Description

The Owens pupfish is a small pupfish endemic to the Owens Valley in California. The species reaches only about 4 cm; males turn bright blue in breeding dress, while females are olive-grey with cross-bars. It lives in desert springs, pools and marshes and tolerates warm, saline water. It is famous for its 1969 rescue, when the entire species was temporarily carried in buckets. Owing to its minute range it is severely threatened. The IUCN assesses it as Critically Endangered (CR).
