This sea creature lives in the surface layers of water with depths of no more than 200 metres and in waters with a temperature between 0.4 and 28°С. During its migration period, the squid approaches the shores of the islands in Peter the Great Bay and frequently appears within the borders of the Far East Marine Biosphere Reserve. In the warmer years, the northern border of the calamari habitat expands up to the Commander Islands; its mass accumulations were registered up to the 57°n.l.
The Far East Marine Reserve works to study and preserve the marine mollusk fauna. The squid is the major connecting link between the coastal and open sea communities in the marine environmental systems under the Reserve’s protection.
