Actinopterygii (ray-finned fishes) > Lophiiformes
(Anglerfishes) > Ceratiidae
Etymology: Cryptopsaras: Greek, kryptos =secret, hidden + Greek, psaras = fisherman (referring to this genus' tiny illicial bone, almost entirely covered by tissue of the esca) (Ref. 86949); couesii: Named for the eminent ornithologist Elliot Coues (Ref. 4525). More on author: Gill.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 0 - 3085 m (Ref. 58018), usually 500 - 1250 m (Ref. 36494). Deep-water; 81°N - 52°S, 180°W - 180°E
Tropical and subtropical parts of all oceans. South China Sea (Ref.74511).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.3 cm TL male/unsexed; (Ref. 4494); 44.0 cm TL (female)
Males dwarfed, becoming parasitic on females. Maximum size of free-living males is 1.05 cm (Ref. 4494). Females are oviparous, with planktonic larvae (Ref. 36494). Eggs are presumably contained in floating gelatinous rafts (Ref. 36494 ).
Females are oviparous, males are parasitic (Ref. 36494).
