Are snails dangerous to human touch?

Snails are generally not dangerous to human touch, as they are harmless creatures. However, some species, like the cone snail, can deliver venomous stings that can be harmful or even fatal. Additionally, certain land snails can carry parasites, such as rat lungworm, which can pose health risks if handled improperly. Overall, while most snails are safe to touch, caution should be exercised with specific species and in certain environments.
