They feed by propelling food from the mouth into their intestines where it is digested. Snails and slugs both can live in aquatic or terrestrial habitats. The shell of snails are much more like an envelope that protects them from predators including humans and can expand when disturbed to increase their size. Snail bodies are covered with a shell that protects them from danger, while slug bodies are not covered with the shell. Snails and slugs belong to the same class and they both have many similarities like their movement, their food, etc. Large land snails are the major source of the dish's ingredients, largely because they are very nutritious, and it is best to avoid using sea snails because they can be poisonous to people. Many upscale restaurants serve cooked land snails as an appetiser called escargot. Snails are a delicacy in many nations, but particularly in France. Some snails can seal their shells and retract for added defence. Snails immediately retreat to their shells, especially when there are nearby natural predators. To their benefit, they make use of loose tree bark, stone slabs, and wooden planks. Slugs can easily, if slowly, fit into the smallest openings thanks to their lack of a rear shell and the capacity to compress themselves. The average snail can move at a speed of 1 mm/s. But snails cannot do this because the snail's body is covered with a shell and its foot sticks only in one place.ĭifferent snails and slugs move at various speeds. Slugs go backwards or sideways when needed. Slugs lack a muscular foot and they use their body to pull themselves forward on their belly or sides. Snails move around by using a muscular foot called a "foot" that sticks to the ground, while these animals move forward. The animal's soft tissue runs the risk of desiccating without a protective shell.įollowing are the Difference Between Snail and Slug: Snail vs Slug: Movement Slugs commonly employ a vestigial internal shell. Slugs lack a defensive shell or mobile house. Some snails can retract their shells completely. The snail has a large enough shell for it to duck into for protection. The main distinction between the two species is that the snail has an obvious shell while the slug does not. Both types of life can become dangerously dehydrated if they lose moisture to dry soil. They may move across the ground thanks to mucus. Both creatures leave behind a slime trail. However, both species can occasionally be found in water, even for brief periods. Snails and slugs are often found on dry land.
