Etymology: Randallichthys: After John Randall, marine biologist, Bishop Museum of Hawaii; he worked in systematic ichthyology with fishes of Indopacific region + Greek, ichthys = fish.
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marino benthopelagico; distribuzione batimetrica 150 - 300 m (Ref. 55). Deep-water; 35°N - 24°S, 121°E - 147°W (Ref. 55)
Pacific Ocean: known only from the Hawaiian Islands, Cook Islands, New Caledonia, and Okinawa, Japan but probably widespread in the area. Recently recorded from Tonga (Ref. 53797). Eastern Indian Ocean: Scott Reefs, northwestern Australia (Ref. 82665).

Estimates based on models
Preferred temperature (Ref.
123201): 13.3 - 23.4, mean 19.3 °C (based on 11 cells).
Phylogenetic diversity index (Ref.
