Watching a Banana Slug Eat

While recently camping on the Oregon Coast, my daughter noticed a giant banana slug. This slug was a beast measuring 8.5 inches in length! Over several hours, the slug moved from the ground to some low-hanging leaves of a Salal plant. The lower oval-shaped leaves were leathery, but the smaller leaves, just a foot away, were tender-looking and bright green. The slug found these smaller leaves within a short time and began to devour the newly-found meal. What was most amazing to me was that I have only seen banana slugs eating decomposing materials. This was the first time I observed one eating leaves. Also, because of the slug’s location, just a few feet off the ground, this was a great way to see how they eat. The slug’s mouth quickly closed and moved to the next section on the leaf, it is the microscopic teeth (or radula that can number up to 27,000) that make this creature even more fascinating. Below are some close-up pictures and a 2-second time-lapse video taken over about 3-minutes showing the slug eating.
