This flagellate is about 31 microns along its longest axis. Two flagella can be dimly seen extending to the right. They are very active and much longer than is seen here. There are also two structures extending out to the left. One is another flagellum that seems to always want to trail towards the posterior. The other structure seems to be an anchor. It's attached to the substratum. It actually coils as the protist moves. The flagellate almost became entangled in it at one point.
I am confident that this is a rotifer, but is it an egg (new organism) or a cyst (a survived organism?) The material inside is very active. The eyespot can be seen as a very dark red spot half way down the organism, a bit left of midline. The entire structure is 165 microns along its longest axis.

Is this a worm or a fly larva? I suspect the latter. This organism is about 5 mm long.
