Possible extinction[
The El Niño–Southern Oscillation of 1982 and 1983 led to an increase in the water temperature near the Galápagos Islands.Plankton production was reduced for at least one year, leading to drops in the populations of many planktivorous fish, such as the Galápagos damsel. Despite intensive searches during the next decade,it was not seen again. The International Union for Conservation of Nature lists the fish as a critically endangered species, and one which is possibly extinct. It notes, however, that "populations ofA. eupalama may still exist on islands off Peru that have warm temperate conditions, such as the Lobos Islands
