[1] The native habitat of the Kamchatka flounder ranges from the Shelikof Strait and the Aleutian Islands in Alaska, across the Bering Sea, to the Gulf of Anadyr, Kamchatka Peninsula and the seas of Okhotsk and Japan.

[2] The Kamchatka flounder's diet consists of fish and zoobenthos organisms such as squid, cuttlefish, shrimps, prawns, amphipods, mysids, mollusks and marine worms,[1] though the most important prey item is the walleye pollock, which accounted for 56-86% of stomach contents by weight in one study.

[3] Kamchatka flounder have been found in the stomachs of only 17 different species of fish in the Bering Sea and Aleutian Islands, including Pacific cod, Pacific halibut, pollock, arrowtooth flounder and sculpin.
