Climate / Range
Subtropical; 12°C - ? (Ref. 1964)
Eastern Atlantic and the Mediterranean: Iberian Peninsula from Bay of Biscay to Cape Verde.
Bathybenthic (Ref. 1962). Large individuals were found down to 1400 m and small ones were found down to 1835 m (Ref. 1962). Exhibits up-slope ontogenetic migration of juveniles to depths shallower than 1200 to 1400 m (Ref. 1958). Members of the class Cephalopoda are gonochoric. Male and female adults usually die shortly after spawning and brooding, respectively. Mating behavior: Males perform various displays to attract potential females for copulation. During copulation, male grasp the female and inserts the hectocotylus into the female's mantle cavity where fertilization usually occurs.
