Re: Sacoglossans vs Caulerpa taxifolia

Dear Bill,

Your query about the origin of the Cape Verde Ids and Canary Ids records raises a very difficult question. Obviously few sacoglossans have been collected at these localities till recent years. Also the fact that a number of Spanish malacologists have been working in the Caribbean and Central and South America in recent years may have made them more aware of amfi-Atlantic distributions. However, as even small pieces of Caulerpa are able to form new assimilators when given proper light and temperature conditions, it cannot be excluded that travelled (as egg masses or juveniles) on a torn off piece of Caulerpa. The fact that the Caribbean Elysia spp. with encapsulated or lecithotrophic development apparently have wider distributions than those with planktotrophic development is still a puzzle to me. I'd be glad to hear any other explanations.
