International Kissing Day
Snails ‘kissing’ in Sambas Regency, Indonesia

Happy International Kissing Day! These snails aren’t really kissing, at least not in the human sense, but it sure looks like it. Land snails do engage in courtship rituals that involve plenty of touching, though. Scientists are still sorting out the mysteries of snail mating habits, given some of the animals’ surprisingly complex biology. If you decide to celebrate International Kissing Day, remind the object of your affection how nice it is that you aren’t covered in slime like a snail … or don’t. You know what? Forget about that last part.

Snail is a common name that is applied most often to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also applied to most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word snail is used in this most general sense, it includes not just land snails but also thousands of species of sea snails and freshwater snails. Occasionally a few other molluscs that are not actually gastropods, such as the Monoplacophora, which superficially resemble small limpets, may also informally be referred to as “snails”.
