As we start to figure out how to propagate these guys, I thought I’d share a little of the life cycle.

First, when two slugs love each other very much, they become very close.  Because they are hermaphrodites, anyone they meet is a possible partner.  Since fattening up on Bryopsis, they have been in the mood for love rather frequently.  Yes, there really are two slugs in this photo.

The next morning, there was a nice egg mass.  In fact, there were two, one on each side of the plant.

Since I knew within about 12 hours when the mass was laid, it seemed like a good idea to collect it and get a better sense of how long the eggs take to develop on the bookshelf.  Time permitting, I have been taking photos of the embryos during their development, and they should appear shortly.
