Maybe my picture is not the best, but I want you to show a seawater-plankton animal which I like very much. It is the cladoceran Evadne normanni (about 900 µm long).
There are only few cladocerans in seawater. "Cladocerans are typical limnic crustaceans.....Only a few species secondarirly invaded the marine pelagial" (Larink&Westheide, Coastal Plankton, München 2006, p. 92).

Hallo Franz,
can you take a picture with polarized light, to look for crystals?
Regards
Ernst

Hello Arturo, Rogelio and Ernst,

Ernst: next time I will look for crystals.
