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 / Climate / 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
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.3 cm TL male/unsexed; (Ref. 4494); 44.0 cm TL (female)
Tropical and subtropical parts of all oceans. South China Sea (Ref.74511).
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 ).
