"Hello there. I'm whatever you want me to be."
Which comes in handy.
Since snails spend long times alone, and when they do come across another snail, the last thing they need to wonder is, "Is it my significant other half?"
Originally from Europe, now found in North and South America and a variety of places, the common garden variety snail is not so garden variety when it comes to sex.
They, after all, have the "love dart."
(It is advisable not to read the following until you've had a cup of coffee or caffeinated tea.)
According to Ronald Chase, a professor of biology at McGill University, garden snails court from 15 minutes to six hours by circling each other, touching tentacles, and biting on the lips.
Just before mating, hydraulic pressure builds up in the blood sinus surrounding the organ housing the dart, and when the second animal touches the darter's genitals, it fires that dart.
Evolutionary biologists believe these "love darts," if I understand this correctly, are coated with hormones that prevent a snail from destroying its own sperm with digestive enzymes.
So the species can continue.
To what end exactly?
These land-based mollusks feed on sick and struggling plants and are simply the cleaners of our gardens.
They tell us things.
Their slimy presence over your lettuce, while alarming, is a good sign that the environment for growing lettuce is not a good one.
Mollusks were among Earth's first inhabitants, dating back at least 500 million years, and land snails evolved from their sea cousins.
Some mollusks are covered by hard shells; others, like squid, are not. But they all lack skeletons.
There are more than 85,000 species and more we don't know about.
The mysteries of nature, as Albert Einstein said, “It is enough if one tries merely to comprehend a little of this mystery every day. Never lose a holy curiosity.”
In this mysterious world we live in, everything matters.
Even Helix aspersa.
