In 2012, researchers at the California Academy of Sciences added 137 new relatives to our family tree, enriching our understanding of the complex web of life on Earth and strengthening our ability to make informed conservation decisions. The new species include 83 arthropods, 41 fishes, seven plants, four sea slugs, one reptile, and one amphibian. They were described by more than a dozen Academy scientists along with several dozen international collaborators.
