Dear Bill,
The yellow "string" in the Elysia subornata egg mass is the extracapsular yolk. The egg capsules and embryos are unfortunately out of focus. The same type of egg mass is found in at least 3 Caribbean species of Elysia - E. tuca, E. subornata & E. pratensis, and possibly also in one or two undescribed species (from Caulerpa).

Best regards,
Kathe

Thanks Kathe,
It is a very strange arrangement - it would be very interesting to know if the larvae actually derive any nourishment from this 'yolk'. Not only is it outside their individual development capsule, but outside the mucus egg ribbon which supposedly protects them from adverse environmental dangers.
Best wishes,
Bill Rudman
