The suprapedal gland or mucous pedal gland is an anatomical feature found in some snails and slugs. It is a gland located inside the front end of the foot of gastropods. The term suprapedal means "above the foot". The function of this gland is to produce mucus. The gland opens on the front end of the sole, on the ventral side of the foot. The mucus produced by this gland becomes a thin layer covering the sole of the foot, and this helps the gastropod in moving.
