I am pleased to introduce you to
Arion rufus, commonly known as the Giant (or European) Red Slug. Though it is now common here it is an introduced species not native to this area. In the video below you may notice it appears to be dragging something from its tail. This not an accident. This is the site of its
caudal mucous pit, a cunning anatomical structure that re-absorbs the slime that the slug secretes to make its passage smoother.
