I have a plastic dustbin in use as a water butt one side of my

I often find slugs around the inside of the bin rim and knock them into
the water. They always sink towards the bottom but more appear quite
regularly, hence my question.

With me, some seem to survive and escape and others drown. It is
possible, I suppose, that the unlucky ones have found themselves in
water where some plant food residue lingers ... or perhaps different
types of slug have evolved to live and cope in wetter ground. I'm sure
the latter is a possibility. I have never seen a slug doing the breast
stroke, for which I am heartily grateful!
