Radiolaria (or sometimes called "Radiolarians") are single-celled creatures (Protozoa) usually measuring 0.1 - 0.2mm. They have existed since the pre-Cambrian age, and still exist today, though many have now gone extinct.

Quoted from Wikipedia "Protozoa"
"....Historically, the protozoa were regarded as "one-celled animals", because they often possess animal-like behaviors, such as motility and predation, and lack a cell wall, as found in plants and many algae. Although the traditional practice of grouping of protozoa with animals is no longer considered valid, the term continues to be used in a loose way to identify single-celled organisms that can move independently and feed by heterotrophy....."

In the nineteenth century, Ernst Haeckel, German biologist, naturalist, philosopher, physician, professor, marine biologist, and artist sketched the intricate and incredible skeletal forms of Radiolaria.
