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
Marine; benthopelagic; depth range 150 - 300 m (Ref. 55), usually - m (Ref. ). Deep-water; 0°C - ; 31°N - 28°S, 124°E - 149°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).

Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm SL male/unsexed; (Ref. 9821); common length : 40.0 cm SL male/unsexed; (Ref. 9821)
soft rays: 9. Head blunt. Interorbital space flat. Eye large. Preorbital bone relatively narrow. Snout short. Lower jaw protruding. Pectoral fins short, not reaching level of anus. Lower lobe of caudal fin with some rays excessively produced and filamentous in young. Scale rows on back parallel to lateral line.

Estimates based on models
Preferred temperature (Ref. 115969
): 13.3 - 23.4, mean 19.3 °C (based on 11 cells).
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00687 - 0.03334), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (48 of 100) .
