Dino ID

[tymo92]

Sorry in advance for shaky video (holding camera). Is this amphidinium? Seems to be present with cyano.

Looks like Amphidinium on a first glance. The "beak" is what's giving it away.

Note that there are thousands of dinoflagellate species and if this one is actually part of the Amphidinium genera is nearly impossible to tell without DNA analysis.

You can find a few images in the identification guide: https://www.reef2reef.com/attachments/dinoflagellateid12_12_2019-pdf.1324729/

And a few more in my microscopy thread
