After a discussion about what he was shipping this is what came out:
When I bought them, they were sold as moina. They are still being sold as moina(if you buy it from the guy in LA, and the micro flex people, the moina will look the same thing). If your definition of moina is different, I am sorry.
Naming convention - I am not really into ID thing. People called them by that name, I just kept the name. I am not into going around and changing the way people ID things. If I did that, it will be hard to keep tract of thing.
Decide for yourself if you want to do buisness with someone who thinks like this.Moina is a common name. When you say moina, you still have hundred of different species. The same thing goes for ostracodes. As I indicate before, I am not into ID them. To ID them mean to write a publication and collects the sample. Our understanding of anything at this level is so primintive that you can fudge anything and the journal will publish them.
What people are buying - A source of food and something that will keep some of the worm alive longer. This moina or whatever does that function.
