4. Mar:

In some years starting from march strange fuzzy animals can be found at mussel beds or washed ashore. They are 4 - 10 cms long and have a smooth foot underneath the whole body which marks them as slugs. The head bears four tentacles, the back is covered in dozens of fringes. They harbour gut appendices which store nettle cells that origin from the prey of the Anemone slug: Plumose anemones and Mud sagartias. The Anemone slug occurs in different colour variations, is adult in spring an lays spiralled gelatinous egg strings.
