Is this a Dino?? Please identify. It doesn't move at all

Can anyone identify these. They do not move at all. It was a fresh sample placed immediately under the microscope. Last week I thought perhaps it was a dead Dino, but today's sample is the same. Absolutely no movement. Prorocentrum???

Oh fantastic. I'm thrilled. I'm battling Dinos in my 180 gal. This is my 90 gal. I can clean my glass. Thank you, thank you, thank you taricha.

OrchidMiss I'd rather find those in my 180 than what I have. LOL
