What is the world's largest type of snail?

The world's largest type of snail is the African Giant Snail (Achatina achatina), which can grow up to 8 inches (20 cm) in length and 4 inches (10 cm) in diameter, with a weight of up to 2 pounds (0.9 kg). These snails are native to Africa but are now found in many parts of the world, where they are considered an invasive species.

African Giant Snails are hermaphrodites, meaning they have both male and female reproductive organs. They are known for their voracious appetite and can eat over 500 different types of plants. They are also known for their large, spiral-shaped shells, which can be used for decorative purposes.

Despite their size, African Giant Snails are not dangerous to humans. However, they can carry diseases and parasites, so it is important to handle them with care and avoid eating them.
