Why do banana slugs have a hole?
On the right side of the slug’s head is a hole that is called the pneumostome. Acting similar to a whale’s blowhole, the pneumostome moves air in and out of the banana slug’s only lung. Depending on the environment, this hole is opened or closed to maintain the slug’s moisture and oxygen levels.
