Actinopteri (ray-finned fishes) > Lophiiformes
(Anglerfishes) > Chaunacidae
Etymology: Chaunax: Greek, chaunax, -akos = a conceited man (Ref. 45335); stigmaeus: Specific name mean 'spotted' (Ref. 33606). More on author: Fowler.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 90 - 730 m (Ref. 7251). Deep-water; 40°N - 36°N
Western Atlantic: Georges Bank to Norfolk Canyon.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.5 cm TL male/unsexed; (Ref. 58471); common length : 20.0 cm TL male/unsexed; (Ref. 7251)
One of the specimens (NCSM 41116) represents a new size record for the species (25.5 cm SL, 30.5 cm TL), and another (GMBL 02788) represents a southerly range extension (31°23.94'N). All specimens observed exhibited similar behaviors of sitting on the bottom on top of dense beds of dead coral (Lophelia pertusa) (Ref. 58471).
