What do snails eat? Do they eat other snails? Know now!

Before knowing what does a snail eats for the living, let us get to know a little about them.

Snails belong to the phylum MOLLUSCA and are GASTROPODS (one that are most diverse groups of animals, both in form, habit, and habitat). Which means you can find them in different sizes, colors, and shapes. Snails eat using their tongue like extension having thousands of small microscopic teeth. This organ is called the Radula. They use their Radulae (plural) very differently while they eat different types of food.

First off, some snails are carnivores, and some are herbivores.
Second off, some snails live above the water, and some snails live inside the water.
Next, some snails live in the freshwater, and some snails live in the seawater.

That’s the basic categorization of snails. Now, let us dig into what they eat.


What does a snail eat in general?

Snails can go eating anything from algae/plant/vegetable to eating other snails.

Garden snails eat pests, leaves, fruits, and vegetables. They also feed on dead animals and dead plant material. It plays a significant role in the natural food cycle as a decomposer.

Few aquatic snails are also herbivores as they feed on floating plants on the surface on ponds, rivers, and lakes. They also eat algae that grow on rocks using their Radulae to scrape them up.

Carnivore sea snails, as well as aquarium snails, feed on live worms, and insects, and even other snails.
