Slug Eggs

So many times I've been asked what slug eggs look like. While I can try to describe them, showing the real thing is better. How about a photo? 

Today I came upon this.........

This is one of our flat slugs wrapped around a clutch of eggs. Is the slug being protective of its clutch? Or did it just recently finish laying eggs and it hasn't moved on yet? Most of the time when I find these eggs masses in the garden, there is a thin, semi-dry film of protective slime wrapped horizontally around the egg mass. This egg mass doesn't have that band yet, so perhaps they've been freshly laid....or the slug isn't done yet with the job.
