The name snail is most often applied to land snails, however, there are many different types of snails. In fact, there are over 4000 snail species that also includes different kinds of sea snails and freshwater snails.

Did you know that snails are gastropod mollusks that have shells and those without shells are known as slugs? Yes, a slug is a snail! Well, at least, they belong to the same class of animals. Mind-blowing!

Types of Land Snail

Let’s start by exploring some of the land snail types. However, you should know that some snails are amphibious types of animals. This means that that they can live on land and in water. These ones just prefer land more.

Cool Facts About Land Snails.

Giant African Land Snail

The giant African snail is an 8-inch long snail that’s originally native to Africa. However, they can now be found on every continent except for Antartica. They are one of the largest snail species.

The giant African snail has a high reproduction rate and has an insatiable craving for crops and vegetation in general. These two things make them an invasive species of snail. Despite this fact, some people think that they make good pet snails.

They have light to dark brown colored shells and some have vertical stripes on their shells that are usually a darker shade of brown.

On average, a giant African land snail can live for 5 to 7 years. However, there’s evidence to suggest that they can live up to 10 years as well.
