That Slug Life

The Life and Times of a Banana Slug

I use my slime to breathe, to move and to attract water. In fact my slime absorbs 100 times its volume in water. It helps me move along the ground under the redwoods and even climb up trees. My slime is a liquid crystal that acts both like a lubricant and an adhesive. So the next time you see my glistening slime think about all the great things it does for me.
