Galápagos Damselfish :: Azurina eupalama
Bad at Goodbyes :: Episode 075

On today’s show we learn about the Galápagos Damselfish, a critically endangered, possibly extinct marine fish native to the ocean waters of the Galápagos Islands, an archipelago in the Pacific Ocean, a province of Ecuador, roughly 600 miles west of the South American Ecuadorian coast. Its scientific name is Azurina eupalama and it was first described in 1903.
