I think it's a Gonyaulax because of it's very angular shape and it's ornamented theca, but if someone can help me to identify this cell, I will thank you.
This cell has been found in a brackish and eutrophicated water.
Hello Amandine,
For file"3gonyaulax.spiniferaMB.a.S3.T1.15_02_17" my suggestion is:
Gonyaulax sp.
And the File "4gonyaulax.MB.b.S3.T1.15_02_17" - I'm not sure but it looks like Scrippsiella trochoidea
Thank you for your two answers.
For me, Scrippsiella trochoidea is more rounded, with no spine or horn, so I'm not sure that it's this. I have some photos of cells that I identified as probably Scrippsiella sp. (here after).
But thank you for the first photo, it's reinforced my idea.
Best wishes,
Amandine
Hello Amandine,
I think judging by my personal experience that the last two pictures are also Scrippsiella trochoidea. Of course since this is a different water areas, and the fact that speaks of the existence of complex Scrippsiella, the most exact definition should probably be approached with a detailed morphological or genetic analysis.
Best wishes,
Dimitar
