Land snails, relatives of seashells, are well-known for their beauty, vivid colors and exquisite patterns. About 35% of the world's land snails are found in the Philippines, and almost all of them are endemic to the country. Due to their extreme sensitivity, many have become extinct in their rain forest environments as a result of deforestation. Most land snails will not survive when transferred to other environments, so it is only by saving our forests will we be able to save our land snails. 

The following endemic land snails of the Philippines are featured:
