The appellation cannibal fish stems from discoveries of partially digested conspecifics in captured specimens. The longnose lancetfish can also be found as far north as Russia. This expansive geographic reach has caused for the species to be accidentally caught by some tuna fisheries. Daily vertical migrations from the epipelagic all the way down to the mesopelagic or bathypelagic zones are undertaken to find food.

The known predators for A. ferox include yellowfin tuna, opah, fur seals, Pacific cod, and salmon shark. Predators are known to change depending on the ocean region. When A. ferox was removed from these regions of the Pacific Ocean, there was a negative effect on the ecosystems that showed the importance of this species as both a predatory and prey type. The gut of the A. ferox is a large, blind sac that also has a very unique biological response to food. Unlike other hermaphroditic fishes, A. ferox has two distinct testicular lobes that are independent from the ovarian region. This species also has an absence of a pair of diverticulae in the female reproductive section, which in other hermaphrodites is used for spermatophore uptake. Macroplastic fragments and rope fragments were the most commonly found plastic in the stomach contents with white and clear colored plastics seeming to be favored. A. ferox also accounts for 2% of all bycatch by circle and j hook longline fisheries in the Bay of Bengal. Survival of being bycatch in these types of nets is low only one third of A. ferox survive.
