Adults benthopelagic from 800 to 1,350 m, juveniles mesopelagic from 300 to 500 m (Ref. 6181). Up until recently, fisheries catch landings of A. carbo, a sympatric species in the waters of Canary and Madeira islands, were mixed with A. intemedius.

Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Displays determinate fecundity (Ref. 108695). Mature individuals undertake horizontal migration to spawning and nursery grounds (Ref. 108708).
