Le lumache - snails - are a popular food in Italy. They are also known as le lumache di terra - earth/land snails. Another name for a snail is una chiocciola. This word literally means 'a spiral' and refers to the shape of the snail's shell. The shell is il guscio.
There are all different ways in which they can be served and they come in different sizes ranging from small to large. Even sea snails - le lumache di mare - are an Italian food.
