Spelaeorchestia koloana, the Kaua?i cave amphipod or ?uku noho ana in Hawaiian, is a cave-dwelling crustacean only found on the Hawaiian island of Kaua?i. It is eyeless and measures 7-10 millimetres (0.28-0.39 in) long. It is only known from ten populations, and eats decaying plant matter and other decomposing material.
The Kaua?i cave amphipod is endemic to the caves on Kaua?i, Hawaii. Its main predator is the Kaua?i cave wolf spider Adelocosa anops, another endemic of the Kaua?i cave. It is listed as an endangered species under the Endangered Species Act, and on the IUCN Red List.
