For Chinook salmon, the urge to return home and spawn isn't just strong — it's imperative. And for the first time in more than 65 years, at least 23 fish that migrated as juveniles from California's San Joaquin River and into the Pacific Ocean have heeded that call and returned as adults during the annual spring run.

These related species — which, along with chimaeras, are known collectively as chondrichthyans — include some of the most threatened marine fishes in the world. Sharks and rays face a variety of threats depending on where they live and swim, but the biggest risk comes from overfishing, which takes a noticeable toll on these slow-growing, slow-to-reproduce animals. As a result, nearly 1 in 4 species of chondricthyan fishes is estimated to be, or assessed as, threatened, according to the IUCN Red List.
