Summary
DescriptionLand Gastropod leaving mucus-conserving trail IMG 1674s.JPG |
English: Cornu aspersum (or Helix aspersa as it used to be) leaves a mucus-conserving trail when moving over an absorbent surface such as dry brick. Here the foot is raised in two places to avoid contact that would leave unnecessarily expended mucus. |
