Hello Francisco.
Perhaps a rotifero going out of its cyst?

To me, it looks like an animal, not a protist. But what it is, I cannot say.

Francisco,

Really excellent and interesting video. Thank You for posting!

It is an early stage larva of a bivalve mollusc. Known as a D-larva or D-veliger. The "D" refers to the overall shape of the shell. The straight edge is the hinge between the two shells. The ciliated part which comes out of the shell is the velum - hence veliger. The velum is used for swimming and also for feeding.

Look after it for a year or two and you could have an oyster (or mussel or....) for dinner!

regards

Brian
