Ecology of Anotopterus nikparini
 
Main Ref. Ambrose, D.A., 1996
Remarks Found in a wide range of depths, sometimes near surface (Ref. 2850) to below 2,000 m. Larger adults inhabit colder water toward the poles, whereas, the young and smaller adults inhabit more temperate regions (Ref. 35956). Feed on mollusks, crustaceans, marine worms, coelenterates, salps, and fishes (Ref. 4525, 6885). Its distensible body wall and large stomach can accommodate prey up to half of its own length. Preyed upon by albacore, Pacific lancetfish, halibut, steelhead salmon, blue shark, pomfret, and whales (Ref. 6885).
