The Helix genus includes some of the world's most famous land snails, like the large Roman snail (Helix pomatia) and the common garden snail (Helix aspersa). Known for their globular shells and slow-motion lifestyles, these air-breathing mollusks are native to Europe and the Mediterranean but have traveled globally as both a delicacy and accidental hitchhikers.
Instead of traditional teeth, snails have a tongue-like organ called a radula covered in thousands of tiny chitinous teeth. They use it like a "bucket-wheel excavator" to rasp and grind down their food.Retractable Eyes: Their larger upper tentacles hold their eyes, while the lower pair helps them "feel" the ground. Both can be pulled back inside their heads for safety.
