Calma glaucoides from French Mediterranean

August 1, 2002
From: Patrick Heurtaux

Here are two photos of Calma glaucoides took in the Baie de Peyrefitte (near French/Spanish Mediterranean border), under stones in 4 m deep, in June, 2002. The size of the two slugs was about 20 mm. In one photo it is laying its eggs on two annelids worm tubes.

Best regards,

Dear Patrick,
Thanks very much for these photos. I have shown your photos to Gonçalo Calado who discovered a couple of years ago that there are in fact two species which have until now been confused as one. As you will see in his separate message, he considers your animal to be 'true' Calma glaucoides.
Best wishes,
Bill Rudman
