John Otterbein Snyder (1867-1943) was an American zoologist.
As a student he met David Starr Jordan who inspired him to enter zoology. He eventually became a zoology instructor at Stanford University and served there from 1899 until 1943. He went on several major collecting expeditions aboard the USS Albatross in the early 1900's and organized the U.S. National Museum's fish collection in 1925. The same year he also declined the director-ship there so he could return to Stanford. He was a long-term member of the California Academy of Sciences and worked for the California Bureau of Fisheries. He wrote many articles and papers as well as describing several new species of sharks.
In 1905, Snyder, then Assistant Professor of Zoology at Stanford, published Notes on the fishes of the streams flowing into San Francisco Bay in Report of the Commissioner of Fisheries to the Secretary of Commerce and Labor for the fiscal year ending June 30, 1904. This work is significant in its historical documentation of the native fishes of San Francisco Bay watersheds.[1]
