The biology of the Cuvier’s beaked whale, Ziphius cavirostris Cuvier, 1823, in Russian waters remains almost unstudied. The species is encountered rarely elsewhere in the seas of Russia, except for the waters off the Commander Islands. Currently, some researchers express doubt about the accuracy of the known Cuvier’s beaked whale records in the region. This report provides information on the confirmed encounters with Cuvier’s beaked whale off the Commander Islands and eastern Kamchatka.
