Sphaeroeca, a colony of choanoflagellates (aprox. 230 individuals)

The choanoflagellates are a class or phylum of collared cells. Some species are single cells, some are multicellular. They are eukaryote flagellate cells of microscopic size. They do not have chloroplasts, and are heterotrophic. Some consider they form the simplest phylum of animals; others consider them to be protists.[1][2]
