Found in rocky intertidal. 2mm diameter. Attached on the girdle of Placiphorella velata.
Spotted this in some dirt on Piedmont Ave. Don't remember the exact location, but I'll try find it again in a few days to see if it's changed.
Protozoa are a diverse group of unicellular eukaryotic organisms, many of which are motile. Originally, protozoa had been defined as unicellular protists with animal-like behavior, e.g., movement. Protozoa were regarded as the partner group of protists to protophyta, which have plant-like behaviour, e.g. photosynthesis.
