Etymology: Callechelys: Greek, kalos, kallos = beautiful + Greek, enchelys, -yos = eel (Ref. 45335). More on author: Snyder.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 4 - 24 m (Ref. 58302), usually - m (Ref. ). Tropical; 0°C -
Pacific Ocean: known only from the Hawaiian Islands, Midway Island and French Frigate Shoals.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 104 cm TL male/unsexed; (Ref. 27478)
Benthic (Ref. 58302). Adults of most Callechelys spend most of their lives within the sediment and do not form permanent burrows. This species is exceptional and has on rare occasions been dip-netted beneath lights at the sea surface at night and has been seen encountered with its head protruding from the sand by divers at various Hawaiian locations (Ref. 27478).
