Ecology of Nezumia bairdii
 
Main Ref. Langton, R.W. and R.E. Bowman, 1980
Remarks Most common in 90-700 m but found in shallower areas with cold surface waters; with size-related depth distribution; catches increase with depth and peak catches during the day (Ref. 86779). Taken much shallower in areas with cold surface waters. Feeds primarily on euphausiids, amphipods, and polychaetes, although a 200 mm individual had many copepods in its stomach (Ref. 1371). Consumed primarily benthic organisms (Ref. 51343). It is preyed upon by swordfish (Xiphias gladius). Parasites of the species include 3 myxosporidians, 2 cestodes, 3 nematodes, 3 trematodes, 1 monogenean (Diclidophora nezumiae and 1 acanthocephalan (Ref. 5951).
