An illustration for a taxonomy game about identifying species; the image shows different species of fish and of plankton in the ocean

Our world is full of different plants, animals, bacteria, and other life. But how do we know which species is which? How can we identify something that we find? Scientists have built tools called taxonomic keys that help us do this. These let us learn to identify the differences between organisms. Take a trip to the ocean to help researchers identify different species of fish and zooplankton in Keys to the Ocean.

To learn more about taxonomy and species identification, visit our story page about Taxonomy.
