Concerning message #19984:

"I thought the reddish parts in Asther Lau's photos were something to do with the camera lighting. If your animal actually had lines as red as in the photos it is a very unusual colour form."

Hi Dr. Rudman,
IN answer to your comments, I've seen three tiny Roboastra gracilis in the Similans (three separate locations) and they all had very red lines on the body. Unfortunately I had a camera with me on only one of those occasions.

Thanks Vie,
It would be interesting to know if you ever find specimens with the more usual yellow or yellow-orange lines. The only other photos I have seen of animals with reddish lines are specimens from Mozambique and South Africa [message #13250 ] so perhaps in the Indian Ocean region this reddish colour prevails. It will be interesting to see if anyone else has photos of animals with these reddish lines.

Best wishes,
Bill Rudman
