Re: self-fertilization

Hi Bill,
Regarding your comment on self-fertilization, there is a classic paper by Kawaguti and Yamasu (1961) suggesting self-fertilization in the bivalved sacoglossan Berthelinia limax. The authors isolated sacoglossans "just after they had thrown away their [larval] velar cilia"(p. 215). It would be very interesting to use molecular methods to see the extent to which populations of these slugs are inbred. A great PhD project for someone....

Dear Cynthia,
Thanks for reminding about this paper.
For those of you confused with names see my earlier comments on whether we should use Berthelinia, Tamanovalva or for that matter Endenttellina.
