Slugs only have one nose. It’s a common myth that slugs have 4 noses, but this isn’t the case. A slug’s features and sensory organs are found in tentacles on its face. A pair of tentacles hold each eye, while another pair of tentacles underneath contains nostrils. The four-pronged appearance of a slug’s face gives the illusion that it has four “noses.”
