Hi Bill

I thought I'd share a few shots I took this morning of two Melibe (viridis?) mating. As I coaxed the two individuals apart it was quite easy to make out a star-shaped opening on their right sides (pic 3). The small appendages that comprised this star-shaped opening seemed to extend out in search of the partner and reconnected very quickly.

Locality: Tasi Tolu, 18 meters, East Timor, Banda Sea, 01 November 2008, sandy slope. Length: 10 cm. Photographer: Brian Francisco.

We saw 6 or 7 individuals this morning, but no egg ribbons.

Dear Brian,

There could well be a ring of papillae like we can see in your lower photo, around the genital opening of the darker animal on the left. Just to make it clear to other readers, what you can see in the lighter brown animal on the right is its head and oral hood. I assume when Brian coaxed them apart, the right animal started moving around.

Best wishes,
Bill Rudman
