Aplysia punctata mating
November 27, 2003
From: Jim Anderson
Dear Dr. Rudman,
We found these Aplysia punctata today. 4 of them, approx 85mm long, in a ball all connected. In 11.5 deg C water at 12 M at Maiden Island near Oban on the west coast of Scotland. I seperated them out to see what would happen. They were placed about 250mm apart and within 5 minutes had reassembled. Initially they 'reared' up from the bottom tasting/smelling the water then headed more or less for one another. I didn't see the final agregation (shortage of air!) but they were nearly all there.
Regards,
Jim A

Thanks Jim,
Mating aggregations are certainly a common occurrence among Sea Hares. I included a close-up of the head of one of the animsls as it shows the typical colour pattern. I have just noticed that it seems to have had an accdent with its rhinophores and is apparently growing new tips
Best wishes
Bill Rudman
