This site is dedicated to the beauty and science of nature and to the joys nature brings to those who explore it. The material here is organized according to the biological principles of Taxonomy. Two major types of these directories exist, the kingdom-based directories and other types of directories. This is a collaboration of the Illinois State Academy of Science, the Illinois State Museum, the Weizmann Institute of Science, and the Henson Robinson Zoo.
Images are an aid to identification, showing different stages, states and views of the organisms.
