When you see snails in your garden or near water, you might ask, “What do snails eat?” These slow-moving creatures eat a mix of plants, algae, and even decaying organic matter. In this guide, we’ll explore their diet and share simple tips to manage snails in your garden.
What Do Snails Eat?
Snails eat a variety of things, depending on their type, age, and habitat. Most land snails are herbivores, which means they like to eat plants. You might find them in your garden munching on leaves, fruits, and even bark or stems from your plants.
Some snails also eat mushrooms and fungi. Freshwater snails often eat algae that grow in ponds, tanks, or aquariums. Other snails eat dead plants or animals. These are called detritivores because they feed on old, decaying matter, such as leaves or animal remains.
There are also carnivorous snails that hunt tiny animals, such as slugs, worms, or even other snails. One kind, called Powelliphanta, lives in New Zealand and eats earthworms. Some snails, like Rumina decollata, are omnivores and eat both plants and small animals.
Snails need calcium to keep their shells strong, so they eat things that help with that. They have a strong sense of smell to help them find food. Most snails look for food at night or early in the morning because they are nocturnal.
When it’s getting cold, snails eat more to store fat for hibernation. In hot weather with limited food, they may enter a deep rest called estivation to survive dry conditions.

What Do Snails Eat in the Garden?
Snails in your garden can be helpful sometimes, but they can also cause trouble, especially when it comes to your plants.
They love leafy greens, such as lettuce and spinach. You might notice big holes in the leaves. That’s a sign snails have been snacking. These holes can slow down plant growth or even ruin your veggies.
Snails also enjoy fruits and flowers that grow close to the ground. Strawberries and tomatoes are among their favourites. If they eat the fruit before it ripens, it can ruin the whole crop.
Seedlings, or baby plants, are one of their top picks. Snails can chew them right down to the stem. That means the plant never gets the chance to grow up. It can be disappointing if you just planted new seeds.
Even herbs like basil, mint, and parsley aren’t always safe. Snails don’t usually like strong smells, but if they’re hungry, they might eat them too.
What Do Aquatic Snails Eat? What Do Snails Eat
Aquatic snails live in all kinds of water, like ponds, rivers, and even the ocean. What they eat depends on where they live, but they’re not too picky.
In freshwater places, like ponds or tanks, many snails are herbivores. They enjoy soft water plants, such as duckweed, Azolla, and water lettuce. They also help keep things clean by munching on algae that grow on rocks, glass, and decorations.
Snails that live in the ocean often snack on seaweed and tiny microalgae. However, not all aquatic snails are herbivores.
Some snails are omnivores, which means they’ll eat both plants and other stuff. They can also feed on rotting leaves, dead fish, or even old pieces of insects that sink to the bottom of the water. These snails are like nature’s little clean-up crew; they help keep the water clean.
Because they can eat many things, aquatic snails can live in lots of different water homes, from muddy ponds to clear oceans.
What Do Newly Hatched Snails Eat?
Baby snails, called hatchlings, start eating right after they hatch. Their first food is the shell of the egg from which they came. This may sound unusual, but it’s helpful. The egg contains calcium, which baby snails need to make their tiny shells strong.
Sometimes, they might also eat parts of unhatched eggs or even non-living siblings that didn’t survive. This gives them extra nutrients to grow healthier and stronger.
Before they come out of their hiding place underground, the baby snails also eat some of the dirt around them. This not only feeds them but also helps them dig their way to the surface. Once they reach the outside world, they begin to eat soft plants and other foods.
How Do Snails Eat?
Snails eat in a cool way. They have something in their mouth called a radula. It’s like a tiny tongue, but it’s covered with small teeth.
When a snail finds food, it scrapes or rubs the radula over the food to break it into little pieces. This helps them eat things like soft plants, algae, and even harder stuff like old shells or things stuck to rocks.
As they keep eating, the tiny teeth on their radula wear down, just like a pencil gets dull when you use it. But snails grow new teeth all the time. Snails that eat tougher food, like meat or other snails, wear their teeth out faster, so they develop new ones more often.
When Do Snails Look for Food?
Snails like to look for food when it’s dark and cool outside. That means they usually come out at night or early in the morning when the sun isn’t hot, and the ground is still a bit wet. They dislike heat and dry weather, so they stay hidden during the day.
As winter gets closer, snails eat a lot more than usual because they need to store fat to help them sleep through the cold months.
In very hot or dry weather, such as in summer or spring, some snails enter a deep state of rest called estivation. It’s their way of saving energy and staying safe until things cool down and get wetter again.
What Do Snails Drink?
Snails need water to stay alive, just like us. Almost 90% of a snail’s body is made of water. They need this water to move, stay healthy, and perform all the functions that snails do.
Snails get water in a few ways. They absorb moisture from their food and sometimes even soak it up through their skin when the ground is wet. But sometimes, that’s not enough. They also drink water when needed, especially if they are very dry or thirsty.
If a snail doesn’t get enough water, it starts to dry out and move much slower. It might even look thinner or sick. That’s why snails love damp places like gardens after it rains. Wet spots help them stay hydrated and healthy.
Conclusion
Snails may be small, but they have some really interesting eating habits. From fresh plants and fruits in the garden to algae and decaying matter in the water, they eat many different kinds of food depending on where they live. Some snails even eat other tiny animals. They also need water and calcium to stay healthy and strong.
