Actinopteri (ray-finned fishes) > Lophiiformes
(Anglerfishes) > Ceratiidae
Etymology: Ceratias: Greek, keras = horn or horned, refers to the lure projecting from the snout (Ref. 86949). More on author: Norman.

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 88.0 cm TL (female)
soft rays: 4. Distinguishing characteristics of metamorphosed female: pair of distal esca appendages; illicium length 19.1 to 28.2% SL; presence of 2-6 vomerine teeth in large specimens; darkly pigmented proximal one-half to two-thirds of escal bulb, oval shaped distal portion, proximal portion tapering into stem of illicium; 2 slender escal appendages arising anterior to escal pore, each appendage nearly always bifurcate, trifurcate or multibranched; escal pore at apex of bulb, raised on pigmented papilla in specimens 75 mm and larger (Ref. 86949).
Majority of collected materials taken by trawls that reaches maximum depth of greater than 650m (Ref. 86949).
