| Scientific classification |
The Hemicycla plicaria is a special type of land snail. It belongs to a group of animals called gastropods, which includes snails and slugs. This snail is part of the Helicidae family, which is a common group of land snails.
This snail is endemic to Spain. This means you can only find it living naturally in Spain and nowhere else in the world! It was first described by a scientist named Jean-Baptiste Lamarck in 1816.

What is the Hemicycla plicaria Snail?
The Hemicycla plicaria is a fascinating creature, known for its unique shell. Like all snails, it moves slowly on a muscular "foot" and carries its home, a spiral shell, on its back. Snails play an important role in their ecosystems, helping to break down plant material and recycle nutrients.
Where Does This Snail Live?
This particular snail lives only in the Canary Islands, which are part of Spain. These islands are known for their amazing and unique wildlife, and the Hemicycla plicaria is one of those special animals. It prefers to live in damp, shady places, often found under rocks, logs, or in leaf litter. This helps it stay moist and safe from the sun.
What Does It Look Like?
The shell of the Hemicycla plicaria is usually a brownish or yellowish color, often with patterns or bands. It has a spiral shape, which gets wider as it grows. The shell helps protect the soft body of the snail from predators and from drying out. Snails have two pairs of tentacles on their head. The longer pair has eyes at the tips, which help them sense light and darkness. The shorter pair is used for touch and smell, helping the snail find food and navigate its surroundings.
What Does It Eat?
Hemicycla plicaria snails are mostly herbivores, meaning they eat plants. They use a special ribbon-like tongue called a radula to scrape off tiny bits of plants, fungi, and algae from surfaces like rocks and leaves. They are important decomposers, helping to clean up the environment by eating decaying plant matter.
Life Cycle and Reproduction
Like many land snails, Hemicycla plicaria snails are hermaphrodites. This means each snail has both male and female reproductive organs. When two snails meet, they can both exchange genetic material and lay eggs. They usually lay their small, round eggs in moist soil or under rocks. The eggs hatch into tiny snails that look like miniature versions of the adults. These young snails grow by adding new material to their shells, slowly getting bigger over time.
Is the Hemicycla plicaria in Danger?
Unfortunately, the Hemicycla plicaria is considered a critically endangered species by the International Union for Conservation of Nature (IUCN). This means it faces a very high risk of disappearing from the wild. Its habitat is shrinking due to human activities like building and farming. Climate change also affects its environment. Efforts are being made to protect its natural habitats and ensure this unique snail can survive for future generations.
