What Is The Difference Between A Slug And A Snail?

Both snails and slugs are land gastropods. The only difference between the two is that slugs lack visible shells, while snails do. It is possible for slugs to have shells, but they are not as visible as snail shells.

Both slugs and snails are found in many different environments, including meadows, forests, gardens, and even your own backyard. Some animals, like birds or hedgehogs, view them as food sources, while others see them as pests that destroy plants and crops.


Snails have a distinct spiral shape to their shells, while slugs lack a shell that can be seen. The average size of a snail is 10 inches, while a slug’s size is 15 inches. In addition, due to their shells, snails are typically larger than slugs. On the other hand, slugs can grow longer than their cousins. 


Snails have it easy because they carry their homes. Their hard, protective shells allow them to retreat from predators. They can also rest inside their shells when it is raining or snowing.

Slugs, on the other hand, don’t have a shell to protect them and are often exposed to colder temperatures and harsher weather conditions. This makes them more susceptible to being eaten by larger animals. It is also easier for slugs to take shelter in narrow openings in logs, leaves, and other debris that they find on the ground.


Slugs are generally faster than their snail counterparts because they don’t need to pull their shells along with them. Although fundamentally different, both land snails and slugs travel in a similar fashion. They produce mucus to help them move forward, and they use their antennas as feelers for guidance.


The main difference between a slug and a snail is that slugs lack visible shells, while snails have one. Both species are found in many different environments, and they both play an important role in their ecosystems. Whether you see them as harmless creatures or annoying pests depends on your own point of view!
