The Single Celled Animals

I've been reading about protozoa, the single-celled animals that occupy nearly every habitat on earth. The book, The Parade of Animals, was my mother's from high school and all the photographs are in black and white but the descriptions of the coloration and form of these single cells of life give you a sense that nothing was too small for the aesthetic sense of an artist that must indeed have a fine palette of pigments and an amazing comprehension that nothing can be too small for such delicate sculpture that Michelangelo would have to gaze at as the miraculous in miniature.
