context_page_description: The deacon rockfish is a rockfish of the genus Sebastes.
context_section_description: Between 2002 and 2004, phylogeographic research on blue rockfish (Sebastes mystinus) identified a distinct genetic subpopulation, which was sampled between Cape Mendocino in northern California and Neah Bay, Washington. Subsequent research identified further genetic evidence supporting this distinct subpopulation, as well as demographic differences and evidence for reproductive isolation. The subpopulation was cited as an example of incipient speciation. In 2015, distinct morphological traits were identified for the northern subpopulation and it was recognized as a distinct species, classified as Sebastes diaconus.
