I can perhaps contribute something on the oweniids. There is really
very little information on oweniid reproduction except for several
papers on Owenia fusiformis that you can look up in Zoological Record.
However, for Myriochele oculata, there are some notes on that species
published by Oliver, J.S. 1984. Selection for asexual reproduction in
an Antarctic polychaete worm. Marine Ecology Progress Series 19:33-38.
The main study here is on Myriochele cf. heeri which Oliver found
undergoes asexual fragmentation in Antarctic waters. He also includes
observations on M. oculata in Alaska and has some notes about sexual
maturity and the like. He refers to another paper by Oliver, et al.,
1983. U.S. Fish. Bull. 81:501-512, where more information is developed.
For your information, Myriochele oculata should be referred to the
genus Galathowenia. Drop me a note if you want some taxonomic reasons.
I believe there is also some published information on Nereimyra, but I
will leave that to others to relate.
