Beat the Mediterranean heat by claiming the high ground.
Theba pisana is a small land snail native to the Mediterranean region. It is especially common in southern Europe, North Africa, and coastal areas with warm and dry climates. The species is abundant in Greece, including Crete, where it can often be found resting on grasses, shrubs, fences, and rocks during hot weather.
This snail is highly adaptable and has spread to many other parts of the world through accidental introduction via plant trade and agricultural materials. Established populations exist in countries such as Australia, the United States, South Africa, and parts of South America. In some regions it is considered an invasive agricultural pest because large populations can damage crops and vegetation.
The shell of Theba pisana is usually white or cream-colored with variable brown, tan, or yellow spiral bands. Some individuals have thin delicate lines, while others display darker and more contrasting patterns. The pale coloration helps reflect sunlight and reduces heat absorption in hot Mediterranean environments.
Adults are generally small, with shells reaching approximately 12–15 mm in diameter. During dry summer periods, these snails often climb vegetation and remain inactive in large groups to avoid overheating and dehydration.
