Most snails mating habits involve two separate individuals, during which the snails will pass sperm from one to the other. This will then take place in the form of an egg-laying ceremony where the snail will lay multiple small spherical eggs in a safe and moist location.

The method of egg laying can also vary between species. Some may lay their eggs in water, while others prefer soil or some other humid environment. Most species of snails lay their eggs in clusters with a jelly-like substance used to bind them together.

Fertilization of the eggs is normally done externally, meaning that sperm must be present for the eggs to develop. This leads to a higher mortality rate among the eggs, as many are lost due to predators or environmental conditions like drought or extreme temperatures.

The Lifespan of Snails

The lifespan of a snail varies greatly depending on the species and their environment. While some species can live up to 10 years, others will only live a few weeks. The average life of snails is usually 2-5 years, depending on the weather conditions and availability of food. Snails are sensitive to extreme changes in temperature and humidity. They need a temperature between 40 and 80 degrees Fahrenheit, with a good amount of moisture. Generally, snails go into hibernation in cold temperatures, and this can prolong their lifespan if done correctly.

In their natural habitat, snails face many threats such as drought, floods,and predators. If these threats exist in an environment, they can decrease a snail’s lifespan significantly. It is important to note that snails have much more control over their lifespan in a captive environment. In a controlled space, they are protected from external factors and can generally have a longer lifespan.

A snail’s behavior can also affect how long it will live. A healthy diet, avoidance of extreme temperatures, and active movement can all increase a snail’s lifespan. However, if a snail eats unhealthy food or does not escape extreme temperatures, its lifespan can decrease.

The life span of a snail plays an important role in its reproductive cycle. In many species, snails will only reproduce when they reach a certain age. As such, having an increased lifespan means that a snail can reproduce more often and expand its population.

Predators of Snails – Enemies Natural or Otherwise

Snails may seem like gentle, slow creatures, but they need to watch out for predators who have them in their sights. While snails are usually very good at protecting themselves from predators through their strong, thick shells and defensive secretions, they do have a few natural enemies.

Animals like lizards, birds, frogs, snakes, rats and possums are all known to hunt snails for food. They will find them by following either their trails or scent, and break through the shells with their sharp beaks or claws. Other predators will also use their tongues, which contain hundreds of small, sharp teeth to eat the soft bodies of the snails. Even other snails have been known to prey on their own species.

In addition to natural predators, there are a number of other animals and insects that can harm snails. These include mice, slugs, ants, flies and certain types of beetles. There are also various fungi and bacteria that can infect and kill snails.

Finally, humans can also be a danger to snails. People often use snail bait, which contains a toxic compound designed to kill off the creatures. Additionally, some people collect snails as pets, which can cause problems when the population is over-harvested.

Care and Preservation of Snails and Their Eggs

Captive breeding can be a great way to conserve snail species. It provides an opportunity to have a safe, controlled environment for snails and their eggs. When creating the ideal conditions, it’s important to replicate the environment of the snail’s natural habitat as closely as possible. This means including the right temperatures, humidity, substrate, plants, and rocks. It’s also important to have enough space for them to move around and socialize.

The optimal temperature for most snails is around 64-72°F (18-22°C). Some species need slightly higher or lower temperatures, so it’s best to research the preferred conditions of your species. The same goes for humidity – some prefer a higher humidity level, while others thrive in lower humidity environments.

Providing the right substrate for snails is also essential. Distilled gravel, pebbles, coconut coir, and soil are all options. Whatever substrate is chosen must be free from any chemical additives and should have the correct pH balance. Additionally, adding non-toxic plants (real or artificial) and rocks to the enclosure helps to make the snails feel secure and creates an overall nicer environment.

Snail Eggs as Food

Snail eggs have been used in various cuisines around the world for centuries, even predating the Roman Empire. Although it is not a common ingredient in modern western cooking, it has featured heavily in French cooking and other European countries. In East Asia, snail eggs are also widely consumed, either raw or boiled.

In addition to being used as a traditional ingredient, snail eggs are a great alternative for vegans and vegetarians wanting to add more protein to their diet. The eggs are high in certain minerals such as calcium, and have a low calorie content. It can be served as a side dish, added to salads or soups, or simply boiled as a snack.

When buying snail eggs, it is important to ensure that they have been ethically sourced as many snails are over-harvested for food or kept in inhumane conditions. Also, only buy from certified suppliers – wild snails can carry parasites and harmful bacteria which could prove dangerous to humans.

Because of its relatively low profile, snail eggs can be quite difficult to come by, so it is best to check with local farmers or specialty food shops. For those who don’t have access to snail eggs, there are many vegan substitutes that can be used for a similar effect.

Snails As Pets

Snails can make interesting and unique pets, but they require a lot of care. Many people fail to realise the effort that is required when looking after snails. If you’re considering getting one as a pet, it’s important to know what to look out for and how to care for it.


A well-established habitat is necessary when keeping a snail. The home should have a mix of wet and dry spots, as well as plenty of hiding places, such as small plants or rocks. To provide humidity, water should be added to the tank regularly. Nutrient-rich soil should also be included at the bottom of the tank, with space for the snail to move around and explore.


Snails are omnivores, and will eat fresh fruits and vegetables, as well as dried food and other commercial products specifically designed for snails. Make sure not to overfeed your snail as this can lead to health problems down the line.

Health and Cleaning

It’s important to check your snail regularly to make sure it looks healthy. The shell should be glossy and clean, and the foot should move freely. Clean the tank regularly, removing any uneaten food or droppings.

Safety Concerns

Snails can be easily harmed by sudden temperature change, stress or injury. Make sure children do not play roughly with them, and try to keep them away from other animals in the house.


Snails can be great additions to households, and can even become part of the family. They don’t need much attention, but it’s important to give them the correct environment to thrive in. Knowing the proper care techniques is key to a healthy and happy snail.
