Trail of the Banana Slug

 

Last week my son and I found this banana slug on a trail near our house.  Banana slugs are huge!  According to The Western Society of Malacologists Field Guide to the Slug, by David George Gordon, they can grow to a length of 8 inches, with some reaching 10 inches.

 

 

As I’ve posted before, slugs breathe through a hole on their right side called a pneumostome.  It can be seen here close to its head.

 

And of course, that is one heck of a slime trail.  David George Gordon explains how this mucus allows the slug to move, makes it tougher for predators to grab it, and it absorbs water to prevent dehydration.  You might think it’s gross, but it is definitely useful!
