It is likely that nereidids are the best candidates for invertebrate model annelids, perhaps Platynereis dumerilii being the most researched? I should also like to recommend the papers of  the 1999 volume of Hydrobiologia 402, republished in hardback by Kluwer as Developments in Hydrobiology 142, edited by Adriaan Dorresteijn and Wilfried Westheide. Its title is ' Reproductive Strategies and Developmental Patterns in Annelids.

Two additional references with polychaete connections just noticed:

Baker, M.E. (2008). Trichoplax, the simplest known animal, contains an estrogen-related receptor but no estrogen receptor: Implications for estrogen receptor evolution. Biochemical and Biophysical Research Communications 375(4): 623-627. 

Tsai, P.S.; Zhang, L.H. (2008). The Emergence and Loss of Gonadotropin-Releasing Hormone in Protostomes: Orthology, Phylogeny, Structure, and Function. Biology of Reproduction 79(5): 798-805. 

Please can I request that when listers post references they should do it after the conventional citation style as above? Undisguised raw output pasted straight from commercial databases may just get us into trouble over copyright. If I notice it I will kill the posting and ask the poster to reformat, making it less obvious. Thank you.
