Slugs - Ugh!

Probably not too many people would name the slug as their favorite creature, particularly me. But since moving to western Washington 14 years ago, I have become better acquainted with the gooey gastropods. When I go for my morning walk, I have to spend more time looking down than I'd prefer, in order to avoid stepping on one of them. And I've noticed something interesting about them. When they cross the road, they frequently get run over by a car. However, if they're only partially smashed, the portion that remains intact seems to be able to grow a new end and survive. I frequently see an obviously truncated slug creeping slimily along.

I tried to find out more about this on the internet. Although there seem to be a lot of articles about this in professional journals, which I am not able to access, I did find a few sites which mention that several invertebrates, such as slugs, salamanders, and starfish are able to regenerate lost parts. Apparently researchers hope to someday utilize information gained from these creatures to help humans to regenerate lost parts.

If there's a lesson to be drawn from this, I guess it would be that when our lives seem to be smashed, we can learn to build a new life on the ruins of the old one.
