These seem to be slugs. There were six on this piece of garden edging when I turned it over. I've never seen any thing like these before.

" Feeding and Diet

The Red Triangle Slug is usually found grazing on microscopic algae growing on the surface of smooth-barked eucalypt trees, leaving behind scalloped tracks as it goes. If given the chance, it will also remove bathroom mould."

I found them within a metre of the base of a substantial lemon-scented gum.
