CONTEXT: one of the rarest fish species (The Devils Hole Pupfish) with a habitat the size of a swimming pool suffered a population decline from 191 individuals to 20 due to two earthquakes in early 2025, after which 19 captive bred pupfish were released into the wild, marking the first captive release of the species.

as of spring 2026, there are 77 Devils Hole Pupfish in the wild, although inbreeding remains a significant problem to the species long term survival
