Risbecia tryoni - trailing observations:

August 24, 2006
From: Hugues Flodrops


Dear Bill,
Another pair of Risbecia tryoni from New Caledonia don't confirm Asther M.Lau's suggestion [message #10918] that in trailing pairs ones with a few larger spots follow one with more small spots. Perhaps it is a coincidence, but it's seems there must be aother explanation.

Locality: Island " Ilot Canards", 2 metres, Noumea, New Caledonia, Pacific Ocean, 10 November 2004, apnea. Length: 50 mm. Photographer: Hugues Flodrops.

Bests Regards.

Dear Hugues,
As I said in reply to Asther's message, we have too little information to know whether her observation means anything. Certainly your animals show the opposite. Checking out suggestions like this is how we advance our knowledge so I always encourage 'bright ideas'. What we are basically looking for are patterns of behaviour which occur over and over again. At present there doesn't seem to be a pattern here. The major question still exists of course, and that is what is the reason for the trailing behaviour?

Best wishes,
Bill Rudman
