Philinopsis gardineri from Reunion Island

December 1, 2006
From: Philibert Bidgrain

Concerning message #15398:

Dear Bill,
We found three specimens of this species in Kelonia Center (a Marine Turtle Center).These specimens have a rounded anterior body margin and a protruding bubble shaped head, not truncated like in P. cyanea.
What's your opinion about these specimens?

Locality: Saint Leu, Reunion Island, Indian Ocean, 27 November 2006. Length: 20 to 45 mm. Photographer: Philibert Bidgrain and fFrançois Beudard.

Last year, I send you a photo of P cyanea egg mass, with a characteristic sausage-shaped structure [#15333]. Have you got any information about P gardineri egg mass?

Dear Philibert,

As I said last year [message #15435], the high rounded bump on the head is a sure sign this is Philinopsis gardineri rather than P. cyanea. It is interesting to see animals with the yellow marks on the body. I can't  recall seeing specimens of this species with such marks before, usually it is a uniform dark blue-black.

I would certainly be interested in photos of the egg mass of this species. We don't have any information on it.

Best wishes,
Bill Rudman
