HMS Challenger and the California Academy of Sciences

Walter K. Fisher was Curator of Invertebrates at the California Academy of Sciences (1917-1953), Director of the Hopkins Marine Station, and Stanford Assistant Professor of Zoology. Fisher died in 1953 and his collections have been housed at the Academy ever since.

Fisher wrote many publications. Among the most important are monographic treatments of starfish from the Philippines Sea, the North Pacific, and the Hawaiian Islands, alongside numerous other publications.  

This specimen was identified by Walter Percy Sladen who wrote the report on the starfish.
